Well did some more trouble shooting I think I have narrowed it down.

I got both mufflers off shook them both vigorously no noise other than some water. I think I might have found the problem though.

I bought my car 3k miles used and I think the previous owner had an aftermarket exhaust. Well somehow it was up in there with no rear exhaust hangers. Maybe the dealer did it when they tried to resell the car, who knows. Long story short when I had the exhaust put on at Midas they found that and gave me two hangers and bolted it up.

Well here is what the hangers look like. Something seems off. 1 of them looks cut and the other looks normal. Both Ford parts. Also the nuts I took off look the same but for 2. Also I only pulled off 6 which I am not sure is the correct amount or not. I think the hangers were what was buzzing around making the noise. I am about to go for a final drive with both mufflers off to see if the noise is still there bu I'm nearly 100% sure it will be gone with the mufflers and hangers off.
