Fabspeed Competition Downpipe for BMW M235i F22

Replace the M235i factory catalyst section with a straight-through competition downpipe. This is the catalyst-free option, with a louder exhaust note and possible engine fault lights. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.

Use restrictions
