[QUOTE="Gilaguy23, post: 435989, member: 19498"] I couldent open the pic but you might wanna knock on the cat a few times when its cold and not running obviously. Jeeps seem to eat cats and when they do they often disintegrate internally and rattle. Not knowing an 89 there might be a flapper valve in the exhaust manifold that is closed when cold and opens when hot off a thermostatic spring. They wear and can rattle as well. Just a couple common rattles that come to mind. [/QUOTE]
