I was wondering (I'm sure this has already been discussed) but how do you clean out a catalytic converter? I figure it needs it and thus will improve engine performance.
Thanks

 

U can't clean a cat it shouldn't be bad unless ur running rich which would clogg it or melt it one way to check if it's good is take a temp gun and check temp b4 the cat and after shouldn't have more the 50 degree diff

 

you could gut it, then you know its not clogged for sure

 

Ok thanks guys
