Thanks for the explanation. When I brought the car to the dealership, they did find a broken bolt underneath the car contributing to some of the rattling. There still is some slight rattle going on. Now I know the previous owner was greentrbo95gst, and he previously had DPs installed..Well at least the car was broken in properly.
