Looking to increase the power on your BMW 135i and 335i with the N55 single turbo engine.
Install the Active Autowerke 135i N55 Downpipe and unleash the true power that is hidden in your BMW 135i and 335i.

The turbo is often described as a device that creates free horsepower becuase it is driven by already spent exhaust gases. In the BMW 135i and 335i, this exhaust gas is being restricted by the current factory downpipe which slows down the speed of the factory turbo to maintain or reaching the turbo optimum peak.  
The 135i 335i N55 downpipe was created from inception as a test pipe that would substitute the factory exhaust catalyst to relieve this back pressure.  As such, the end result is a product primarily suited for off road applications like racing.     
A turbo impleller wheel speed is mostly limited by the exhaust back pressure within the system.  If one could eliminate some or most of this exhaust back pressure, the turbo will spool that much faster and effortlessly resulting in quicker engine revs and increase horesepower.

Active Autowerke Signature 135i 335i N55 Downpipe Benefits 
The Active Autowerke Signature exhaust downpipe is designed with the intent to maximize the power. The downpipe is created with the least amount of restriction possible by utilizing 4.00" piping with the least amount of bends possible.  What you will experience is a faster, more responsive engine because the turbo impeller now has the ability to spool that much faster.  The end result is more power.  For added durability, factory like support braces are also implemented to alleviate the stresses upon the turbo.  Made from 304 stainless steel throughout ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match.  All flanges are 304 stainless steel with 0.060" wall thickness (1.50mm)      

NOTE:  Designed for off-road use, the BMW will have a CEL light without the Active Autowerke BMW sofware for off-road use.
