Description

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 extensive R&D on B58-powered platforms, this system transforms the Z4’s sound and performance, unlocking the true potential of BMW’s celebrated inline-six. It features brushed T304 stainless steel, a single 3.5-inch midsection transitioning into dual 3-inch mandrel-bent runs for optimal exhaust scavenging and reduced backpressure, and electronic-actuated valves for rapid and reliable operation. This system is 11.1 lbs lighter than the factory exhaust and includes a valved catback exhaust system, valve controller kit, and brushed Valvetronic tips. It offers direct bolt-on installation as a cat-back replacement to OEM mounting points.

Key details include a maximum flow design for optimal exhaust scavenging and reduced backpressure, a balanced sound profile tuned for a deep, full-bodied note inspired by acclaimed B58 Supra and M340i systems, and precision construction using TIG-welded T304 stainless steel for exceptional durability and corrosion resistance.
