Active Autowerke Catted Race Downpipe - BMW F22/23 F3X G20 B46
For over 30 years, Active Autowerke has been the one to turn to for high-quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about.
The B46 downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory downpipes – therefore reducing radiant heat and increasing performance.

Casted upper stainless steel V-Band for precise fitment
3 inch diameter piping allows for maximum power output

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. 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
