Strange rattle from rear on 2003 Boxster S

Take a rawhide or rubber mallet and give all 4 catalytic converters a whack...not too hard mind you, just enough just to see if the the honey comb internals have come loose...

Thanks for the heads-up Porsche Chick..I am certain there is not a rattlesnake in the trunk, but it sure would make it easier to fix the problem if there was...LOL! Since I recently replaced the brakes and rotors, is it possible that that noise is coming from my hand brake being out of adjustment? It takes about seven or eight clicks to engage firmly. Is that too much play? It really sounds like loose brake components the more I listen to it. I have whacked the cats and mufflers, poked and bent all the heat shields that I can find that are remotely loose and pounded the suspension components with a rubber mallet over and over to no avail. Kinda sounds like loose calipers on an old pickup from the eighties or nineties if that helps any. I think I am going to look into the hand brake....Anyone else ever had hand brake issues??

Hand brake is easy to adjust. Remove the cover off the bottom of the centre console storage, just need a couple of spanners.
