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 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!
- Designed to be as unrestrictive as possible
- 3.50" diameter piping allows for maximum power output
- Quicker turbo spool
- Easily bolts-on – no cutting or welding required
- Durable construction from 304 stainless steel
- Precise fitment
- Modular design for later upgrades
ACTIVE AUTOWERKE N55 SIGNATURE DOWNPIPE BENEFITS
The speed of a turbo’s impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke’s Signature downpipe, your N55 can rev quicker, and deliver more horsepower and torque.
Minimizing back pressure while remaining daily drive-ability was the goal of our N55 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install. Note: Because this down pipe modifies the factory emissions system it is designed for off-road or racing use only.
After months of research and development, our engineers settled on a 3.5” diameter pipe which utilizes the least number of bends possible. However, the Signature N55 down pipe still fits easily into the OEM location, with a painless installation process.
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!
