The C8 RS6/RS7 pairs long-distance comfort with serious pace—but the factory exhaust keeps the 4.0L twin-turbo V8 far too quiet. The Valvetronic Designs Titanium Valved Cat-Back transforms the experience, delivering a raw, motorsport-inspired soundtrack with the valves open, and a refined, grand-touring tone with the valves closed.
Crafted entirely from titanium and engineered around a large cross-section H-pipe, this system improves exhaust scavenging and throttle response while staying drone-free in either mode. For maximum presence and performance, pair it with our free-flow front bypass pipes.
Note: Valve simulators are recommended on this platform to prevent CELs related to factory valve monitoring. Contact our support team for guidance.
Titanium Construction: Significant weight reduction and rapid heat dissipation for sharper response.
Large Cross-Section X-Pipe: Enhances scavenging for a cleaner, more exotic tone.
Full-System Tuning: Designed as a cohesive cat-back for consistent sound quality and fitment.
Valves Open: Full-bodied V8 aggression, pronounced midrange, and a sharper top-end note.
Valves Closed: Subtle, composed tone ideal for daily use and highway cruising.
Bypass Pipes (Optional): Unlock maximum volume and presence when combined with the cat-back.
Material: Lightweight titanium throughout.
Weight Savings: 61.5 lb lighter than the factory exhaust.
Craftsmanship: Precision TIG welds and smooth, high-flow routing for durability and performance.
Tips: Premium tips designed to complement the RS6/RS7 rear aesthetics.

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.
NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
