Loud "pang" noise from exhaust on startup

Just recently started noticing this noise once the temp dropped below 32F.

On cold startup, about 5-20 seconds in there is a very loud metallic "PANG" or "TINK" noise coming from the exhaust area. Very audible from the interior and my coworker said it was loud as hell from the outside. It only happens once very shortly after startup, doesn't matter if it is in Drive, Park, or Reverse.

Anyone else having this issue or know what might be causing it?
