    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. I'm replacing the full exhaust system so hopefully this is the problem.

    Okay look at it this way since people have to think for you. What if it was internal on the bottom end and not the cats, but you think it's the cats then someone post a similar problem and it wasn't the cats. It's the point of a forum is to ask questions so you can have a idea of what it could be :poker:
