Briefly used catted AR design downpipe that I had installed on my 2011 535i. Unfortunately my car was totaled out, and I no longer need this. It was used for ~14,000 miles and sounded great! I had it on a completely stock exhaust and it made a noticeable difference in sound and in performance. Absolutely no drone. As seen in the picture, the cat is 100% intact. My main purpose for going catted was to keep this mod off my wifes radar, she never noticed.
I'll include the OEM v-band clamp in as well. The discharge side of the downpipe is a slip fit to the OEM exhaust (tip: install, then come back and torque slip clamp on OEM exhaust once warmed up).
I had this install in conjunction with JB4, so I never got a CEL. But, everything I read/understand is that this should not cause a CEL w/o JB4.
This literally retails for $975 (if you can find it)! To me, AR is the best of the best and is well sought after.
