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
