Again, this leads me to believe there is a prominent metal on metal contact that's causing the rattling. Hopefully this can be fixed with a re-install
Did you check if the heat shield is contacting the rear passenger side muffler? 10 bucks says that is the culprit, I just solved that same issue with my FI exhaust.
