Audi RSQ8 4.0L Catback, T304 SS Anodized Gold, Reuses OEM Tips

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 standalone electronic valves, the system offers long-term reliability, independent operation, and unmatched flexibility.

• T304 stainless steel for long-term durability and corrosion resistance finished in Anodized Gold
• 3-Inch Diameter Tubing: Maximizes flow for improved throttle response and power.
• Electric valves with standalone controller
• Weight Savings: 11.5 lb lighter than the factory exhaust.
• Tips: Designed to retain OEM exhaust tips for a factory-fit appearance.
