Damage to the muffler shell can also loose some of the interior parts. This will produce a rattle from with as the parts are tossed about by the movement of the vehicle.

Exhaust Abnormally Loud

As the sound waves travel through the muffler, the are diminished. If the waves can escape early in their travel through the muffler, the exhaust sound will be much louder than normal. If the damage to the shell occurs later on, such as toward the outlet, the sound waves may have been dampened significantly. This would create a slight increase in exhaust volume.
