Clanking/rattling when revving or starting engine

[WDWFordGuy]

I know this is an old post, I had a similar sound in my '21 powerboost, when it was hot. I bet under it and pressed on a few things. I found one of the bushings for the exhaust mount was half missing so the hanger was vibrating against the mount.

Havnt been able to track down the bushing, it looks like it's part of the transmission mount. I put some rubber electrical tape on it for now. It's much quieter.
