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.

Beautifully made

"For the price, this is a great value for a full stainless x-pipe with a resonator. Paired with the valved muffler you can't go wrong. Would be neat if we could ask for a change like an extra bung welded on from factory (for a wideband)."

— Peter D. (5/5)

Great investment

"At first I was disappointed because the quality of the sound of my car went down but as soon as I was able to let it rev out I was amazed by how much bettter and more aggressive it sounded I drove it through the tunnels at my baldy and it made my car scream like never before 10/10 best sounding v8 by far"

Perfect Tone

"Perfect tone! The best way to unlock the s65 just a little bit more without disrupting the town next to yours. Deep low down and screams up top! The perfect combo. The only thing that would make this setup better is adding the valved mufflers ;)"

Q&A

Will there be an engine warning light when I install and if so is there a way to get rid of it?
If the CEL illuminates, it can be addressed by adding spacers or a tune.
Will my car need to be tuned with either one?
It is recommended to have it tuned or use O2 spacers for these systems.
