I did a cleanout for a guy a few months ago. Part of the junk he had me hauling off were these things. He drove a Dodge Diesel 1 ton truck and said he had to replace the exhaust system on it. It is a post 2007 model truck and he said one of these are the catalytic converter. First question, can someone identify which one of these three pieces is the catalytic converter? Second, I have read several post on this board and I was wondering if there is any value to these beyond the shreddable scrap iron value? I have never tried to sell a catalytic converter but understand some are worth alot of money.
