Valvetronic Equal Length Valved Sport Exhaust System - Stainless Steel - 4 Black Tips - 3.5 Outlet (BMW.F8X.M3.M4.VSES.BR.BLK) - 2015-2018 BMW M3 F80 / 2015-2020 BMW M4 F82-F83
The BMW F8X M3 and M4 are iconic performance platforms, but the factory S55 exhaust system leaves many enthusiasts wanting a deeper, smoother, and more refined sound. The Valvetronic Designs Equal Length Valved Sport Exhaust System was engineered specifically to eliminate much of the harsh factory rasp while unlocking the aggressive, balanced tone the S55 engine should have delivered from the factory.
This complete cat-back exhaust system features a 2.75 inch equal-length H-pipe mid-section flowing into a performance-focused 3.5 inch valved axle-back exhaust. The equal-length configuration smooths exhaust pulses throughout the RPM range, creating a cleaner and fuller sound while preserving the aggressive character enthusiasts love. Constructed from premium T304 stainless steel and finished with stealth-inspired black exhaust tips, this system combines improved sound quality, optimized exhaust flow, and electronic valve control in one complete package.

Balanced S55 Tone with Reduced Factory Rasp
Valvetronic Designs developed this exhaust system specifically to address the most common criticism of the S55 platform: excessive factory rasp. The equal-length H-pipe design balances exhaust pulses for a smoother, deeper, and more refined sound profile without sacrificing the aggressive tone expected from an M car.
With the valves open, the system delivers a louder, freer-flowing exhaust note with improved high-RPM clarity and a more motorsport-inspired character. Close the valves, and exhaust flow is routed through the quad-chamber muffler system for a quieter and more refined sound profile ideal for daily driving and highway cruising.

Installation Notes
This exhaust system is designed as a direct bolt-on upgrade utilizing factory mounting locations with no cutting or welding required. The system is fully reversible, allowing the vehicle to be returned to stock at any time.
For S55 applications running free-flow or race downpipes, some low-RPM rasp near 2,000 RPM may still be present during shifts. For the most refined overall tone, Valvetronic Designs recommends pairing the system with high-flow 200-cell catalytic converters.
