The Milltek SSXAU190 is a performance Cat-Back exhaust system engineered to replace the factory setup on the Audi B8 S5 4.2 V8 Coupe. Constructed from premium 304L "Aircraft" Grade stainless steel, this exhaust system is built for longevity and resistance to harsh environmental conditions. The 2.36" (60.00mm) pipe diameter is intended to improve exhaust flow, potentially leading to increased horsepower and torque. This particular Milltek Cat-Back exhaust system is exclusively for manual transmission models. It fits the Audi S5 B8 (2009-2016) with the 4.2L V8 engine. Ensure your vehicle is a manual transmission to confirm compatibility.
