I bought the hooker catack and a catco hi-fow cat. The cat is universal the guy fo summit said. He aslo said I need to cut the flanges off my stock cat and wled them on to the new cat. My quesion is the hooker exhuas is 3in, and the stock y-pipe (or whatver) is 2.5, and both ends of thenew cat is 2.5. HOw do I get that one end to fit to the hoker catbck when that is 3in?
thanks
