Advantages of the product

Precision Engineered for Maximum Flow

Our high flow cat back exhaust system is engineered using advanced 3D scanning and digital modeling to ensure each component is optimized for maximum exhaust flow. This reduces backpressure, allowing your engine to breathe more freely, resulting in noticeable gains in horsepower and torque across the RPM range. The mandrel-bent tubing ensures smooth, consistent diameter, eliminating restrictions and improving overall exhaust efficiency. This precision not only boosts performance but also enhances fuel economy, making your drive more cost-effective and enjoyable.

Superior Material and Craftsmanship

Constructed from high-quality T304 stainless steel, our high flow cat back exhaust systems offer exceptional corrosion resistance and durability. Each system is meticulously welded and finished to meet rigorous quality standards, ensuring a long-lasting, rust-free performance. The use of precision CNC machining and robotic welding guarantees consistent quality and reliable fitment. This commitment to craftsmanship ensures your exhaust system not only performs at its best but also maintains an attractive appearance under the hood, reflecting the excellence of our manufacturing process.

Perfect Direct Bolt-On Fitment

We understand the importance of a hassle-free installation. Our high flow cat back exhaust systems are designed to be direct bolt-on replacements for your vehicle’s factory exhaust system. With factory-matching flanges and hangers, installation can be completed with basic hand tools and a jack, often without the need for cutting or welding. This saves you time and money in installation costs, allowing you to upgrade your exhaust system with confidence. Every system is rigorously tested to ensure precise fitment for the specific make and model, ensuring a seamless installation experience for enthusiasts and professionals alike.

A high flow cat back exhaust system is one of the most popular upgrades for car enthusiasts seeking improved performance and a more dynamic driving experience. Unlike a standard exhaust, which often has restrictive bends and narrow pipes, a high flow cat back exhaust system is designed to minimize backpressure and maximize exhaust gas flow. This is achieved through the use of mandrel-bent pipes, which maintain a constant inner diameter, reducing turbulence and ensuring smoother exhaust evacuation. When you install a high flow cat back exhaust system, your engine can expel exhaust gases more efficiently, which translates to better volumetric efficiency and, ultimately, increased horsepower and torque, especially in the higher RPM range. This improvement in gas flow also reduces the workload on your engine, which can lead to modest gains in fuel economy, provided you maintain consistent driving habits. Additionally, a well-designed cat back exhaust can improve the exhaust note, giving your car a deep, aggressive, and refined sound that reflects its performance capabilities. At CGW, we take pride in our manufacturing expertise. Our high flow cat back exhaust systems are developed using advanced 3D scanning and digital modeling technologies to ensure an exact fit for every vehicle model. This process involves capturing precise vehicle dimensions and exhaust routing, allowing us to engineer systems that align perfectly with factory mounting points and clear all suspension, drivetrain, and body components. Our independent mold processing workshop enables us to customize designs and produce components with remarkable accuracy and efficiency. The materials used in our exhaust systems are selected for optimal performance and longevity. We primarily use T304 stainless steel, which offers excellent corrosion resistance and heat tolerance. This ensures that your exhaust system remains in pristine condition even when exposed to harsh weather conditions and road salt. All welding is performed in a controlled environment, utilizing precision techniques to guarantee robust, leak-free joints. We also offer various finish options, including polished, brushed, or black coated, to match your vehicle’s aesthetic. When considering an upgrade to a high flow cat back exhaust system, it’s essential to check your local emissions regulations and ensure that your chosen system complies with them. Many high flow systems are designed to be compatible with factory catalytic converters and sensors, but it is always wise to verify compatibility. Our systems are developed to offer a balance between performance and daily drivability, with features such as valve controls or removable silencers in some models to allow you to fine-tune the sound volume. In conclusion, investing in a high flow cat back exhaust system is a reliable way to unlock your vehicle’s potential. With proper installation and maintenance, it will serve you well for many years, providing both functional and emotional rewards. Whether you’re on the street or the racetrack, the right cat back exhaust can genuinely transform your driving experience.

Frequently Questions

What exactly is a high flow cat back exhaust system?

A high flow cat back exhaust system replaces your vehicle’s exhaust components from the catalytic converter back (the cat-back section), including the intermediate pipes, muffler, and tailpipe. It is engineered with larger diameter, mandrel-bent tubing and free-flowing mufflers to reduce exhaust backpressure, which aids in improving engine performance and producing a more aggressive exhaust note.
Depending on your vehicle and other modifications, a high flow cat back exhaust can add anywhere from 5 to 15 horsepower and similar amounts of torque. The exact gain depends on the vehicle, the restrictiveness of the factory exhaust, and the design efficiency of the aftermarket system. For best results, combining the exhaust with other bolt-on upgrades like an intake or a tune can yield higher cumulative gains.
Yes, our high flow cat back exhaust systems are specifically designed for various makes and models using 3D scanning and digital modeling. Each system is manufactured to be a direct bolt-on that matches all factory hangers and connections, ensuring a perfect fitment without the need for modifications. This makes installation straightforward and trouble-free, often allowing DIY enthusiasts to install the system in a few hours.
No, installation is relatively straightforward for most DIY enthusiasts. Our systems come with all necessary hardware and gaskets, and the design is such that you can often install it with basic hand tools and a jack or ramps. However, if you’re not comfortable working on your vehicle, it’s recommended to have a professional exhaust shop handle the installation to ensure optimal mounting and alignment.
Our high flow cat back exhaust systems are designed to provide a sporty sound that is aggressive under throttle but not overly obnoxious during highway cruising. Sound levels vary by model; some include features like resonators or optional silencers to allow you to adjust the volume and tone. We also offer systems with acoustic tuning to minimize drone inside the cabin, ensuring a comfortable driving environment. Check the product specifications for dB ratings and sound clips to select the right system for your preference.
