Active Autowerke BMW N55 F3X M235I 335I 435I F87 M2 Downpipe exhaust upgrade

Active Autowerke BMW N55 Downpipe   BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the F-Chassis models beginning in 2012. The Active Autowerke N55 downpipe for the M235i, 335i, 435i and M2 helps unleash some of the potential that is restricted by the OEM downpipe. Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the N55 is quite restrictive, which results in slower exhaust gases and slower turbo spool. The Active Autowerke F-Chassis N55 Signature down pipe utilizes 3.5 diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. Our downpipe is the perfect addition for any F-Chassis N55 and especially those with an upgraded turbo system!
