Audi C8 RS6,RS7 4.0L Catback Grade 5 Titanium

The C8 RS6/RS7 pairs long-distance comfort with serious pace—but the factory exhaust keeps the 4.0L twin-turbo V8 far too quiet. The Valvetronic Designs Titanium Valved Cat-Back transforms the experience, delivering a raw, motorsport-inspired soundtrack with the valves open, and a refined, grand-touring tone with the valves closed. Crafted entirely from titanium and engineered around a large cross-section X-pipe, this system improves exhaust scavenging and throttle response while staying drone-free in either mode. For maximum presence and performance, pair it with our free-flow front bypass pipes.

• Grade 5 Titanium
• Rapid-actuating electronic valves
• 61.5 lb lighter than the factory exhaust.
• Premium tips designed to complement the RS6/RS7 rear aesthetics.
• Grade 5 Titanium construction for maximum weight savings and strength
