Toyota Repair: Noise from back end, lxe, loud noise

Question
92 Camry LXE...205,000 miles...getting a loud noise from the rear on occasion when starting the vehicle..only happens when the car has recently been driven..say it has been sitting for 30 minutes or so..does not happen when car has been sitting overnight..noise lasts for about 10 seconds and gradually fades away...happens while in park..so loud you would think a plane is flying over head!

Answer
Check for any muffler damage and make sure the muffler hangers are not deformed or pushed back, this noise may be caused by the muffler or pipes contacting the body, this normally happens if the car was backed into a curb and the muffler made contact and was pushed forward or the pipe was bent.
