Only hear at idle, once rev'd goes away.
Still has lots of power and runs great.

 

Kinda hard to tell where it's coming from in the video.
I'd check the following:
Smack the catalytic converter and see what you get, they're known to rattle like that.
Pull the inspection cover on the bellhousing and see that the flexplate bolts are tight. Visual not enough, put a wrench on them.
If they are good, remove the serpentine belt and fire it up. If the noise disappears it's a belt-driven accessory of some sort. Water pump perhaps?
Any other details you an offer? Any different when warm? Cold? Approximate area the noise is coming from?

 

It's not very noticeable when its cold, after it been driven and warms up is when I can hear it.
I will check the flexplate bolts this upcoming weekend.
It definitely sounds like its coming from there.
