2021 2.7 Cold Start Noise

[ameis2504]

Hey all,

I have a 2021 2.7 that is making this pretty loud cold start metallic rattle sound. It only happens on the first start of the day, and doesn't happen for the rest of the day but lasts for 2-3 minutes until idle rpms drop below 1k. Noise is in the attached video and it doesn't start until the 14ish second mark after ignition. I got underneath the truck and applied some light pressure to the wastegates but that didn't seem to stop it. I haven't really taken a look at all the heat shields yet mostly because I don't know where all of them are but the sound is loudest laying right underneath the transmission. Bringing it into the dealership tomorrow, my neighbors heard it the other day and its significantly loud. Anyone have similar sounds?

Bringing it into the dealership tomorrow just dont really want them to tell me this is normal, my neighbors heard it the other day and its significantly loud. Anyone have similar sounds?
