Free up your Audi C8 RS6 or RS7's 4.0T twin-turbo V8 with these EPA-compliant 400 cell high-flow catted downpipes, built to reduce backpressure and unlock a deeper exhaust tone while maintaining emissions compliance standards.
The C8 RS6 and RS7 pair executive refinement with supercar-level performance, but the factory catalysts restrict exhaust flow and mute the engine's character. These EPA-compliant 400 cell high-flow catted downpipes reduce backpressure, enhance turbo efficiency and bring out a deeper, more commanding tone, all while maintaining emissions compliance standards. They form the foundation of serious 4.0T performance.
