Ok this is really starting to kind of bug me, I have BBK LT's, BBK o/r H pipe, and Maggie catback. The car sounds fine crusing and awsome at WOT but when I decel it sounds like I have on glasspacks with the pop pop pop. Is this something I just will have to live with or is it my combo that makes it sound this way? I had a catted X pipe on it until one or both of the cats started plugging up on me but it did the same thing with that on there, just not as loud. :shrug:
