loud thumping

I think that as the exhaust EXPANDS from the heat of the high speed driving, the MUFFLER is banging at its FRONT EDGE into the frame of the vehicle.....If the exhaust is NOT correctly installed with matching components, then the clearances MAY be TIGHT, resulting in the OCASSIONAL banging.............Ask me HOW I know!!!!!
