Experience the unmistakable sound and performance of Audi's legendary naturally aspirated V8 with the GCA Performance Valved Sport Exhaust System, engineered specifically for the 2010–2017 Audi RS4 and RS5 B8/B8.5 platform. Designed to replace the restrictive factory exhaust system, this premium cat-back upgrade improves exhaust flow, reduces back pressure, and allows the 4.2L V8 to perform at its full potential.
The optimized exhaust design promotes smoother exhaust scavenging and increased airflow, helping improve throttle response, engine efficiency, and power delivery throughout the RPM range. Whether you're carving through back roads or cruising on the highway, the system delivers a driving experience worthy of the RS badge.
Featuring electronically controlled exhaust valves and an included controller, drivers can choose between a refined, comfortable exhaust note for daily driving or an aggressive motorsport-inspired soundtrack that fully unleashes the character of Audi's iconic 4.2L V8.
