Unlock a sharper, more aggressive exhaust tone and improved flow with the Fi Exhaust Front Pipe + Mid X-Pipe + Valvetronic Muffler + Quad Silver Tips for the BMW F97 X3M / F98 X4M. Designed specifically for the high-output 3.0L Twin-Turbo S58, this system delivers a noticeable upgrade in sound, responsiveness, and overall driving excitement—while seamlessly retaining full OEM valve functionality without the need for an external remote.

The free-flowing front pipe and mid X-pipe work together to smooth exhaust pulses and reduce turbulence, resulting in faster turbo spool, stronger mid-range torque, and a richer, more dynamic exhaust note. When the factory valves close, you retain the refined, quiet mode ideal for daily driving. Open the valves and the system unleashes a deeper, more resonant tone that brings the S58 engine to life.

Crafted from premium stainless steel and precision TIG-welded, the Valvetronic muffler ensures exceptional durability even under high-heat, high-load conditions. The included quad silver tips provide a bold, motorsport-inspired finish that enhances the rear aesthetics without altering factory fitment.

This setup is fully bolt-on, utilizes OEM mounting points, and maintains compatibility with the vehicle’s factory valve settings—including Comfort, Sport, and Sport+ drive modes.
