Active Autowerke BMW X3M/X4M (F97/F98) PRE-LCI Single Midpipe

Bringing proven single midpipe engineering from the F8X and G8X M cars to the X3M and X4M, Active Autowerke's Signature Single Midpipe was developed at the repeated request of customers frustrated with just how muffled these SUVs sound from the factory, despite their genuinely impressive performance. By merging the exhaust banks earlier and for longer, the system mixes exhaust pulses to create a richer, deeper tone that finally lets the S58 sound like a proper M car.

It's a direct, bolt-on upgrade requiring only a single cut in the factory midpipe, and remains fully reversible, the stock midpipe can be reinstated if needed. Constructed from 100% 304 brushed stainless steel, the system carries an industry-standard warranty against rust. This midpipe is part of a complete exhaust solution for the X3M/X4M, which also includes a valved rear axle-back exhaust and a set of GESI catted downpipes, together delivering the full transformation this platform's sound genuinely deserves.
