BMW Catless Downpipe - Active Autowerke 11-028
BMW Catless Downpipe - Active Autowerke 11-028
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!
FEATURES:
- 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!
NOTE:
- 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.
Brothers Mike and Karl Hugh were bred to play with power, it seems. As young men growing up on an island, doing things correctly for oneself became their ingrained credo. Their adolescent projects – bicycles and dirt bikes – were always the best performing. And that soon set the tone for the BMW tuning hobby they graduated to. By 1981, Mike and Karl were ready to get serious about their longstanding passion for a higher standard of BMW performance. Active Autowerke was born. Their motto at the time: "Anything and Everything BMW". They probably should have included “everyone” in there, too – since the endeavor was a classic family affair – with many branches of the Hugh family tree pooling their talents. The timing was ideal, and the company quickly grew as America’s motoring public developed a healthy appetite for the Bavarian treat. Soon Active Autowerke had grown into the largest independent BMW service center in Florida – with the most sophisticated equipment arsenal in the industry, certifications from leading componentry firms such as the Robert Bosch Corporation, and repute for setting the benchmark for service, integrity and professionalism.
