Active Autowerke BMW M3/M4 (G80/G81/G82/G83) Single Midpipe

The G8X M3 and M4 have received rave reviews for their performance, but the sound has always been the letdown, muffled enough to leave drivers wondering if they're really behind the wheel of a genuine M car. Active Autowerke's Signature Single Midpipe brings the same expertise developed for the F8X M cars to the G8X platform, mixing exhaust sounds earlier and for a longer period to create a genuinely deeper tone from the stock midpipe location.

It's offered as one of three midpipe choices for this platform, alongside the X-Pipe and Equal Length versions, positioned as the entry point into Active Autowerke's exhaust system, delivering a slightly deeper tone at a similar or lower price point, though without the secondary cats option available on the X-Pipe design. Constructed from 100% 304 brushed stainless steel with an industry-standard warranty against rust, installation requires only a single cut in the stock midpipe using factory-style flanges and clamps, remaining a genuine bolt-on with the stock section reinstallable if needed. It's part of a complete exhaust system for the G8X, alongside a rear axle-back valved exhaust and a set of GESI catted downpipes, and includes the Active G-Brace as standard.
