I've got a 90 gt bone stock looking into what mid pipe to get don't want it to loud had plenty of stangs before but never had one with an x pipe. Plan on going with the dynomax ultra flow ss cat back. Which should I choose h pipe or x pipe?
Eliminating the cats will definitely make the car louder. As for an X or an H pipe, that will depend on what sound you are looking for. The H pipe tends to have a deeper smoother tone, where the X pipe will have a raspier more exotic tone if that makes any sense. I would recommend hopping on youtube and listen to some sound clips to determine which suits your taste best.
