Unleash the full character of the S58 engine with the Xforce Varex Cat-Back Exhaust System, engineered specifically for the BMW G80 M3 and G82 M4. Built from premium 304 stainless steel and finished with quad 4” outlets, this system delivers a motorsport-inspired soundtrack with refined, user-adjustable control thanks to Xforce’s dual Varex valve technology.
The dual 3” mandrel-bent layout maximises exhaust flow while maintaining excellent ground clearance. Exhaust gases travel from the OEM 2.75” inlets into dual 3” pipework, then through a single east–west Varex muffler equipped with two independent Varex valves, giving you precise control over tone and volume. Open the valves for a raw, aggressive note, or close them for a more subtle, premium sound suited to daily driving.
Designed for enthusiasts who want the best balance of performance, sound, and quality, this system transforms the G80/G82 driving experience while retaining OEM-like usability. Installation is straightforward thanks to the V-band clamp system and direct bolt-on fitment.
