Valvetronic Designs - BMW F87 M2 Competition Equal Length Valved Sport Exhaust System
- Description
- Fitment
- Refund Policy
Overview
The S55 engine in the M2 Competition and M2 CS delivers exceptional performance, but its stock exhaust note leaves much to be desired—buzzy, raspy, and lacking the refined aggression enthusiasts expect. The Valvetronic Designs Equal-Length Valved Cat-Back Exhaust System solves this problem, unlocking the hidden character of the S55 while preserving the excitement and volume owners crave.
This system combines a 2.75-inch equal-length mid-section with an H-pipe and a 3.5-inch axle-back, delivering a smoother, richer tone across the rev range. With valves open, exhaust gases exit freely through the passenger-side tips for maximum presence. With valves closed, gases are routed through our quad-chamber muffler and driver-side tips, offering a quieter, more refined sound—perfect for daily driving.
Direct bolt-on fitment means installation is seamless, mounting to factory points without permanent modifications.
