Replace the catalytic converter.

It more than likely is the heat shield on top of the converter. It probably has broken loose.
The Catalytic Converter is an emissions control device on your car and can be disabled (illegally). Your car will still have power if it is broken/disabled but will fail emissions.
Tap it and if you hear parts rattling around it's shot. A catalytic converter is made up of ceramic plates, if it rattles when hit it's broken up inside. Replace.
Normally the heat shield on top of the converter is the source of the rattle. It is possible the the converter medium itself has broken into pieces resulting in a rattle that sounds as if there are rocks in the converter. If the heat shield and the rest of your exhaust seems secure, it is likely the converter needs to be replaced.
Then you need to replace it with a new one. A broken converter will allow carbon monoxide into the passenger compartment, and will kill you. It is illegal to remove it and the engine will not run right with it removed.
