I'm building a list of parts I want for the mustang I'm buying later this year and I've been shopping around for exhaust combos. I've come up with BBK 1 7/8 Long Tube Headers with the BBK catted x-pipe(long Tube version) and the Solo Performance cat back but I was wonder if anyone has ever done that and if it works well and sounds good because the cat back comes with the stock h-pipe style mid pipe but since I'm getting long tubes and a long tube style mid pipe if I just didn't use the h-pipe that comes with the cat back would the length be off even though BBK and Solo Performance say they mount up to stock location (where the x-pipe would end is stock location and same with the start of the cat back)?
