Talking Active Autowerke N55 Catted Downpipe , No CEL Guarantee!



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.

This variant includes a 49-state legal EPA approved 4.5" high flow GESI catalytic converter that will NOT produce a CEL! EPA N/GBL/4389/1119

FEATURES:
  • NO CEL when using this downpipe
  • Designed to be as unrestrictive as possible
  • GESI EPA approved
  • High flow 4.50" GESI cat with 3.50" piping allows for maximum power output
  • Quicker turbo spool
  • Rated for 500 to 850 hp applications
  • Withstands up to 1500° F
  • Can reach operational efficiency within 9 seconds of startup
  • Easily bolts-on – no cutting or welding required
  • Durable construction from TIG welded 304 stainless steel
  • Precise fitment
  • Modular design for later upgrades
  • Made in Miami, Florida
  • 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.

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!

No tune is required, if course with the right tune you get even more gains since you can run stage 2 maps

Nice Work. Appeals to those of us that want to upgrade performance without emissions issues. I went catless once, would never do it again!

Will this downpipe lower underhood temps a little - higher flow, less heat bound up in the dp so close to the motor -

Thanks!

Anyone have issues with warranty from BMW with this install ?

Not sure if/when I'll tune, but interested in a bit more power...this seems simplest. Guessing need to do charge pipe at same time.

Hi,
The warranty is only effected if the mod is to be blamed for damaging a stock component.

In the case of downpipes, on its own it does not add any pressure on other components. On the contrary with higher flow cats, it reduces backpressure on the turbo
