Please ensure your correct model is selected

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration and will need Active Autowerke p/n 11-065. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G. If your car was built in the cutover months 08/2020 and 09/2020, please call in or email us your VIN so we can ensure you get the correct downpipe.
