The Valvetronic Designs Valved Axle-Back for the BMW G2X platform brings the next evolution in sound customization. Inspired by our renowned F-Chassis systems, this setup offers the flexibility to run OEM valve integration, pair with additional exhaust modifications, or enjoy as a standalone upgrade—all without compromising on fit, finish, or tone.
TIG-welded from T304 stainless steel and designed to utilize factory mounting points and cut locations, the system delivers an OEM+ installation and appearance, with 3.5" tips perfectly filling the rear bumper.
Valves Closed: All exhaust gases route through our precision-engineered quad-chambered muffler, delivering stock-level volume for early morning starts, stealthy commuting, and drone-free cruising.
Valves Open: The muffler is bypassed entirely, freeing the exhaust flow for a deeper, more engaging tone without unwanted cabin drone.
Whether you keep your exhaust otherwise stock or pair it with free-flow components, the system adapts to deliver a driving soundtrack tailored to you.
True OEM+ Fitment: Factory mounting points and cut locations for seamless installation.
Customizable Sound: Works perfectly as a standalone upgrade or part of a full exhaust build.
OEM Valve Integration: Operates through your BMW’s drive modes for instant control

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.
