The E9x M3 is already a legend, but if you’re chasing the ultimate combination of sound and performance, our Valvetronic Designs X-Pipe Midpipe is your answer. This isn’t your average midpipe—engineered from the ground up, it features a free-flow X merge positioned just after the transmission tunnel and 4 resonators to optimize exhaust scavenging and unlock horsepower gains throughout the entire rev range.
Quad Resonator Setup: Two front resonators to reduce rasp, followed by dual 12-inch rear resonators to smooth exhaust tones and refine the overall sound profile.
Optional Catted Version: For those seeking a balance of flow and refinement, our 200 CELL EURO 6 certified catalytic converters provide exceptional quality and performance while keeping volume levels in check.
Performance-Tuned X Merge: Improves scavenging, boosts mid-range torque, and delivers a sharper throttle response.
Whether you choose the fully free-flow version for maximum aggression or the catted version for a more refined experience, this X-pipe is built for those who demand the most from their M3—both in sound and in performance.

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.
