APR Catback Exhaust System - Audi RS6 / RS7 (C8)

Introducing the APR Catback Exhaust System for the Audi C8 RS6 and RS7

The APR Catback Exhaust System for the Audi C8 RS6 and RS7 is a complete, high-performance exhaust solution that runs the entire length of the vehicle from the catalyst back. This system is engineered to boost performance, elevate sound, and enhance aesthetics with RS-style diamond black oval exhaust tips that are sure to make a statement. Crafted from premium materials and built with advanced manufacturing techniques, this system is designed to withstand harsh conditions and deliver lasting performance. Expect a bold, aggressive growl at wide-open throttle, along with an impressive gain of 9 horsepower and 16 FT-LBS of torque to all four wheels!

Unmatched Design and Precision Engineering  

The APR system includes downpipes extending to the factory catalyst in the upper engine bay, making this a true full-system upgrade. We’ve minimized restrictions with smooth transitions, cast inlets, oversized piping, and straight-through mufflers and resonators. Constructed from mandrel-bent T304 stainless steel with a brushed finish and TIG welding throughout, this exhaust system is as durable as it is striking. Installation is hassle-free, thanks to precision-fit brackets and OEM-style slip clamps.

RS Performance  

The entire system is increased to a dual 3” (72mm) exhaust path. With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips. When exhaust gasses travel into the multichambered rear muffler / resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequencies without restricting flow on the open-valve path. With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5” (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed. Finally the system terminates via oversized 8.23”x4.76” (211x21mm) RS-style oval exhaust tips. The tips feature a diamond black finish and a subtle APR logo for a refined touch.
