rattle noise at low idle.. 06 TJ 4.0

Went out today and cranked her up. It rattled and I noticed it continued to rattle a low idle.. it has no rhythm it. Sounds like random chatter or rattle.. rev it up or fether the gas and you don't hear it.. It's a automatic trans but I am going to pull the inspection plate and check the converter to flywheel.
My question is.. I noticed there are 2 converters right off the manifold.. do these come loose very often. Hard to pin point exactly where the noise is coming from...

It sounds like an exhaust clamp came loose, you're probably right. Just don't touch the pipes without a seriously insulated leather glove, but I'd let it idle and grab the thing and see if it stops. You could look for a broken clamp when it's cold in the morning, but it could be rattling without one being broken.

Found no brackets loose. My wife took it to tan and back. Now I don't hear any noises. Idle or reving it up. Only doing it when cold.
