I was just wandering. how much do you guys think a barely used DPF and CAT would be worth if I were to try and sale it.

 

Use it as a boat anchor

 

They are pretty expensive new.
If you took it off your truck you better hold on to it. You never know if you'll get caught and have to put it back on.
I already know somebody that happened to and it was a very expensive day for him
