I have driven a step 335i with Borla exhaust for a day. By the end of every drive I wanted to shoot myself. The droning was pretty bad. Considering that my car has Eisenmann Race and I don't hear any drone, imagine what Borla sounded like.

Just my input. I don't exclude that it might not have been installed properly.
