exhaust smell
 

On my 82 c10 my exhaust smells. I am having a hard time explaining it cause its not a rich or lean smell. Never owned a car with a catalytic converter before but I know they can clog so I was wondering if mine needs replaced?

A bad cat generally smells like rotten eggs. I'd be under the truck and going through the entire exhaust system with a fine-tooth comb, looking for any and all leaks. Have you noticed any loss of power, especially under hard acceleration?

when the cat goes bad alot of times either the cat or the pipe directly before it will heat up red hot.. A bad alternator that is overcharging can also smell like rotten eggs

also if you either ran over a critter and knocked parts of it onto the cat or a critter crawled onto your exhaust and died , that can smell wonderful also, as will plastic that landed on the cat

Well I crawled under and do not see any leaks or signs off exhaust issues. Y pipe looks darkish though. Since I just bought it a week ago its hard to say a loss of power or not.
