# Title: Valved Catback Exhaust System for Audi RS6 RS7


## Description: 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 Construction & Details Material: Full titanium throughout Weight Savings: Approx. 61.5 lbs lighter than factory exhaust Craftsmanship: Precision TIG welding and smooth, high-flow routing Exhaust Tips: Premium tips designed to complement RS6/RS7 rear styling Vehicle Fitment 2019–2025 Audi RS6 Avant (C8) 2019–2025 Audi RS7 Sportback (C8) Installation Notes Direct bolt-on cat-back replacement Valve simulators recommended to prevent valve-related CELs 100% reversible — return to stock at any time
