Back pressure sounds

I have an 03 f350 with the 6.0 diesel nd it has started to make a soud that sounds like when my 88 f250 with the 460 had a cat converter get plugged. I was just wondering if a diesel has a cat conveter or if this problem could be some were else on the truck.

well they do have cats, but they really dont change sound if it gets stopped up, it will just lose power.

The other two trucks that I have had this problem on have sounded kinda like a stopped up vaccume cleaner. Then came the power lose and then they got to he point were they would not go over 15 mph. Will it hurt the truck if I were to just clean the cat ouut like I have on the other two trucks?
