BMW G01 X3 M40i Valvetronic Designs Valved Exhaust System

Unleash the Full Potential of Your B58

Overview

At Valvetronic Designs, we believe enthusiasts deserve the ultimate driving and sound experience. Thats why 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 utilizes the maximum possible piping diameter to unlock a raw, unfiltered sound when the valves are open. The result? Explosive turbo spool, aggressive overrun, and an addictive tone that sings from idle to redline.

Sound & Control

This system is designed for complete versatility:

• 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 M40is 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.
