Strange noise when accelerating

Just as the post title says, high pitched grinding/scraping when accelerating. Any thoughts?

Hit around on your exhaust...

 

It sounds rotational
As the camera points to rear glass, assuming sound comes from rear

check drive shaft and u joints and carrier bearing

 

Sounds like a metal on metal rattle to me, I second checking the exhaust and near it.

 

Hit around all over the exhaust with a mallet. Still making the noise. It sounds like it’s coming from right underneath the cab. I pointed the camera through that window because that’s where you can hear it the best. Really don’t want to take it in and mechanics to give me the run around. Just hoping it’s nothing major.
Forgot to mention: 260k miles. No idea when the clutch has been replaced.

 

+1 for exhaust. check the hanger brackets.

 

I had the same noise in a silverado i had in 2007. It was coming from the catalytic converter. Broken pieces of honeycomb rattling.
