KYOSTAR Single Midpipe Exhaust for 2021+ BMW G80 M3 G82 G83 M4 2022+ G81 M3 S58 3.0T

KYOSTAR Single Midpipe Exhaust for BMW S58 3.0T

The KYOSTAR Single Midpipe is designed specifically for BMW S58-powered M models, offering a more direct exhaust flow and a deeper, more refined exhaust note without compromising daily drivability. Replacing the restrictive factory center section helps reduce backpressure while improving exhaust efficiency across the entire RPM range.

Manufactured from premium T304 stainless steel using precision mandrel-bent tubing and TIG welding, this direct bolt-on midpipe provides outstanding durability, corrosion resistance, and long-term reliability. Whether paired with the factory rear muffler or an aftermarket cat-back system, it delivers an aggressive sound profile and improved exhaust performance for both street and track applications.
