Performance Benefits

Upgraded downpipes allow the turbocharger(s) to spool up faster and maintain more boost than stock downpipes, resulting in increased power output and better overall engine performance. This upgrade also improves throttle response, and provides a more responsive and powerful driving experience.

Enhanced Exhaust Flow and Reduced EGTs:

High flow cats are designed to allow exhaust gases to pass from the engine and turbos more freely compared to stock catalytic converters, resulting in a reduction of backpressure and a reduction in exhaust gas temperatures (EGTs).

The use of mandrel bent tubing ensures smooth exhaust flow post-cat, which maintains reduced back pressure and exhaust gas temperatures (EGTs) for optimal performance.

Better Flow = Faster Spool = More Boost:

Reduction of EGTs and decreased backpressure allows turbocharger(s) to operate more efficiently in terms of spool time and building boost.

Build Quality:

High-Quality T304 Stainless Steel

Downpipes constructed from 304 stainless steel offer superior durability and resistance to corrosion, ensuring long-lasting performance.
