might be the heat shields, the exhaust rubbing/hitting up against something, that honey comb ish rattling around in the cat. could be several things, i suggest put it up in the air on a rack or just some jack stands and crank it up and go from there.

i had a car once where the lil press flange that goes onto the flex pipe was lose and made a rattle noise, i took a hammer to it and it stopped.

check the heat sheild that goes around the cat, sometimes they loosen up over the years and start touching other metal parts and making noises!
