Just removed ar design downpipes from my X6M. Had them for under 3 years. Not many miles. Also comes with 02 sensors. Will post pics soon. Pm for price. These AR Design downpipes will be giving your X5M / X6M an exotic and aggressive exhaust note as well as a Huge boost in horsepower. These S63 downpipes also virtually eliminate turbo lag, and will make your car's engine even more responsive. Be the first to unleash that S63 engine in your X5M / X6M with a set of AR Design Downpipes.
AR Design does NOT grind/polish our welds as some other manufacturers do. Grinding welds compromises the strength of the weld, and can lead to weld failure! Especially critical in applications exposed to temperatures in excess of 1200°F. Such temperatures will also rapidly deteriorate the polished finish.
