Yup, I agree here. It needs replacing. I wish I didn't let mine go as long
as I did in my 94- I drove way too long with that 'rattle', and it ended up
taking my muffler out in the process. No cheap way to do it, either.

Even though it just sounds like a metal heat shield or something rattling? It
doesn't sound like the internal honeycomb stuff.

I'm out of the 80K warranty...

Did you go poking around there? I don't know if it is true of your cat or
not, but I've seen sheet metal heat shields tacked onto the bottoms to
reduce the chance of starting grass fires. After a while they rust,
loosen up and make a tinny rattle. If that's what you've got and it is
loose enough to rattle, it is probably loose enough to pull off with your
bare hands.
