HEY PEOPLES do i need to get another resonator if i put a new exhaust system into it?

was quoted $180 resi-back (waste of time) or $320 Cat back with new resonator (maybe $50 more for mandrel bending) i was thinking is that worth it? should i buy my own resonator help me out ^_^

or would the exhaust place have a better resonator that those ones?? exhausttechnology in adelaide.

dont know how it increased that much because there is only like 8 inches between the resi and the cat...weirdness im sure a resinator doesnt cost $200

ohh wells give me some help fellaz
