Active Autowerke is proud to bring you ouru00a0hand madeu00a0Signature N63 Downpipes for the twin-turbo V8 BMW .

A turbo impeller 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 increased HP. The Active Autowerke Signature down pipes are designed with the intent to maximize power. These 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. 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.

Made from 304 stainless steelu00a0the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match.
