BMW G80,G82 M3,M4 3.0L Axleback, T304 SS, Brushed 3.5" Tips

The G80/G82/G83 is a phenomenal M car—its soundtrack just needs to catch up. Our single 3.5" equal-length mid-pipe unlocks the character the S58 deserves without requiring changes to the OEM rear section. Add the Valvetronic Designs valved axle-back for even more presence and control. Compatible with OEM downpipes or free-flow front pipes, this system is engineered to deliver a higher-pitch, refined note with zero check-engine lights.
