The Valvetronic Designs Valved Exhaust System for the BMW G29 Z4 M40i is the ultimate upgrade for enthusiasts who demand both performance and versatility. Developed from our extensive R&D on B58-powered platforms—including the Supra and M340i—this system transforms the Z4’s sound and performance, unlocking the true potential of BMW’s celebrated inline-six. Maximum Flow Design: Single 3.5" midsection transitioning into dual 3" mandrel-bent runs for optimal exhaust scavenging. Balanced Sound Profile: Tuned for a deep, full-bodied note inspired by our acclaimed B58 Supra and M340i systems.
