Active Autowerke S63/N63 Catted Downpipes GESI G-Sport | BMW E70 X5M / X6M / X5 / X6 2010-2013

Active Autowerke is proud to bring you our hand made Signature S63/N63 Downpipes for the twin-turbo V8 BMW X5M, X6M, 550i, 650i, X5, X6 models. Please note that G-body vehicles with the N63B engine will need a different version of the downpipe - if you are buying a downpipe that also fits the F body cars, it will not fit your vehicle - Active is always doing R&D to ensure that you get a product with the proper fit.

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 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.
