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. Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you’ll be pleased with how robust and durable this down pipe is Trouble-free installation and a long lifespan ensure that you’ll enjoy many miles of performance with your N55.

Our F-Chassis N55 downpipe is one of a kind! We've fabricated a 3.5" V-Band flange in the middle of it to create a truly modular design for any enthusiasts that would like to upgrade to a complete 3.5" exhaust later down the road. The OEM downpipe shrinks down to under 3" where it meets the stock exhaust. We've inserted our 3.5" flange so that if you have an M2 you can later upgrade to our complete 3.5" turbo back system, or if you have a M235i, 335i or 435i you'll have the option to create your own 3.5" turbo back system! Our downpipe is the perfect addition for any F-Chassis N55 and especially those with an upgraded turbo system!


Fits all F-chassis n55 cars from 09/2013 up only!
This downpipe system is designed for off road and racing applications only!
Bmw n55 with this downpipe will throw a cel without an active autowerke software upgrade for off-road use only!
