2000 LS Sport with 112K. check engine light went on, showed right side cat's no good. car runs lean and gas mileage is more crappy than usual. instead of spending 450 on the part plus install, i figured i could spend a little more and get a real exhaust. i don't know what my options are. i was told to get an off road h-pipe, but would that allow me to pass inspection (or would it throw the codes all the time)? any suggestions would be appreciated. thanks.
