Exhaust Rattle ... Muffler or Cat?
I get a rattle at low rpm's. I looked around and hit the cat a couple times and it doesn't sound like anything was loose inside. It actually sounds like its the muffler. I've never heard of a muffler getting clogged like a cat does but here's the link to the video, see what you think (the visuals suck, audio is all that matters):

My cat's rattling like crazy and it's definitely a different pitch than that. Mine's much higher. Sounds like gravel in the pipe. Yours sounds almost like a loose slip joint on the pipes, or a muffler tapping the frame.

I'm not too worried if it's the muffler, I was planning on getting a cat back soon, but I do have to pass an emissions test coming up so I'm just trying to make sure that it's not the cat that's going bad.
