The 034Motorsport Res-X High-Flow Midpipes for the Audi TTRS 8S & RS3 8.5V Quattro unleash a throaty growl under hard acceleration that exudes the sound of performance and warns bystanders that this isn't your average 5-cylinder. The new aggressive exhaust note is accomplished by removing the secondary catalytic converters and replacing them with the ready-to-install 034Motorsport Res-X High-Flow Midpipes. The primary catalytic converter is retained to reduce the majority of exhaust emissions.

NOTE: this product will not fit vehicles with gasoline particulate filters (GPF).
