yea, my MPx and the President of CSC Rons B&B Exhaust are pretty go**amn loud. I run a cat-delete dpwnpipe (no cats), and 3rd gear at about 2200-2500 its really loud and attracts the cops pretty good. The B&B is even louder than the MPx i've heard from Ron. Also, I've heard the DC Sports is pretty quiet for an exhaust. If you want obnoxious fo MPx or B&B if you like.
