Valvetronic Designs Equal Length Valved Exhaust System – BMW F87 M2 Competition / M2 CS

Transform the S55 Sound with True Equal-Length Performance

Unlock the sound the S55 should have had from factory with the Valvetronic Designs Equal Length Valved Cat-Back Exhaust System for the BMW F87 M2 Competition and M2 CS. Designed to eliminate the harsh rasp and buzzy tone commonly associated with the S55 platform, this system delivers a deeper, smoother, and more exotic exhaust note while retaining aggressive character under load.

Featuring a 2.75” equal-length mid-section with integrated H-pipe and a 3.5” valved axle-back section, this system offers the perfect balance between daily comfort and motorsport aggression. With valves open, exhaust gases flow unrestricted for maximum volume and performance. With valves closed, gases are routed through the quad-chamber muffler for a refined, OEM-like driving experience.

Available in T304 stainless steel or ultra-lightweight Grade 5 titanium.
