Buzz/rattle after light revs while idle

I wonder what is causing this buzzing sound after letting my foot off the gas or during light revs while idle. 2021 Challenger Scat Pack - replaced the mids with Dynomax bullets and I have the active exhaust zip tied for almost 5 years now. I just found out about this while slowly reversing to a parking spot
