Unlock the full sound and performance of your BMW G80 M3 / G82 M4 with the Fi Exhaust Front Pipe + Mid X-Pipe + Valvetronic Muffler + Quad Silver Tips (M-Performance Version)—engineered specifically for the 3.0L Twin-Turbo S58 powerplant. This premium exhaust system seamlessly retains all OEM valve settings, giving you factory drive-mode integration with a significantly enhanced tone.

The upgraded front pipe and mid X-pipe are designed to optimize exhaust gas velocity, reduce turbulence, and equalize pulses from the S58’s twin turbos. The result?

  • Faster turbo response
  • Sharper throttle feel
  • A deeper, smoother, and more refined exhaust note

With the valves closed, the system maintains a civilized OEM-like sound profile. Open the valves, and your G80/G82 transforms into an aggressive, motorsport-inspired machine with enhanced clarity, volume, and character—exactly what the S58 engine deserves.

Constructed from high-quality stainless steel with precision TIG welding, the Fi Valvetronic muffler ensures long-term durability under extreme heat cycles. A set of quad silver tips finishes the system with a clean, premium M-Performance look.

Perfect for enthusiasts who want OEM functionality with a major improvement in tone, excitement, and performance.
