In the most extreme cases, an exhaust pipe can be so damaged or corroded that it will come loose, and drag on the road as you drive.

What about if you hear a rattling sound under your vehicle?  This usually means that there is something which has come loose. Generally, it is a bracket, piece of the exhaust pipe, or a heat shield.
