I asked the same **** but got no responce, Anyways I was also wondering whats the difference between a cat and a resonator? I was thinking about picking up the piping from http://www.accordinglydone.com...th=34 Then from that same website getting an extra foot of pipe and have that welded in place of where the stock muffler would be then have a canister muffler welded on the bent piping that would come out the driver side... I just dont know what kinda muffler to get... Or cat or resonator...
