E9x M3 Valvetronic Designs X-Pipe Midpipe
Maximum Flow. Maximum Sound. Maximum Performance.
Overview
The E9x M3 is already a legend, but if you’re chasing the ultimate combination of sound and performance, our Valvetronic Designs X-Pipe Midpipe is your answer. This isn’t your average midpipe—engineered from the ground up, it features a free-flow X merge positioned just after the transmission tunnel and 4 resonators to optimize exhaust scavenging and unlock horsepower gains throughout the entire rev range.
Design & Sound Engineering
-
Quad Resonator Setup: Two front resonators to reduce rasp, followed by dual 12-inch rear resonators to smooth exhaust tones and refine the overall sound profile.
-
Optional Catted Version: For those seeking a balance of flow and refinement, our 200 CELL EURO 6 certified catalytic converters provide exceptional quality and performance while keeping volume levels in check.
-
Performance-Tuned X Merge: Improves scavenging, boosts mid-range torque, and delivers a sharper throttle response.
Whether you choose the fully free-flow version for maximum aggression or the catted version for a more refined experience, this X-pipe is built for those who demand the most from their M3—both in sound and in performance.
