I want to replace my stock exhaust from the cats back and have been looking at both the Billy Boat (B&B) and the Remus exhaust systems. I've had lots of feedback on the B&B stating it's a good exhaust, quite loud, and possibly a little too loud. I've been told that the Remus, which is equal in performance gains, is closer to stock but still offers a nice growl when getting on it and a deeper tone without droning. Does anyone have first hand experience with the Remus? It seems a little more appealing to me. Finally, does anyone know where I might be able to get a BMWCCA Member discount on the exhaust? I was planning on buying it from BavAuto.. Thanks in advance.
