I Was thinking of taking off my catback off will this have any changes in performance becasue i heard that it is a good way in cleaning ur pipes or engine to get rid off all the gunk and crap ur engine builds up.
a Cat CLEANS the air out of the exhaust ports coming from your motor, getting rids of, carbon monixed, knocks, and other harmful toxics
so removing them you will see some performance but in no way will it clean anything at all getting rid of them
if you'd like i can show you a pic of my exhaust with out a cat...
its got 3-4k miles and its blacker then the night sky
