Active Autowerke Catted Downpipe - BMW / B46 / G2X / 230i / 430i

Please note that we install the gasket into the downpipe flange as some customers were damaging the gasket on installation. Active Autowerke BMW B46 Catted Downpipe BMW introduced a new valve-tronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continuing into the G-chassis models. The Active Autowerke B46 downpipe for the 230i, 330i and 430 helps unleash some of the potential that is restricted by the OEM downpipe. NOTE: the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with build date of 08/2020 and earlier have the brackets in a V configuration and should order the F-series downpipe while cars with a build date of 09/2020 and later have the brackets in a straight line. If your car was built in the cutover months 08/2020 and 09/2020, please include your VIN in the order so we can ensure you get the correct downpipe. Turbochargers are powered
