The Active Autowerke Signature down pipe is designed with the intent to makes the most in power. The down pipes are created with the least amount of restrictions possible by utlizing a full 3.00" piping throughout with the least amount of bends and mostly straights where 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 impleller now has the ability to spool that much faster. The end result is more power.

For added duability, factory like suport braces are also implemented to alleviate stresses upon the turbos.
A 02 sensor simulator is also included with the Active Auitowerke down pipes to satisfy the annoying check engine light or fault code that will appear whenever the exhaust catalyst is removed.

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.
