Are you hearing really deep sounds at low rpm?
At this point I'm wondering if it was not installed properly at the dealer. Thanks.

Yes, mine sounds the same. It seems to resonate more at the lower RPMs in the cabin. Otherwise, it's pretty quiet inside the cabin. Again, my perspective and reference is my 335is stock exhaust which was louder throughout and had an ever slight drone with the left flap open.
