Brand new, never installed. I bought extra one for wife's X5M, but it got totaled, before installation. I have it on my e71 X6M and it sounds incredible: low, deep rumble at idle and angry, machine gun growl, at full throttle. Zero drone on freeway. Has larger, 3.5" T304 Stainless quad tips. They are basically resonated straight pipes, made to look like a muffler. Get full-time M mode sound, better flow, throttle response and never deal with choking-up the S63 engine again. Bolts-on in minutes, after old muffler is removed. Just save the existing hanger mounts. Free ground shipping to contiguous USA only:
