Fi Exhaust Single Front-Mid Pipe + Valvetronic Muffler + Quad Silver Tips (Retains OEM Valve Settings - No Remote) - F80 M3 | F82 M4 2014-2020
Unlock the true personality of your S55-powered BMW F80 M3 or F82 M4 with the Fi Exhaust Single Front–Mid Pipe + Valvetronic Muffler system. Designed to eliminate the restrictive factory layout, this upgrade delivers a fuller, deeper, and more aggressive exhaust tone that transforms your driving experience — all while maintaining seamless OEM valve control.
The streamlined single front–mid pipe smooths exhaust flow and reduces turbulence, giving the S55 engine a richer note with improved throttle response. Paired with Fi’s precision-engineered Valvetronic muffler, the system allows you to switch instantly between quiet and aggressive modes using your factory drive settings — no remote, coding, or extra electronics required.
With the valves closed, the exhaust stays refined and neighbor-friendly. Open the valves, and the car unleashes a sharp, exotic, motorsport-inspired soundtrack with enhanced turbo spool and a cleaner high-RPM scream. The included Quad Silver Tips complete the upgrade with a bold visual statement worthy of an M car.
Hand-crafted from high-grade T304 stainless steel, TIG-welded, and engineered for perfect fitment, this system is built to handle both street and track use while maintaining long-term durability.
Whether your M3/M4 is stock or tuned, the Fi system elevates both sound and performance, letting the S55 engine finally breathe — and be heard — the way it should.
