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 H-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.

Note: Valve simulators are recommended on this platform to prevent CELs related to factory valve monitoring. Contact our support team for guidance.

Why It Works

• Titanium Construction: Significant weight reduction and rapid heat dissipation for sharper response.

• Large Cross-Section X-Pipe: Enhances scavenging for a cleaner, more exotic tone.

• Full-System Tuning: Designed as a cohesive cat-back for consistent sound quality and fitment.
