Do I have a bad Cat or muffler?

How do I know if it's my cat or muffler thats going bad, and how can I test them? What are some symptoms? or I'm thinking that maybe it could be a bad intake problem but that should be easy enough to test for. The zj idles fine and drives tell you get it to a certain point then dies.
