Fi Exhaust Front Pipe + Mid X-Pipe + Valvetronic Muffler (Retains OEM Valve Settings - No Remote) - G14/ G15/ G16 M850i 2019-Up

Unleash the full potential of your BMW M850i (G14 Convertible / G15 Coupe / G16 Gran Coupe) with the Fi Exhaust Valvetronic System, engineered for precision sound, performance, and factory-level integration.

This complete exhaust upgrade includes the front pipe, mid X-pipe, and valvetronic muffler, designed to retain your OEM valve control without the need for an external remote. The system integrates perfectly with BMW’s drive modes, producing a refined tone in Comfort mode and an aggressive, resonant growl in Sport mode.

Constructed from premium T304 stainless steel, the Fi system optimizes exhaust flow and reduces backpressure, enhancing throttle response and turbo efficiency from the N63 twin-turbo V8. The precision-tuned X-pipe balances exhaust pulses for smoother flow, reduced drone, and a rich, motorsport-inspired tone.
