I would check the engine mounts for excessive movement. The engine exhaust can contact the underside of the car and make a rattle sound. Can you please shoot a quick video with your phone so I can hear the noise? that way I can tell for sure what's going on. You can upload it here with your response. We need to hear the noise so we know which direction to go to help you fix the car. It takes time to upload so please be patient.
