Valvetronic Designs Valved Axleback - BMW M3 / M4 (G80/G82)

A valved axle-back for the G80 M3 and G82/G83 M4 that gives the S58 a higher-pitched, cleaner note. It works with the factory downpipes or free-flow front pipes and doesn't trigger check-engine lights. For more volume, Valvetronic pairs it with its single 3.5 in equal-length mid-pipe.
