In extreme cases, it can blow the muffler wide open.

A muffler going bad can be caused by many things. But generally, it is either contact with the ground causing a dent, oil burning causing sludge and residue in the muffler, or corrosion from age and moisture in the exhaust pipe causing a hole or the collapse of baffles.

A faulty muffler will not cause this but a clogged catalytic converter will.

A hole in the muffler would cause a knocking sound in your muffler. A loose exhaust pipe can also cause a knocking noise.

You drive a car without a muffler, it is not vital to the car's system. HOWEVER without the muffler the car is vastly louder, in some states causing you to receive a ticket
