The high flow downpipe is an essential upgrade for any turbocharged vehicle seeking to maximize its performance potential. In a factory exhaust system, the downpipe is often the most restrictive component due to its integrated catalytic converter, which hinders exhaust flow and increases backpressure. By replacing this with a high flow downpipe, you allow exhaust gases to exit the turbocharger more efficiently, reducing backpressure and kinetic energy loss. This leads to quicker turbo spool, reduced turbo lag, and a noticeable bump in horsepower and torque across the RPM range.
For vehicles with tuned engines, a high flow downpipe is even more critical. It enables the turbo to operate within its optimal efficiency zone, providing a more responsive and powerful driving experience. Moreover, the improved exhaust flow can positively affect fuel economy under normal driving conditions, as the engine works less to expel exhaust gases. When selecting a high flow downpipe, considerations include material quality, fitment, and emissions compliance. Our downpipes are crafted from T304 stainless steel, offering excellent corrosion resistance and thermal properties. We offer both catted and catless versions; catted versions utilize a high-flow catalytic converter, reducing emissions while maintaining performance, whereas catless versions are purely performance-oriented but may not pass emissions tests in certain regions. Therefore, choosing the right type depends on local regulations and your performance goals.
