It's completely loose (can move a few inches up and down) and rattles on the muffler while driving. Easy fix for a noob, or should I take it in? And uh... how urgently? ๐
It's likely more annoying than it is urgent. It looks like the hole where the bolt should be is rough and oversized, so you probably would just need to get a big enough washer to be able to secure it back to the car. You could also go to a junkyard and see if you can get a replacement heat shield that doesn't have worn out holes (giggity)
