I gutted the cat on my Camaro. It really has no noticeable effects for performance, but it's easy to do. I cut it off, stabbed the insides with a long screwdriver, and welded it back on.
If your cat is bad, get under there and hit it with a hammer. If its bad, it'll rattle.
If your truck runs clean enough, it should pass the sniffer. (All of my trucks pass without cats). It'll also pass the visual test if you put the gutted cat back on.. Good luck with your project.
