how big is ur exhaust piping? if u have to big of exhaust piping for the exhaust will start baffling (when the exhaust isnt being pushed out its jus sitting there at the end of the pipe) u have no back pressure threw the piping,resinator,cat,and muffler. if u have no backpressure then the motor will start carbonizing even faster on the exhaust side of the head. did u cut your exhaust off? u mite have a bad cat like all the stuffing in the cat could have burned away and now ur piping is two big and will start baffling in the cat.
