Thanks I'll add that stuff to my list,
I had some people suggest cracked transmission mounts and maybe a cracked flywheel, judging from my video and the info I've provided do either of those sound legit,
Also has anyone here ever even heard a sound like that before?

What's your oil pressure look like when it's idling? How about when you're driving? What does the oil pressure gauge indicate when you're in park with the engine idling once the car gets up to operating temp?

did you find any metal shavings or anything in the oil pan? I would check to make sure nothing is loose while your down there. Doesn't hurt to look for a worn bearing.

Can't tell anything from the pictures..
Reach up in there with your fingers and give the rod caps a wiggle.
If any one of them move around easier than the others you have a spun rod bearing.

Pull the plugs and check if one is wet. Get a mechanics stethoscope and try to isolate the sound. I had a similar noise that turned out to be a bad cam that then chewed up the the lifetr rollers.

Seeing as you just got the headers installed have you re-checked the header bolts? sometimes they can back out of the hole a little and cause a leak, Also depending on the brand/type of gasket used you may have a leak at one of the gasket contact points?....
