I have a 2000 mustang GT with a pypes offroad h-pipe. I want to get longtubes but pype's does not sell longtubes on AM or LMR. I did some research to see if my midpipe will fit longubes such as bbk or mac since my midpipe bolts on to the stock manifold; however, they say that you need a shorty bbk midpie to fit the bbk longtubes and the same situation for mac. I really do not want to get rid of my midpipe since i bought it for a good deal. Anyone know a way I can install longtubes with a guaranteed fitment?
