Valvetronic Equal Length Valved Sport Exhaust System - Stainless Steel - 4 Burnt Tips - 3.5 Outlet (BMW.F8X.M3.M4.VSES.BR.BRT) - 2015-2018 BMW M3 F80 / 2015-2020 BMW M4 F82-F83
The BMW F8X M3 and M4 deliver incredible performance from the factory, but the stock S55 exhaust tone has long been criticized for excessive rasp and a lack of depth. The Valvetronic Designs Equal Length Valved Sport Exhaust System was engineered specifically to transform the sound character of the S55 platform, eliminating much of the harsh factory tone while preserving the aggressive personality enthusiasts expect from an M car.
This complete cat-back system features a 2.75 inch equal-length H-pipe mid-section flowing into a high-performance 3.5 inch valved axle-back exhaust. The equal-length design helps smooth exhaust pulses for a cleaner, fuller tone with improved high-RPM clarity and reduced rasp. Constructed from premium T304 stainless steel, this system combines aggressive sound, improved flow characteristics, electronic valve control, and striking burnt exhaust tips for a more exotic appearance and driving experience.

Refined S55 Sound Without the Factory Harshness
Valvetronic Designs engineered this system to solve one of the biggest complaints surrounding the S55 platform: excessive rasp. The equal-length mid-section and H-pipe configuration dramatically improve exhaust pulse balance, delivering a smoother and deeper exhaust tone without losing the aggressive edge that makes the F8X platform exciting to drive.
With the valves open, the system produces a louder, freer-flowing exhaust note with sharper response and improved high-RPM clarity. With the valves closed, exhaust flow is routed through the quad-chamber muffler system for a quieter and more refined sound profile that is comfortable for daily driving and highway cruising.

Installation Notes
This exhaust system is designed as a true 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 sound quality, Valvetronic Designs recommends pairing the system with high-flow 200-cell catalytic converters.
