Valvetronic Single Mid Pipe Exhaust System for BMW M3 G80 G81 / M4 G82 G83 Coupe Sedan Wagon Convertible S58 20+

The Fi EXHAUST BMW G80 M3 single mid-pipe valvetronic exhaust system 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.

The exhaust is finished with classic quad tips, preserving the iconic BMW M look. When paired with intake upgrades and ECU tuning, dyno testing has shown gains of up to +114 WHP and +72 lb-ft, making this system as performance-driven as it is distinctive in tone.

Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.
