BMW E9X M3 Valved Exhaust System – V2
T304 Stainless Steel with Vacuum-Operated Valves & Optional X-Pipe
Overview
Version 2 of the Valvetronic Designs E9X M3 Valved Exhaust System delivers significant upgrades in both reliability and sound refinement, making it the benchmark choice for the platform. We’ve returned to vacuum-actuated valves—proven to be more durable and consistent than electronic alternatives—and enhanced the exhaust tuning for a purer, more engaging driving experience.
Constructed from premium brushed T304 stainless steel and fully mandrel-bent for maximum flow, this system offers the flexibility to cruise quietly with valves closed or unleash the raw S65 V8 soundtrack with valves open. For too long, premium valved systems have been out of reach for many enthusiasts—our mission has been to change that.
For even greater performance and sound, pair the valved rear section with our high-performance X-pipe mid-sectio, available in both free-flow and catted configurations.
Why It Works
-
Vacuum-Actuated Valves: Increased reliability and rapid response for seamless sound control.

High-Flow Mandrel-Bent Tubing: Improves throttle response and overall power delivery.

Mid-Pipe Options

Free-Flow X-Pipe: Aggressive tone and maximum horsepower gains; features a large X-merge after the transmission tunnel for optimal scavenging.

Four resonators in the front section smooth exhaust tones immediately from the engine.
