[Recommendation] CGW pushes 86 with double out of the tail section exhaust

[Recommendation] CGW pushes 86 with double out of the tail section exhaust

No car factory will be "must change" positioning, but there are many car manufacturers will build cars according to such standards, 86/BRZ close to us is such a presence.This is a car that has been positioned in the eyes of fans all over the world. It will lose his meaning without changing it. In all the conversion projects, the exhaust seems to be a "must change", and each owner of the 86 has 10,000 reasons to tell you why you should change the exhaust. In the shallow cognition, 86 is also a small sports car, and the sports car should have a roaring exhaust sound and a domineering exhaust appearance; in the deep understanding, 86 is a performance car, high-transfer property FA20 A better exhaust system is needed to further release its power. A good set of exhaust can certainly meet the above two basic needs.The following is a dual exhaust from CGW for 86/BRZ, demonstrated by a thrilling Rocket Bunny V3 wide body BRZ. Obviously, this car's choice of exhaust is oriented to sound and appearance. The 86* orthodox exhaust form must be a single-barreled bevel, the so-called JDM Style, but the double-out is not violated, let alone The V3 rocket rabbit is very imposing. CGW's mid-end segment is just right with RB enveloping. The appropriate tail radius and form, the appropriate sound wave performance, in fact, there is a suitable intrinsic performance, even if the car has more turbines or other forms of power in the future. Upgrade, this set of exhaust can also be suitable. It has been reported earlier that CGW's newly introduced 3D scanning technology and horsepower machine cooperation development have gradually been applied to actual production, so the advantages of CGW products in comparison with other brands will be very accurate installation and performance.

Giulia uses the CGW mid-end variable exhaust

Giulia uses the CGW mid-end variable exhaust

After all, Giulia is a niche car, and even from the picture into our life is so silent, in addition to Alfa Romeo is not as good as the opponent knows how to market, I would rather believe that this is Alfa Romeo's way of doing things.I believe that no one will doubt Giulia's movement positioning. From brand pedigree to product design, Giulia's sports characteristics are pure. Don't say it's pure. If a car has a trace of sporty elements, it will be hooked up with the modification, so you can imagine that the street Giulia is really getting bigger in the future. It is estimated that there will be no more cars.    The sale of the car does not affect the development of the keen refurbishers. In this respect, domestic refiners are not behind, especially the exhaust manufacturers who are at the forefront. CGW** is a representative. The first batch of old qualified self-owned brands in China has been doing a good job in pushing new products. And not only can the first time to meet the owner's desire to convert, the quality and performance of the independent brand is not the same. CGW has always played a leading role in the face of independent brand image, new technology and new technology, new equipment and new ideas, have to say that CGW is still very careful in innovation. * Recently introduced a new horsepower machine, which is a pioneering work among independent brand exhausters. It is worthy of praise for this kind of investment. It is impossible for independent brand exhaust to stay at the level of changing sound. The essence of exhaust gas conversion - performance improvement is the way out. It is commendable that CGW can see this early, and it is believed that the addition of horsepower will increase its manufacturing technology and products in the future.Say back to this set of exhaust. This is a set of variable valve exhaust in the middle section, the appearance adopts the CGW uniform style sandblasting treatment, the middle section is equipped with a small middle drum, and the center of the parking space is also a small tail drum. * Importantly, the two sides of the tail section are designed with variable valves, and the sound and exhaust paths are controlled by the owner. Overall, this is a set of competitive exhaust, especially when the valve opens into a "small pass", which is in line with Giulia's needs, whether it is a thick sound to set off its sporty shape, or efficient exhaust efficiency to assist its The 2.0T engine produces output, and this CGW exhaust can play a good role.

IS250 uses CGW variable valve in the tail section

IS evolved to the third generation of XE30. Here, Lexus has put his sporting characteristics at the balance of the **, at least the appearance of the XE30 will not let you question his positioning, but if it is too Then it will slide to the situation of Altezza that year, the players said that the ordinary people do not understand the embarrassment. In terms of describing the characteristics of sports, Lexus has a strong foundation, especially the design language system of the generation where XE30 is located. The whole product line is surrounded by this strong sports wind. In the era of young consumerism, this is obviously The way to go with the favor.The body of the XE30 IS is basically unable to pick out a lot of design elements that violate the sport, not to mention the F Sport model. It can be said that Lexus F can really pick out the point of dissatisfaction - exhaust. We know that the four-exhaust exhaust of the "eight-character" on both sides of the F-vehicle is the symbol of F. I believe that the IS F of this generation will still have this feature, just like the little brother "pre-announce" below. . I also believe that every bloody Lexus owner is eager for the "F layout". It is not difficult. The customization ability of the independent brand is so developed. Do a F Style exhaust minute to see how CGW can help you achieve F shape. .Figure: A small suggestion, the nismo at the end of the car is removed, unless the owner is working in the NISMO department of Dongfeng Nissan, but with a heart of Lexus, it is another matter.This is a variable-valve tail valve exhaust for IS250 (XE30). It is made of stainless steel and has a sandblasted surface. It has high texture and good anti-rust ability. There are two drums in the middle section of the X-shaped cross, and two slightly larger tail drums in the tail section. Don't worry that the sound will be over-suppressed. Don't forget that *the front is a V-shaped six-cylinder machine. This layout is just right. The ability to play the V6 sound is not too noisy, and don't forget the existence of the valve, whether you want to be radical or conservative, a remote control can do it. **F-shaped four-outlet nozzles stacked on top of each other are also the highlights. Look at this size and feel that the original rear bumper can also be accommodated. If you want to replace the rear bumper, you must inform CGW. Of course, the meaning of a set of exhaust is not all in appearance and sound, performance improvement is also necessary. The IS250's 4GR-FSE 2500cc output is not too much, but the advantage of V6 is the linearity and naturalness of the output. This linear output of NA will be further advanced. CGW optimizes the exhaust path by increasing the diameter of the pipe to achieve an improved exhaust efficiency, making the output of the IS250 smoother.

Second third3 Series Powerful Competitor Modified Circle Luxury Sports Model ATS2016-08-23 11:06:43 Source: GTUU changed to the Internet  In the domestic luxury mid-size car market, BBA has always occupied a dominant position. The A4, 3 series and C-level each have their own strengths, each forming a distinct product positioning. Among them, the BMW 3 Series is a natural sportsman. With the launch of the Cadillac ATS in 2013, the 3 Series has been strongly impacted by new rivals. It is also a front-mounted rear drive, also a 2.0 high-power turbocharger, ATS has Gradually captured the hearts of the pursuit of sports drivers.Cadillac ATSThe Cadillac ATS is a young and energetic model in the history of the Cadillac family. Its design concept is agile and light, and everything is worth the driver's favor. Its appearance has clearly defined its own goals, and it has also set off a series of contrasting frenzy. Who is the luxury sports coupe?       I don’t know how to control the power. In fact, ATS lost space, but now the emergence of domestic ATS-L has made up for this deficiency. In the new car sales market, the BMW 3 Series and the ATS-L two old rivals have started a new contest; in the car modification industry, many excellent modification cases of ATS are also launching a new round of challenges to the big brother.ATS upper body VOSSEN VFS-1 wheelMultiple spoke designs highlight sporty temperamentSince the ATS is an athletic coupe, the handling requirements are naturally not casual, and it is necessary to equip it with an excellent wheel. Rather than lifting the performance parameters, it is not as good as reducing the load on the wheel of the vehicle. The lightweight wheel can reduce the unsprung mass and provide a better control experience for the vehicle. At the same time, the artistic wheel enhances the temperament of the vehicle.Large size wheel** visual impactGun gray painting matches body **VOSSEN's VFS series is such a wheel product with both aesthetic and solid quality. The VFS-1 series wheels are made by spin casting. Spinning is actually a quite unique wheel manufacturing technology. The rims produced are of high strength and light weight, and have the same attributes as forged wheels.Aibach short spring and anti-roll bar upper body ATSThe modified circle is often popular with "a low cover and ugly, and a hundred changes to the first". For ATS, having a posture close to the ground and a lower driving posture is undoubtedly a hard indicator for the king of the same level. There are many ways to reduce the posture of the body. It is common to modify the suspension system. It is simple and easy to change a short spring.Aibach ATS special short springAibach anti-roll bar, iconic red paintChassis height drops by two finger widthEbbach from Germany is the world's leading spring manufacturer, this time bringing a short spring product developed specifically for ATS. With its cutting-edge technology from the racing car, it can effectively reduce the chassis height of ATS and achieve better handling performance. . In addition to the high-performance short spring and the original shock absorber**, the anti-roll bar is one of the main components of the suspension system, which is the finishing touch for the handling performance of the Cadillac ATS. With an adjustable shaft, the driver can adjust the stabilizer bar effect according to driving preferences.CGW Cadillac ATS mid-end valve exhaustCadillac ATS is very tough with its family-style design. The headlights are sharp and the body is sharp and angular. It can be said that the value of this is completely in line with the requirements of the coupe. In terms of sound waves, the original exhaust is obviously softer. It is necessary to choose a set of exhaust systems.CGW straight through sectionCGW with three-way catalytic headTwo-way total exhaust design with valve unitAs the leader of the domestic exhaust gas refit brand, CGW has been relying on its strong research and development capabilities for many years, and its products have covered most of the models on the market. This time, CGW has launched a full-stage exhaust system for the ATS model. The new CGW Cadillac ATS special exhaust is made of SUS304 stainless steel. The whole body is made of matte coating technology, supplemented by a bright polished tail nozzle, which has a very good performance in corrosion resistance. The highlight of the exhaust ** is the design of the variable valve. It is equipped with CGW special valve control equipment. The valve is easy to open and close, and the sound is fascinating.Bright polished tailThe sense of technology has always been pursued by CGW, and mobile phones have become a necessity for popular life. CGW cleverly integrates the functions of mobile phones into the exhaust system. The new CGW's “Black Technology” mobile APP control system can control the opening and closing of the valve at any time, with a simple interface design, and the exhaust sound can be adjusted by touching the finger. The mobile APP and the on-board controller are two-pronged to enhance driving pleasure.CGW Bluetooth Control SystemDare to challenge the BMW 3 Series, which is focused on control, such a strong opponent, Cadillac ATS is not a mouth-watering, it does have excellent performance and strong conversion potential without losing 3 series, plus more and more ATS modified products on the market. I believe that it will not be long before ATS will become the leader in the car modification industry.

For a long time, the German luxury brand BMW 3 Series, Mercedes-Benz C-Class and Audi A4 have been the main players in the sports mid-size car market, and other products are difficult to compete with. With the launch of the Jaguar XE, with its young positioning, cool exterior design, and unspeakable sports talent, it has quickly attracted the attention of many consumers.     This fledgling "sportsman" will directly target the BMW 3 Series as soon as it goes public. Everyone knows that the first few pioneers, especially the 3 series of modification cases, are endless, so the Jaguar XE, the little leopard, can finally get the acceptance of this part of the rider, and its own conversion potential is crucial.But to say that the modification is not alone, it can be explained by white. This has to be achieved by some brands to launch the corresponding modified parts. At present, the modified parts for XE are still relatively small, but it does not mean that there is no. CGW, a domestic first-line brand that has always had a keen insight and product development capability for the market, has recently launched a professional exhaust system for Jaguar XE.When it comes to the CGW brand, the modified fans will not be unfamiliar. Founded in 2009, the brand has been determined to become the leading brand of exhaust in China since its inception. Under the implementation of this concept, CGW has invested a lot in the research and development of exhaust products and the quality control of its products. Consumers bring high-quality exhaust products, and compared to the high price of some imported products, CGW's all this is achieved without the consumer having to invest too much.This Jaguar XE exhaust product uses the most popular controllable valve technology. When the valve is closed, the internal pressure of the exhaust gas will be formed, so that the vehicle can be lifted with low twist. When driving in the urban area, there is no need for the uncomfortableness of the breath due to the low twist loss, and the sound is very close to the original. The effect of the factory will not cause the consequences of disturbing the people. When the valve is opened, the low and thick exhaust sounds are instantaneously high, and the horsepower of the vehicle is completely vented. With the continuous increase of adrenaline, the title of the high-performance sports coupe is deserved.If you are the owner or prospective owner of Jaguar XE, and have a very good idea for car modification, please contact the merchant for advice:Jaguar XE mid-tail bilateral single-out valve exhaustAdd valve 8500No valve 4500Shanghai Hao Li Auto Parts Manufacturing Co., Ltd.Website: www.shcgw.cn

For refitting enthusiasts who are looking for passion and speed, hearing the roar of a car can instantly make your blood flow faster. You can increase the return rate of your car on the road and let all passers-by look at you. But it’s not a big voice, it runs fast. Some of the modified cars’ sounds are transmitted to your ears when they are far away, but they haven’t seen the car flying for a long time. ** Very disappointed to see a car “crawling” from you. Over.Exhaust pipe modification steps / methods1. Modification into the exhaust is not blindly to the inside of the money, there are many modified brands for different vehicle factions. Japanese cars generally use the very popular HKS intake and exhaust. If it is a European and American car, there will be other brands such as ABT to modify the vehicle. Just like playing basketball and playing football, it is impossible for football players to wear basketball shoes to compete. Therefore, the modification of the exhaust is also very particular, not a good brand will be suitable for their own car. It is only necessary to choose a modified piece that suits your car. 2. In fact, the exhaust is generally divided into straight row and back pressure. The straight-line sound is relatively larger and the caliber is larger, and the exhaust is smooth and suitable for high-speed driving. The sound of the back pressure is relatively smaller than the straight row. During the process of exhausting the exhaust pipe, a loop is effectively prevented to prevent the vehicle from being twisted. The sound will burst out when the speed reaches 2000-4000 rpm. 3. In the case of intake air, most naturally aspirated cars are recommended to use high flow style, because the effect is not obvious when using mushrooms or bellows. The high-flow style is chosen because of the fear of excessive gas storage after replacing the exhaust gas. For turbocharged cars, you must use mushrooms. This will ensure that the engine's intake air is sufficient to ensure the normal running of the vehicle. 4. The knowledge of the exhaust pipe is also very large, generally divided into the middle section of the head section (plantain, head coke) and the tail end. Each segment has its own different effects and ability to improve the performance of the vehicle. How to choose them is also very particular. 5. Head section: Generally speaking, we call it head coke or plantain. Changing the head coke generally improves the vehicle's dynamic performance. It is conservatively estimated that the replacement of the head coke may increase the horsepower by 10-20 horsepower. This is also the primary modification. A good way to improve your power. If you change the head focus, it may cause the exhaust sound to be louder. If you can't stand the noisy riders, it is not recommended to replace it! 6. This picture is a double-out mid-tail swallow drum, which is also the original exhaust pipe, which reduces the welding problem and directly installs the interface between the welding and the head coke. If you are very focused on exhausting, you may have to go through some careful calculations to burn your own exhaust pipe, or buy different brands of exhaust pipes for welding, the effect is very good. It is also more popular nowadays. Some riders use straight rows to pursue fascinating sound waves. The middle section will weld a back pressure hub to improve the power during low-twisting, which will enhance the vehicle's low-twisting power. 7. The choice of the end is * primary modification, when you fall in love with the modification must have lost its fascinating sound. It can completely indulge you in the roar of a car, just like listening to a wonderful performance. The size of the tail is not large, but it is the main source of sound. Just like the above mentioned riders can choose straight or back pressure drums, for the enthusiasts and modified riders can not only use 1 with the exhaust pipe, a "note" is impossible to meet them.点击图标下载 App

    The tail section of the exhaust pipe is part of the exhaust system, and it is also the third stage of the exhaust system. The structure is basically the same as that of the middle section. The original specification of the exhaust pipe material is also galvanized iron. It is made of plate and iron pipe, and the inside is also composed of back pressure partition and silencer cotton.Automobile exhaust pipe modified car exhaust pipe modificationThe high-performance tail section exhaust pipe casing is also made of durable and heat-resistant stainless steel material. The inner part is smoothly discharged by the rotary back pressure baffle. The stainless steel sound-absorbing cotton is wrapped with fiberglass silencer cotton, which can be reduced. At the same time of exhaust resistance, the engine maintains a reasonable low-speed torque output, and greatly prolongs the service life of the muffler cotton, so that the exhaust pipe maintains a stable exhaust smoothness while maintaining a normal muffling ability for a long time.Automobile exhaust pipe modified car exhaust pipe modificationIn recent years, the titanium alloy tail section exhaust pipe has not only high temperature resistance and durability, but also the exhaust efficiency is greatly improved due to the increase of the exhaust gas temperature, and the titanium alloy tail section exhaust pipe is light in weight and high in material strength. Compared with the stainless steel tail section exhaust pipe of the same specification, the weight can be reduced by 40% and the pipe wall can be 30% thinner. However, due to the difficulty in processing titanium alloy materials and the need for laser welding, the cost is nearly double that of stainless steel products.

However, due to the difficulty in processing titanium alloy materials and the need for laser welding, the cost is nearly double that of stainless steel products.

    Do you know the misunderstanding of these exhaust gas modifications?

    For those who know the car or do not understand the car, an atmospheric exhaust pipe or a sophisticated exhaust system is considered a very good modification. It can make a car instantly show its super appeal. In addition, when the conversion industry involves the modification of the power part, then the modification of the exhaust is usually considered to be inevitable.Replacing a vehicle with a higher performance intake and exhaust system allows the engine to draw multiple rows of air to enhance power. Compared with foreign modification, domestic modified car enthusiasts prefer to modify and improve the exhaust system. I think the reason for this is that the modified exhaust pipe and the sound of the sound are quite a preference of the domestic people. Now walking on the street, from time to time, you will hear the sound of exhausting the air, giving the listener a feeling of height. Unconsciously, I will think of modification. It can be seen that the modified exhaust system is very common in the modified car industry, so today we will talk about the misunderstandings of people in the modified exhaust system.  Misunderstanding 1: The original car exhaust performance is relatively poorMany people think that between the modification of the exhaust system, the original exhaust performance is much worse than the modified. In fact, because the original exhaust system used by the original manufacturer has been tested by professional equipment, the vehicle's power performance and environmental performance and fuel have been greatly coordinated. It is a product designed after many data integrations. For example, a small displacement car with weak power, the original exhaust gas is generally not too smooth, because this design can solve the low torque of the small displacement engine itself, and the exhaust resonance effect can be generated by proper return. It is more suitable for use on city roads. And after the exhaust system that we have modified, we hope that the exhaust gas will achieve a lot of problems, such as the stability of power performance and the problem of increased fuel.   Myth 2: The louder the sound, the bigger the horsepowerFor the exhaust system, the part responsible for eliminating the noise is in the exhaust tail section or the middle section. It is only a simple modification of the exhaust duct to achieve a good sound wave effect, and does not improve the power performance. The reason is very simple. The exhaust gas from the engine passes through the exhaust manifold, the three-way catalytic converter, and then reaches the middle section of the exhaust pipe to reduce resonance** to the tail silencer. Therefore, before the exhaust tail section, each component will form a resistance to the exhaust gas, so it is not a large horsepower to say that the sound is large. Just changing the exhaust pipe at the end will not affect the power performance, even if it is small, it can be ignored. As long as the entire exhaust pipe is replaced by a high-performance exhaust pipe, it will have a very large impact on the power performance, especially after the intake system has been replaced with high performance.In addition, remind the majority of modified car enthusiasts, do not easily believe that the skills of the S drums produced by the unknown small workshops improve the efficiency without losing the low twist. Some cars modified with S drums are even worse than the original ones.   Misunderstanding 3: The thicker the exhaust pipe, the better the exhaust gas pressure is as low as possible.Friends who don't know much about the exhaust system know that the reason for the exhaust performance in the vehicle exhaust system is back pressure, and the level of back pressure can change the dynamic performance of the engine. So is the lower the back pressure, the better the power performance? The answer is definitely no. If the back pressure is too low, the low-velocity exhaust will be too smooth, and the airflow speed will be slow, which will affect the low-speed exhaust efficiency, and the low-speed torque output will decrease, and the power will be reduced.Recognizing the above three misunderstandings, the conclusion is that you must make necessary modifications according to your driving habits. You must not pursue unilateral factors for modification.点击图标下载 App

  • Car maintenance and repair Why should the car be modified?

    Car maintenance and repair Why should the car be modified?

    1. Why should I modify the exhaust?A: Because the original car's exhaust is a spacer type, which limits the car's sound and horsepower. The modified exhaust is straight through, the sound changes, and the horsepower is improved according to the pipe type. At the same time, the exhaust of the original car is iron, easy to rust, broken, and the modified exhaust is made of stainless steel.2. What are the drum types for the modified exhaust, what is the sound?A: The modified exhaust is divided into S drum, street drum, HKS type, M drum.S drum: Mainly improve the starting horsepower, the sound is low, bigger than the original car. Street drum: comprehensively improve the horsepower of the car, the sound of the street drum can be made into a sports car sound or back pressure,HKS type: directly improve the middle and high turning horsepower, the sound is like a racing car, just like the legendary sound heard before the car. Workmanship and imports are comparable.M drum: variable back pressure drum, known as the Austrian fox head, the tail drum body paint, very high-end. The sound is very quiet, only a little louder than the original car, and the sound is low. The overall improvement of horsepower is to modify the high-end goods in the exhaust.3. Why do people say that the S drum runs at high speed and has resonance.A: In fact, the S drum is the tail of the back pressure drum, the sound is low, the starting horsepower is good, the exhaust is smoother when running at high speed, and there is no resonance phenomenon in the real vehicle test.4. Why do all the models change the same tail exhaust, and the effect is different?A: The same model is modified to select the S drum. If one of them is changed to the whole section and the other is only changed to the tail section, the effect is definitely good for the entire section of the exhaust, because there is no ternary limit in the whole section, and the whole section is modified. The gas volume is larger and smoother, so the effect is even better.5. What is the original exhaust?A: The exhaust produced by our factory is produced according to the original model. The position and the bent pipe are the same as the original car. Some models are produced according to the chassis position and can be installed.6, my car exhaust is a middle-tailed body, how to change?A: The modified exhaust can be divided into the middle section and the tail section, which can be changed separately. To change the tail section, the tail section of the original car should be cut off, and the modified exhaust should be put on, and the sleeve should be tightened by the form of the upper buckle. If the middle tail is better, the installation is more convenient.7. Why is the exhaust tail section of my car more expensive than other cars?A: For the end of individual models, it is longer than other models, and some additional costs are required. Such as Cherokee, Zotye models.8. If my car is surrounded, how can I look at the exhaust pipe tail section?A: The exhaust produced by our factory, the tail part of most models is active, and the buckle is tightened, so that the customer can control the length by himself and achieve the appearance of **.9.

    Automobile exhaust pipe modification knowledge Daquan

    Nowadays, the modified parts of the *** are not exhaustive. It seems that after installing a large-caliber and surprisingly sound exhaust pipe, the vehicle will run faster. In fact, this is a misunderstanding. The replacement of the exhaust pipe is negligible for the improvement of horsepower. Especially for some small-displacement natural intake vehicles, it is quite difficult to obviously feel the improvement of horsepower. Conversely, a large-caliber exhaust tail drum has a considerable impact on low-speed torque loss, but a smoother exhaust at high speed is understandable for power improvement.    The key to exhaust performance is speed back pressure    Although the four-stroke engine was originally designed to be completely combustible, the exhaust pipe is pure because of the large number of cylinders in the car, the lack of a separate exhaust pipe for each cylinder, and the consideration of noise, space, overall configuration, and mass production cost. Silencing and cooling the exhaust gas, so there will be problems that are not smooth enough to reduce the engine's performance. Therefore, it is better to describe the modification of the exhaust pipe to increase horsepower. It is better to find the horsepower and play the original output.    The patency of the exhaust pipe is also known as the "back pressure", or it can be called back pressure, back pressure, in short, it is the resistance inside the exhaust pipe, and the design of the banana head, the middle diameter The thickness, the total length of the catalyst, the angle of the beam, and the size of the muffler are all related, and are directly reflected in the exhaust efficiency. The main purpose of the modified exhaust pipe is to reduce the back pressure to make the intake and exhaust flow more smooth, and this is also a disguised extension of the valve overlap time to enhance the vital capacity, thus changing the engine characteristics, thereby improving the response and power of the high speed range. . However, the back pressure is not to say that the lower the better, because if the exhaust is excessively unobstructed, the mixed gas will not be completely burned at the middle and low turn, and the torque will be sacrificed, even when the oil is changed. Low, there is also the possibility that the exhaust gas will flow back to the combustion chamber, so a certain back pressure is needed.    The diameter of the pipe diameter is 10-15%    In general, most of the modification of the exhaust pipe starts from the middle and the tail. The common method is to increase the diameter of the pipe, reduce the silencer, etc., and emphasize that the competition will be more linear. Improve the characteristics of the linear exhaust pipe (due to the chassis interference, it is difficult to achieve true straightness), the path is shortened and the angle is smooth and the obstacle is reduced, but everyone should know that the shorter exhaust pipe is the pursuit of high turnover. Horsepower (low back pressure), slender type is good at low turning torque (high back pressure), the reason is that the pressure in the latter tube is high, the low and medium speed exhaust gas will be discharged very quickly, but the high speed will face the weakness of the blockage. However, the former has a problem of slow flow in the middle and low turn, but it can be smooth when it is turned to high exhaust.    Exhaust pipes based on the use of roads should actually choose a longer-length style as a condition for accumulating gas, and then the change in pipe diameter can take into account the performance of the full-speed domain, according to most people. According to the experience, the increase of the pipe diameter in the middle section is almost 10-15% better than the original factory (the engine is not modified), that is, the naturally aspirated engine is around 55-60, and the turbine engine is about 65-70. Of course, if your car's exhaust capacity is large enough, and after a heavy upgrade with the strength of 400hpover, then it is necessary to use more than 80 pipe diameter.    Regarding the arrangement of the pipe diameter, it is more suitable for those who value the torque, but it is suitable for people who value the torque. However, if you are the pursuer of the horsepower, it is suitable for the form of progressive enlargement. The design is to gradually expand the diameter of the pipe, so that the more rapid expansion to the rear, constitutes the exhaust gas speed increase, especially in the case of continuous high speed, which is also a trend of the current modified exhaust pipe .    Please note the resonance phenomenon in the catalyst/intermediate part    In the modification of the middle section exhaust pipe, there is also an important component that is the catalyst and the medium elimination. Although the basic function of the catalyst is to purify the exhaust gas, it has the same effect as eliminating the resonance sound, and is densely packed with many kinds of metals. The composition of the catalyst, according to the modification of the eyes, is indeed a major culprit hindering the smooth exhaust, but also a nasty hot spot, so many people will replace the shell type instead of the tube (straight tube is easy to cause resonance), often just this A small amount of straight through, you can feel the exhaust is much smoother, the sound will not be stuffy inside.Modification of the exhaust pipe, the medium elimination, the catalyst charge, will be done shorter and smaller, to improve the smoothness of the exhaust, but if some of the pipe diameter is too thick, this part will not shrink too much to ensure The power of low to medium. In addition, when you feel that the exhaust is too much and the torque is too much, you may be able to improve a lot of this phenomenon by knowing a so-called "cannonball".    Tail elimination internal structure partition plate and linear type    The tailpipe exhaust pipe, which is mainly used for muffling, is naturally a place where resistance is generated, which involves the design of the inside of the muffler. The structure of the tail elimination can be roughly divided into two categories. The first one is to reduce the low volume by means of a staggered partition to cause reflected waves. The original products are almost all secondary forms, and the second type is a linear type of sound absorbing cotton commonly used in the modification. From the standpoint of fluid mechanics, the baffle-type exhaust resistance must be large, and the horsepower boost is not as dominant as the linear one.    In order to reduce the exhaust obstruction of the tail elimination, it is not only necessary to straighten the passage and enlarge the diameter of the inner tube. It is necessary to miniaturize the entire silencer, and it is also possible to add some ingenuity, such as installing one before entering the tail elimination. The movable valve; or the infinitely designed double-loop accelerating airflow, so that the back pressure is reduced in view of the increase in the rotational speed. The purpose is a good workaround.    The straight line of the modified exhaust pipe tail, the noise absorption needs to be achieved by the muffler surface. In this case, most manufacturers use glass wool, but after a long time, the glass wool which is in a high heat environment for a long time will definitely be deteriorated. There are problems with resonance and loudening. Therefore, some products will now be marked with durable stainless steel wire. This is a perforated outer casing that is covered with stainless steel wire and then filled with glass wool. The stainless steel wire prevents heat from being transmitted to the glass wool, thereby extending the overall life.    Confirm preferences before modification    After reading the above instructions, you must confirm the characteristics you want before modifying the exhaust pipe. It is like replacing the exhaust pipe of Taitong with the self-discharge car. Otherwise, you will lose the low-turn torque. Even high-speed horsepower can't accumulate. In addition, judging whether the performance of an exhaust pipe is excellent or not, in fact, it is a good way to start from the sound. The condition that the exhaust gas is not smooth, the first thing is that the sound cannot be stuffed inside, but this does not mean that loud sound is a good phenomenon. If the sound is large but empty, it is not solid, it must be that its back pressure is too small, and the sound is full and thick exhaust pipe, which indirectly indicates that it can quickly discharge the exhaust gas, so the back pressure should be appropriate and correct.    ** It is worth noting that when you change, the resonance may be too large, and the exhaust pipe may be shaken left and right. At this time, ** replace the hardened lifting lug rubber (overweight) It is also necessary to crack the joint, and a well-designed exhaust pipe can be completed at a considerable cost. Under the premise that the engine has not been greatly modified, the effect of replacing only the exhaust pipe is unobtrusive. Nowadays, many people also replace the tail section of the exhaust gas and remove the three-way catalytic converter. This will definitely increase the emission of exhaust gas. We stand against the practice in the environmental protection position. Being able to grasp these principles, you will certainly enjoy the fun of modifying the exhaust.点击图标下载 App

  • Leopard selection Jaguar XE modified CGW valve exhaust

    Leopard selection Jaguar XE modified CGW valve exhaust

    Leopard selection Jaguar XE modified CGW valve exhaustFor a long time, the German luxury brand BMW 3 Series, Mercedes-Benz C-Class and Audi A4 have been the main players in the sports mid-size car market, and other products are difficult to compete with. With the launch of the Jaguar XE, with its young positioning, cool exterior design, and unspeakable sports talent, it has quickly attracted the attention of many consumers.This fledgling "sportsman" will directly target the BMW 3 Series as soon as it goes public. Everyone knows that the first few pioneers, especially the 3 series of modification cases, are endless, so the Jaguar XE, the little leopard, can finally get the acceptance of this part of the rider, and its own conversion potential is crucial.But to say that the modification is not alone, it can be explained by white. This has to be achieved by some brands to launch the corresponding modified parts. At present, the modified parts for XE are still relatively small, but it does not mean that there is no. CGW, a domestic first-line brand that has always had a keen insight and product development capability for the market, has recently launched a professional exhaust system for Jaguar XE.When it comes to the CGW brand, the modified fans will not be unfamiliar. Founded in 2009, the brand has been determined to become the leading brand of exhaust in China since its inception. Under the implementation of this concept, CGW has invested a lot in the research and development of exhaust products and the quality control of its products. Consumers bring high-quality exhaust products, and compared to the high price of some imported products, CGW's all this is achieved without the consumer having to invest too much.This Jaguar XE exhaust product uses the most popular controllable valve technology. When the valve is closed, the internal pressure of the exhaust gas will be formed, so that the vehicle can be lifted with low twist. When driving in the urban area, there is no need for the uncomfortableness of the breath due to the low twist loss, and the sound is very close to the original.

    Leopard selection Jaguar XE modified CGW valve exhaust

    Leopard selection Jaguar XE modified CGW valve exhaustFor a long time, the German luxury brand BMW 3 Series, Mercedes-Benz C-Class and Audi A4 have been the main players in the sports mid-size car market, and other products are difficult to compete with. With the launch of the Jaguar XE, with its young positioning, cool exterior design, and unspeakable sports talent, it has quickly attracted the attention of many consumers.This fledgling "sportsman" will directly target the BMW 3 Series as soon as it goes public. Everyone knows that the first few pioneers, especially the 3 series of modification cases, are endless, so the Jaguar XE, the little leopard, can finally get the acceptance of this part of the rider, and its own conversion potential is crucial.But to say that the modification is not alone, it can be explained by white. This has to be achieved by some brands to launch the corresponding modified parts. At present, the modified parts for XE are still relatively small, but it does not mean that there is no. CGW, a domestic first-line brand that has always had a keen insight and product development capability for the market, has recently launched a professional exhaust system for Jaguar XE.When it comes to the CGW brand, the modified fans will not be unfamiliar. Founded in 2009, the brand has been determined to become the leading brand of exhaust in China since its inception. Under the implementation of this concept, CGW has invested a lot in the research and development of exhaust products and the quality control of its products. Consumers bring high-quality exhaust products, and compared to the high price of some imported products, CGW's all this is achieved without the consumer having to invest too much.This Jaguar XE exhaust product uses the most popular controllable valve technology. When the valve is closed, the internal pressure of the exhaust gas will be formed, so that the vehicle can be lifted with low twist. When driving in the urban area, there is no need for the uncomfortableness of the breath due to the low twist loss, and the sound is very close to the original. The effect of the factory will not cause the consequences of disturbing the people. When the valve is opened, the low and thick exhaust sounds are instantaneously high, and the horsepower of the vehicle is completely vented. With the continuous increase of adrenaline, the title of the high-performance sports coupe is deserved.If you are the owner or prospective owner of Jaguar XE, and have a very good idea for car modification, please contact the merchant for advice:Jaguar XE mid-tail bilateral single-out valve exhaustAdd valve 8500No valve 4500Shanghai Hao Li Auto Parts Manufacturing Co., Ltd.Website: www.shcgw.cnAddress: No. 80, Jifeng Road, Minhang District, Shanghai

    Modification of exhaust high sound waves

    On the road, we whizzed past us, and there were more and more revamping cars. The high exhaust sound seemed to be one of the symbols of the modified car.Young people want to get more cars when they buy a car, but they are too discreet to overhaul the car engine system, and all relatively simple exhaust pipe modifications become theirs. So what do we usually say about the modification of the exhaust pipe?We generally refer to the exhaust system from the exhaust port connecting the combustion chamber, through the exhaust manifold, the middle section of the exhaust pipe to the end of the exhaust pipe, which is the entire exhaust gas discharge process. According to the four reciprocating motions of the car engine—intake, compression, work, and exhaust, if the exhaust system cannot quickly illuminate the exhaust gas after combustion, the next intake stroke must not be quickly and completely inhaled. Fresh air; especially the exhaust gas remaining in the combustion chamber at this moment, will also affect the next combustion efficiency, so that the power performance is naturally not ideal, which is the main purpose of modifying the exhaust system.It is the main method to modify the exhaust system by replacing the head, middle and tail sections of the original vehicle exhaust system to make the engine exhaust more smoothly and improve the power. Since 80% of the original head section is a large number of cast iron products, the inner tube is rough and the lengths of the manifolds are different. The joining method, distance and shape are also not enough, so it is very easy to generate exhaust. Interference phenomenon. If you change a banana head, this situation can be greatly improved.Exhaust pipe recommendedSpec titanium exhaustAspec titanium alloy exhaust has the characteristics of light weight, high strength, good corrosion resistance and high heat resistance. It still has high specific strength in the range of 150 °C ~ 500 °C, while the specific strength of aluminum alloy is obviously decreased at 150 °C. The corrosion resistance of titanium alloy is also much better than that of stainless steel. At the same time, because titanium alloys have a higher weight advantage, this means that the performance of the car can be further improved by lightweight means.Japan Aike Rui high performance exhaustARQRAY selects the material, shape and specifications of the * for each model. This careful selection allows the ARQRAY to be more versatile with the smoothness of the engine and exhaust. It allows 100% of the personality and strength of every ARQRAY-equipped vehicle. In addition, ARQRAY also considers the actual driving situation, achieving a rare balance between daily driving and good performance output, which can make your car have a habit suitable for you.Made of Japanese ** grade material, SUS304StainlessSteel stainless steel and titanium alloy material, through ARQRAY's superior craftsmanship, each product is like a work of art, presented to the world!
