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.

Why It Works

Full Titanium Construction: Major weight reduction with excellent heat dissipation
Large Cross-Section X-Pipe: Enhances scavenging for a cleaner, sharper exhaust tone
Complete Cat-Back System: Designed as a cohesive setup for consistent sound and fitment

Sound & Control

Valves Open: Full-bodied V8 aggression with strong midrange and a sharper top-end note
Valves Closed: Subtle, composed exhaust tone ideal for daily driving and highway cruising
Electronic Valve Control: Instant sound adjustment from the driver’s seat
Optional Bypass Pipes: Unlock maximum volume and presence
