Active Autowerke is proud to bring you their handmade Signature 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 downpipes are designed with the intent to maximize power. These downpipes are created with the least restrictions possible, 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.
