Bad cat?

Okay so I been crawling underneath my truck and having my step dad give it a little gas to get it to rattle. Up front engine sounds quiet as ever but the rear of it is noisy. So I crawl under by the cats. I don't really hear anything hitting the sides. But does sound like its echoing through them.

Any small white granular pieces making their way out of the exhaust? Rap on the gas kinda hard and see what happens.

Don't know if you have a bad cat...but the first video your truck sounds like mine...with the rattle that sounds like a lifter around #5 cylinder...probably around 900rpm...
