SLE 3.5-Inch Single Midpipe with Brace – BMW G80 M3 / G82 G83 M4 (S58)

SLE 3.5-Inch Single Midpipe with Brace – BMW G80 M3 / G82 G83 M4 (S58)

The SLE 3.5-Inch Single Midpipe with Brace is engineered to dramatically improve exhaust flow, reduce backpressure, and enhance the sound quality of S58-powered BMW G8X models. Designed to replace the restrictive dual midpipe system, the SLE Single Midpipe merges the exhaust gases into a larger, freer-flowing 3.5-inch pipe, resulting in improved throttle response, faster turbo spool, and a deeper, more refined exhaust tone.

Constructed from high-grade T304 stainless steel and featuring a precision-fit underbody brace, the SLE Single Midpipe is a direct bolt-on upgrade that maintains chassis rigidity while delivering noticeable performance and sound improvements.
