Single Mid Pipe (Retains OEM Muffler) for BMW M3 G80 G81 / M4 G82 G83 Coupe Sedan Wagon Convertible S58 20+ (Copy)

The Fi EXHAUST BMW G80,G81,G83 M3/M4 single mid-pipe is tuned for drivers who prefer a deeper, throatier exhaust note. Built from premium T304 stainless steel, the single mid-pipe layout emphasizes low-end resonance and delivers a muscular growl that stands apart from both stock and other aftermarket exhausts.

As highlighted in our Fi EXHAUST article on the single mid-pipe sound , the cold start delivers a noticeably deeper growl, especially below 4,000 RPM. While the S58 engine naturally carries a hint of rasp, the single mid-pipe keeps it far more controlled compared to the dual mid-pipe setup and most aftermarket alternatives. For drivers who want an aggressive tone without excessive rasp, this is the perfect choice.

With valves closed, the system offers a subtle, comfortable drive. Open the valves, and the single mid-pipe brings out the raw, resonant character of the S58.

Switching between street and race modes is seamless, whether through factory exhaust/sport buttons, drive modes, or the Fi Pro remote control upgrade.
