JHM 3" Performance (RACE) Cat-back Exhaust with OEM Valve System for C7 S7 4.0T IS NOW AVAILABLE!

 

This meticulously crafted exhaust system is tailored to deliver unparalleled power gains and a thrillingly aggressive exhaust note, while preserving the factory OEM Exhaust Valve technology to ensure an authentic Audi driving experience.

 

 

 Crafted from premium-grade stainless steel, the JHM Exhaust 3" Performance Cat-Back is built to deliver superior performance. Its mandrel-bent piping ensures optimal exhaust flow and minimized backpressure. The innovative valved design not only enhances performance but also retains the factory-style exhaust valves for a comfortable, OEM+ feel without any compromise on performance.

 

Why 3" Inch piping diameter? Through extensive research, calculations, and testing, we have determined that the optimal piping diameter for the 4.0T engine is 3 inches. Anything smaller would restrict exhaust flow and result in choking the engine's turbos, hindering performance. Our findings have been carefully considered in the development of our exhaust system to ensure maximum efficiency and power output for your vehicle.
