Car is currently at the dealer. They acknowledge the 20-30 second cold start rattle is not normal noise and are committed to fixing it. They are going to replace the muffler tomorrow, even though I pointed out it's clearly the tips because the noise goes away when you remove them. Seems like a hoop they have to go through for BMW, but they said if the new muffler doesn't fix it, they'll look at changing to the new style tips with the clamp.
