You can reduce some noise from going outside using sound deadening, but you're not going to do the "Jim Carrey Ace Ventura open-and-close the door and go from loud noise to no noise" type of thing. Definitely get some sound deadening, it helps inside and out, but don't expect to break the laws of physics.
Also, the worst rattle usually comes from your license plate or plate frame. Put some dynamat or weather stripping between em, and it usually helps a ton.
