Unleash the true sound and performance potential of your BMW F90 M5 with the Fi Exhaust Front Pipe + Mid X-Pipe + Valvetronic Muffler + Quad Silver Tips—a premium bolt-on system engineered specifically for the 4.4L Twin-Turbo S63 engine. Designed to retain all OEM valve settings with no remote required, this system delivers an elevated driving experience while preserving full factory comfort and control.
The upgraded front pipe and mid X-pipe dramatically improve exhaust flow by reducing backpressure and balancing exhaust pulses, resulting in quicker turbo spool, sharper throttle response, and enhanced mid-range torque. When the valves are closed, the system maintains refined, OEM-like quietness. With the valves open, your F90 M5 transforms—deep, aggressive, and unmistakably V8.
The Fi Valvetronic muffler is constructed from high-grade stainless steel with precision TIG welds for maximum durability under extreme heat cycles. A set of bold quad silver tips completes the package with a clean, motorsport-inspired finish that elevates the rear aesthetics of your M5.
Installation is fully bolt-on, utilizing factory mounting points, and integrates seamlessly with BMW’s drive modes, including Comfort, Sport, Sport+, and M Modes.
