Kinda sounds like the rattle I had a couple weeks ago. Ended up being the bracket that attaches from the engine block to the exhaust manifold. It rusted and cracked around the bolt on the exhaust side and just vibrated against the exhaust. Very annoying at stop lights. Was tough to find as it looked pretty much intact. I just bent it out of the way slightly until I can repair it.

To me it sounds like a catalytic converter heat shield. My '06 did that as there is a clamp on the downstream converters that rusts and looses its grip. When it does the shield loosens and rattles. They are pinched together but still rattle. I don't remember if the V6 has the same set up as the v8 but I would think so. Took mine off a few years ago and no issues since.
