Valvetronic Equal Length Valved Sport Exhaust System - Stainless Steel - 4 1x1 Carbon Fiber Tips - 3.5 Outlet (BMW.F8X.M3.M4.VSES.BR.RC) - 2015-2018 BMW M3 F80 / 2015-2020 BMW M4 F82-F83
The BMW F8X M3 and M4 are serious performance machines, but the factory S55 exhaust note often leaves enthusiasts wanting a smoother and more refined sound profile. The Valvetronic Designs Equal Length Valved Sport Exhaust System was engineered specifically to eliminate much of the factory rasp while unlocking the balanced, aggressive tone the S55 platform was always capable of producing.
This complete cat-back exhaust system features a 2.75 inch equal-length H-pipe mid-section paired with a high-flow 3.5 inch valved axle-back exhaust. The equal-length configuration smooths exhaust pulses throughout the RPM range for a deeper, cleaner, and more exotic sound without sacrificing aggression. Constructed from premium T304 stainless steel and finished with aggressive 1x1 carbon fiber exhaust tips, this system delivers improved acoustics, enhanced exhaust flow, and full electronic valve control in a premium motorsport-inspired package.

Balanced S55 Acoustics with Exotic Character
Valvetronic Designs engineered this system to solve one of the most common complaints surrounding the S55 engine: excessive factory rasp. The equal-length H-pipe layout improves exhaust pulse balance, creating a smoother and fuller sound profile with enhanced high-RPM clarity and significantly reduced harshness.
With the valves open, the system delivers a louder and more aggressive exhaust note with freer exhaust flow and a sharper motorsport-inspired tone. Close the valves, and exhaust gases are routed through the quad-chamber muffler system for a quieter and more refined sound profile ideal for daily driving and long highway trips.
