...however, it's temperature quickly falls! Automotive exhaust systems rust away primarily because of condensation of moisture in the exhaust stream.
Others have pointed-out that condensation is a very effective way to transfer thermal energy, which drives moisture from the interior of fuel particles. This is phenomenon is effectively used in very many counter-flow drying apparati.

Only pure steam can be considered saturated at 100 deg c and 1 atm. Engine exhaust will have a saturation temperature that is decided by the molar% of H2O in the exhaust. This is typically around 55 Deg C.
