Description:

The Audi C8 RS6 and RS7 combine executive refinement with supercar-level performance, powered by the formidable 4.0T twin-turbo V8. While factory catalysts restrict exhaust flow and mute the engine’s full character, Valvetronic’s NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, enhance turbo efficiency, and unlock a deeper, more commanding exhaust tone — all while maintaining emissions compliance standards. This upgrade forms the foundation of serious 4.0T performance.
