Another noise diagnosing help

[fatmonk8]

Hey all,

I got another noise I'm trying to figure out.

Kinda sounds like a very light metal scraping noise when I put a little gas on the throttle. It's pretty noticable when I'm driving around and mistook it for brakes or a heat shield, but after hearing it when the truck was idling, I verified it makes the noise in neutral and when you set on the gas.

Nevermind, figured it out. Passenger side catalytic converter.

Guess I need to figure out why my cat failed.

Might be due to my slight coolant loss maybe

Can't catch a break with this car.
