Unleash the full potential of your BMW G01 X3 M40i's B58 with the Valvetronic Designs valved exhaust system, built around a 3.5-inch midpipe for maximum flow.
Our pursuit of perfection for the G01 platform has resulted in one of our finest exhaust systems to date. Engineered using lessons from our most successful designs, this system uses the maximum possible piping diameter to unlock a raw, unfiltered sound when the valves are open: explosive turbo spool, aggressive overrun and an addictive tone that sings from idle to redline.
Sound and control
- Valves open: full-throttle excitement with unrestrained volume and character
- Valves closed: refined and quiet, ideal for daily driving or early morning starts
With over 25 dB of difference between modes, you have complete control over your M40i's soundtrack thanks to the included standalone valve controller.
Performance benefits
Beyond the sound, this exhaust delivers improved exhaust flow, contributing to sharper throttle response and enhanced driving dynamics. The precision-engineered 3.5-inch midpipe ensures maximum flow for the B58 engine to breathe freely.
