Ok so today while driving to school, i suddenly hear a wierd rattling sound coming from the exhaust. I think it may be the Catalytic converter because it sounds like its banging in the inside. what do you guys think and also i had parked my car today and just revved the car to figure what the noise was, and the car just shut off on me and it had shook after i let go of the gas. Engine mounts?

Could be your cat. The noise might be unrelated as the cat has a heat shield that tends to vibrate and make noise.

Sounds like the cat to me not the shield. Remove and inspect.

I your cat insides are loose, they give a bad reading to the O2 sensor and that might incorrectly adjust your a/f ratio.
There was a thread about a guy with a similar problem to yours. He took off the cat and put on straight pipe with a defouler and all his problems were gone.

Bad engine/trans mounts will not make your car stall out.
