If its the heat shield that's rattling then its okay, if not and the rattling in inside the converter it needs replaced. This can be checked and usually a muffler shop will do it for free. Hope it doesn't need replaced though because they can be expensive, my 99 chevy would cost $800 for both.

They can fall apart inside, but it's usually just the heat shield. If you tack weld it back on it will just break loose again. The best fix is a couple of hose clamps going all the way around.
