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 OEM-style electronic valves, the system offers long-term reliability, seamless integration, and unmatched flexibility.
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.
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.
Material: Signature T304 stainless steel for strength and corrosion resistance.
Weight Savings: 11.5 lb lighter than the factory exhaust.
Craftsmanship: Precision TIG welds for durability and premium finish.
Tips: Designed to retain OEM exhaust tips for a factory-fit appearance.

Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
