Valvetronic Equal Length Valved Sport Exhaust System - Stainless Steel - 4 Brushed Steel Tips - 3.5 Outlet (BMW.F8X.M3.M4.VSES.BR.BRSH) - 2015-2018 BMW M3 F80 / 2015-2020 BMW M4 F82-F83
The BMW F8X M3 and M4 are legendary performance platforms, but many enthusiasts agree the factory S55 exhaust note lacks the depth and refinement expected from an M car. The Valvetronic Designs Equal Length Valved Sport Exhaust System was engineered specifically to solve the harsh rasp and uneven tone that plague the factory setup, delivering a smoother, deeper, and far more exotic exhaust character throughout the RPM range.
This complete cat-back system features a 2.75 inch equal-length H-pipe mid-section feeding into a high-flow 3.5 inch valved axle-back exhaust. The equal-length design balances exhaust pulses to dramatically improve tone quality while maintaining the aggressive personality enthusiasts want from the S55 platform. Constructed from premium T304 stainless steel, this system combines durability, improved flow, reduced rasp, and complete electronic valve control with aggressive brushed steel exhaust tips for a clean OEM-plus appearance.

The S55 Exhaust Tone BMW Should Have Built
Valvetronic Designs engineered this system specifically to eliminate the excessive rasp commonly associated with the S55 platform while preserving the aggressive character that makes the F8X chassis so exciting to drive. The equal-length mid-section and H-pipe configuration help smooth exhaust pulses for a cleaner, fuller tone with improved high-RPM clarity and noticeably reduced harshness.
With the valves open, the system delivers a louder, more aggressive exhaust note with freer exhaust flow and a sharper motorsport-inspired character. Close the valves, and the quad-chamber muffler routes flow through the driver-side exhaust outlets for a far more refined and comfortable tone suitable for everyday driving.

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