BMW G29 Z4 M40i Valved Sport Exhaust System

That’s why we’ve engineered the perfect exhaust setup to elevate both the performance and sound of your Z4 to an entirely new level.

Engineered for the Ultimate Sound Experience

Our exhaust system features a single 3 1/2-inch midsection, seamlessly transitioning into a dual 3-inch configuration all the way to the exhaust tips. This optimized layout significantly improves exhaust flow, enhancing both throttle response and overall engine performance. But it’s not just about power—it’s about delivering the perfect soundtrack. Inspired by our work on the legendary B58 Supra and the M340i, we’ve meticulously tuned the system to deliver a rich, aggressive tone that’s powerful on the throttle yet refined when cruising. The result? A full-bodied exhaust note that matches the performance of your BMW.
