Valvetronic Equal Length Valved Sport Catback Exhaust System - BMW M2 Competition (F87) 2019-2021
Lease for as low as $/week
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.
Why It Works
-
Equal-Length Mid-Section: Balances exhaust pulses for a smoother, more pleasant tone without sacrificing aggression.
-
H-Pipe Integration: Improves exhaust scavenging for a fuller, richer sound.
-
Dual Sound Modes: Enjoy raw, motorsport tone (open) or comfortable refinement (closed).
Sound & Control
-
Valves Open: Aggressive, free-flowing tone with improved top-end character.
-
Valves Closed: Stock-like volume and tone for discreet driving.
-
Electronic Valve Control: Includes remote controller; OEM valve integration optional.
