I seriously think my cat is clogged. Im gettin about.....30" to the gallon,lol. No,seriously,Ive talked to a few guys over at FTE and a couple here,they say it sounds clogged,How could I check it myself,or,if not my self,what does it usually cost to have it checked out? And guys,this time,I have the money to have something done. This truck is begging to piss me off.
