I am custom making my own dual exhaust for my Explorer. I am ordering 2 Flowmaster 40 series mufflers, one for each side. I am going to leave the stock system in and just put in cutouts before the cats. Anyway... I was wondering about H-pipes. Do I need to put one in before the mufflers or something, because at the Flowmaster website it says that H-pipes are recomended in all dual-exhaust applications. What does an H-pipe do???
