Rattling Focus exhaust

I have a 99 Ford Focus.

There is a very loud rattle coming from the exhaust area when hot. The exhaust isnt loose and has no holes in it. I have been told it might be the cat, have you any ideas?

The ceramic matrix of the cat converter could have broken off its mountings and be rattling around inside its metal pod.
