Product Description
Active Autowerke S58 AFlow Catted Downpipes | BMW G80 M3 21+ | G82 M4 21+ | G87 M2 23+
Description:
The Active Autowerke AFlow catted downpipe for the BMW M3 G80 2021+, M4 G82 2021+ and M2 G87 2023+ delivers a measurable improvement in exhaust flow and turbo response while remaining fully OBD2 compliant with no check engine light.
The Active AFlow high flow catalyst uses advanced substrate technology to maximize flow while keeping emissions within OBD2 thresholds. Paired with 304 stainless steel mandrel-bent piping, this is a bolt-on upgrade that improves throttle response, reduces turbo lag, and adds a more aggressive exhaust note — all without triggering a CEL. Made by Active Autowerke in Miami, Florida.
