Manufacturer SKU: AUD.RSQ8.VSES.AG Audi RSQ8 Valved Cat-Back Exhaust System T304 Stainless Steel with OEM-Style Electronic Valve Control Overview The Audi RSQ8 blends supercar performance with SUV practicality—but like many modern performance vehicles, its factory exhaust keeps things a little too restrained. The Valvetronic Designs Valved Cat-Back Exhaust System unleashes the full potential of the 4.0L twin-turbo V8, giving it the voice it deserves. This 3-inch system runs from the downpipes to the OEM exhaust tips, offering two distinct personalities: valves closed for refined, factory-like cruising, or valves open for an unfiltered, aggressive soundtrack. For those who want even more performance and volume, our optional free-flow downpipes take things to the next level. Controlled via electronic standalone valves, the system offers long-term reliability, seamless integration, and unmatched flexibility. Why It Works - 3-Inch Diameter Tubing: Maximizes flow for improved throttle response and power. - Dual Sound Modes: Quiet refinement with valves closed, motorsport aggression with valves open. Sound & Control - Valves Closed: Stock-like sound levels for comfortable daily driving and highway cruising. - Valves Open: Silencer fully bypassed for maximum volume and character. - Optional Free-Flow Downpipes: Unlock even more performance and an enhanced exhaust tone.
