V2 T304 Stainless Steel Vacuum-Operated Valves

Overview

Version 2 of the Valvetronic Designs E9x M3 Valved Sport Exhaust System delivers significant improvements in sound and performance for the BMW E9x M3. Constructed from premium brushed T304 stainless steel and fully mandrel-bent for smooth flow, the system is available as a valved rear section or as a complete system with an optional X-pipe.

Sound & Control

With the valves closed, the exhaust maintains factory-like refinement for urban driving and long-distance cruising.

With the valves open, the M3 delivers an aggressive, motorsport-inspired V8 tone with sharp throttle response.

Choose the rear section only or a complete system with a free-flow or catted X-pipe.
