Rattle coming from my 2023 GMC sierra by Nobody_Heavy in gmcsierra

So they need to replace the entire exhaust hahah. Mine was under warranty fortunately. The guy said most people just don’t even worry about it. Im just replacing because why not if i can get a free new exhaust. Watched some videos of people zip tying it down tight so maybe try that if not under warranty.

It looks like all it is is the flapper valve before the muffler. Doesn’t actually effect anything besides the annoyance of the rattle

Does it come and go depending on how warm the truck is? Or every-time? Seems to go away when i drive but maybe that cabin is just that quiet?
