The Audi RS6 and RS7 C8 combine luxury and brutal performance, but the factory exhaust keeps the 4.0L twin-turbo V8 far too restrained. The STRATEC Titanium Valved Cat-Back Exhaust System unlocks the engine’s true character—delivering a raw, motorsport-inspired soundtrack with the valves open and a refined, grand-touring tone with the valves closed.
Constructed entirely from lightweight titanium and engineered around a large cross-section integrated X-pipe, this system improves exhaust scavenging, throttle response, and sound clarity while remaining drone-free in both modes. For maximum volume and presence, it can be paired with optional free-flow front bypass pipes.
