Active Autowerke Signature Single Mid-Pipe – BMW M3 / M4 (G80/G82)

OVERVIEW

The Signature Single Mid-Pipe brings Active Autowerke's single mid-pipe expertise from the F8X M cars across to the G80 M3 and G82 M4 as the alternative to their X-Pipe mid-pipe — a similar price point and a slightly deeper tone, though not offered with secondary cats. The G8X cars have earned rave reviews for performance, but the sound is a muffled one, leaving the driver to wonder whether they are really driving a BMW M car; Active Autowerke's answer is a full system of a choice of two mid-pipes, a rear axle-back valved exhaust and GESI catted downpipes. It suits most aftermarket exhausts and mufflers and improves on the factory mid-pipe by mixing the exhaust pulses earlier and for longer.
