BMW G8X G80 M3 G82 M4 Single Midpipe

Upgrade the exhaust system on your 2021+ BMW G80 M3, G82 M4, or G83 M4 with this Single Midpipe. Designed for the G8X platform, this downpipe-back midpipe improves exhaust sound, reduces restriction, and gives the S58-powered M3 and M4 a more aggressive tone.

Built from T304 stainless steel, this single midpipe features 3.5-inch diameter piping and eliminates the resonator and secondary catalytic converters. The result is a deeper, cleaner exhaust note that enhances the driving experience even when paired with the stock rear muffler.

The kit is designed for hassle-free installation with precise fitment and included hardware. Spacers are included for reusing the OEM brace, while an optional midbrace can be used for improved clearance without spacers.
