Curious as to why youve got custom piping from the resonator back, and then have a high flow cat? If i were you, i'd go to a muffler shop, have them put in that last piece of custom piping from your high flow cat to your resonator, and then put in a bigger inlet/outlet size resonator(not your stock on).
