I have been ignoring what seems to be a horrible sounding exhaust leak that i am sure is coming from my cats. Totally ruins the Magnaflow Cat back experience if you ask me. Anyway...i was just wondering what kind of cats you guys have used once your stock ones go bad. 2.8 cats to be more exact. Ive herd cut out and weld on Magnaflow hi-flows...but is there really a difference in performance over the OEM cats? Thanks alot.
