BMW S58 Titanium Racing Cat Back Single Exit (G80/G81 M3 & G82/G83 M4)

The SLN Performance Titanium Racing Cat Back is the ultimate weight-saving exhaust upgrade for the S58 BMW G80/G81 M3 and G82/G83 M4. A full titanium cat-back built around a true single mid section and a single exit, it strips significant weight out of the rear of the car versus the heavy OEM system – exactly what owners chasing the fastest times are looking for.

This race-focused system has already helped set some of the quickest times seen on stock-turbo S58 cars, pairing serious weight reduction with an aggressive, motorsport-derived titanium soundtrack. Every section is 100% TIG welded with OEM-spec flanges and mounting for a precise fit.
