Active Autowerke S63 Downpipes for BMW X5 M & X6 M (P/N 11-034)


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 much faster and more 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. Construction of the down pipes from 304 stainless steel ensures a robust and durable exhaust that will provide trouble free performance with longevity to match.
