BMW S63 DOWNPIPES | V8 BMW X5 M AND X6 M BY BMW TUNER, ACTIVE AUTOWERKE

Active Autowerke is proud to bring you our hand made Signature S63 Downpipes for the twin-turbo V8 BMW X5 M and X6 M models. 

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 steel the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match.

NOTE: designed for off-road use only, car will have CEL without Active Autowerke Software Upgrade for Off-Road use only.
