Active Autowerke BMW M2 G87 Equal Length Midpipe

BMW actually attempted an equal-length exhaust solution on the G87 from the factory, using a crossover pipe from the short downpipe. But they overcorrected, making the driver's side exhaust longer than the passenger side, leaving the factory system still imbalanced. Active Autowerke's patented Signature Equal Length Midpipe corrects the passenger side exhaust length specifically, giving the G87 a true equal-length system and a genuinely smoother sound.

This brings the same expertise developed for the F8X and G80/G82 M cars to the M2 G87, with Gen 2 advanced resonators specifically engineered to reduce rasp and unwanted frequencies, including the "2k RPM buzz" and cold start rattle some owners report. The equal-length technology itself is protected by US Patent 11248511 and EU/UK Patent 3882441, genuinely unique engineering rather than a generic aftermarket solution. Constructed from 100% 304 brushed stainless steel with factory-style flanges and clamps, the system installs with only two cuts needed in the stock midpipe, remaining a bolt-on that most can perform, with the stock midpipe reinstallable if ever needed. It includes the Active Autowerke G87 chassis brace as standard.
