2018 Camaro AFM exhaust valve rattle????

So I recently got an Mbrp axel back exhaust muffler and tips put on about a month ago. And a few days ago it started making this rattle sound. Heat shields and bolts and everything were checked but that was the problem. However those AFM valve springs move and are very loose when I touch them. Are they suppose to be loose? Could that be the issue??????

Sounds like them to me, I had that noise and it went away when I cut my valves out
