Description
Unleash the full character of your BMW 8 Series (G14 Convertible / G15 Coupe / G16 Gran Coupe) M850i with the Fi Exhaust Valvetronic System, a perfect blend of precision engineering, acoustic performance, and OEM functionality.
This complete system includes the front pipe, mid X-pipe, and valvetronic muffler, all designed to retain your vehicle’s factory valve operation—no additional remote control required. The valves integrate seamlessly with BMW’s drive modes, delivering a composed note in Comfort and a deep, aggressive tone in Sport.
Expertly crafted from high-grade T304 stainless steel, this system reduces backpressure, improves exhaust flow, and enhances turbo response from the N63 twin-turbo V8. The X-pipe configuration equalizes exhaust pulses for a smoother flow and rich, balanced sound across the rev range.
