SLE Catless Downpipes – BMW G87 M2 / G80 M3 / G82 G83 M4 (S58)

The SLE Catless Downpipes are engineered to unlock maximum performance from the S58 engine by eliminating the restrictive factory catalytic converters. By increasing exhaust flow and reducing backpressure, these downpipes significantly improve turbocharger efficiency, throttle response, and overall power delivery.

Constructed from high-grade T304 stainless steel with precision TIG-welded joints, the SLE Catless Downpipes are designed for high-performance street and track applications. The direct bolt-on design ensures seamless installation while delivering a noticeably more aggressive exhaust note and sharper turbo spool.
