BMW’s move from the S85 V10 to the S63 twin-turbo V8 brought big gains in efficiency and speed—but the factory exhaust left the soundtrack behind. The Valvetronic Designs Valved Exhaust System restores the drama, delivering a sharper, more engaging tone with genuine GT composure when you want it.
Connecting to OEM or aftermarket free-flow downpipes, this system runs 3.0 inches from inlet to outlet and features a large X-pipe crossover for superior scavenging and response. Exhaust flow then passes through our valved mufflers, exiting via your choice of premium tips. A vacuum-actuated valve system with included controller ties into the factory harness for full, on-demand sound control.
Large X-Pipe Crossover: Enhances scavenging for improved mid-range punch and a cleaner, more harmonized tone.
3.0" Mandrel-Bent Tubing: Reduces back pressure and sharpens throttle response.
Vacuum-Operated Valves: Proven durability and rapid actuation for seamless sound transitions.
Valves Closed: Refined, near-OEM volume for daily driving and highway cruising.
Valves Open: Deep, assertive V8 character with a motorsport edge.
Controller Integration: Key fob control plugs into factory valve circuitry for reliable operation and complete control.
Materials: T304 stainless steel or ultra-light Grade 5 titanium.
Weight Savings vs. OEM: –21.7 lb (Stainless) / –54.8 lb (Titanium).
Craftsmanship: Precision TIG welds; smooth, high-flow routing.
Tips: Multiple finishes available to complement your M5.

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.
