Features and Benefits Of This Product
Looking for downpipes more impressive than the 2.5” factory exhaust piping? Active Autowerke is pleased to present you a 3” performance downpipe. Utilizing a 3” piping system, with the least restrictive bends possible, will dramatically improve torque and engine response.
Having this 3” performance downpipe system will unleash more power potential over the restrictive factory unit. To reinforce the installation, you will need factory like support braces to relieve pressure on the turbos. This beautifully fabricated downpipe is made from 304 stainless throughout for smoother exhaust flow, increased corrosion resistance and longer lifespan.
Want to get more power out of your BMW 135i and 335i with the N55 single turbo engine? Then, install the Active Autowerke N55 DP to your BMW 135i and 335i and experience maximum turbo performance.
The turbo is a device known for producing free HP because it is powered by already spent exhaust gases. The restrictive factory downpipe of the 135i and 335i BMWs hinders the speed of the factory turbo to maintain or achieving maximum turbo performance. To reach the turbo optimum peak, you will need to replace the restrictive factory downpipe with high flow downpipe system. Eliminate huge exhaust restrictions and unleash the true power of your BMW with the N55DP.
This product started as a test pipe that would replace the very restrictive exhaust element to alleviate back pressure. The product turned out to be a great application suited for off road vehicles.
Back pressure within the exhaust piping system slows down the turbo impleller wheel. Reducing some or most of the exhaust back pressure will allow the turbo to work faster and effortlessly. The result is improved engine response and increase horse power.
What if you utilize a 4” piping system with restrictive curves? If the 3” downpipe provides improved turbo response time and power gains, expect a more impeccable performance when you have the 4” diameter piping.

-Quicker turbo spool
