Maximize Power

A turbo impeller wheel speed is mostly limited by the exhaust backpressure 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 HP. The Active Autowerke Signature down pipe is designed with the intent to maximize in power.

Faster, More Responsive Engine

The down pipes are created with the least amount of restrictions possible by utilizing a full 3″ piping throughout with the least amount of bends possible, that is impressive when compared to the factory diameter of 2.50″. 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 stresses upon the turbos. Made from 304 stainless throughout ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match. All flanges are 304 stainless with the 0.060″ wall thickness (~1.5 m.m.)
