salaam:

water is a by-product of the combustion of hydrocarbon/gasoline. gasoline does contain hydrogen, and when gasoline is burnt, some of that hydrogen combines with the oxygen being used to burn it, producing water.

most of the time, the exhaust is hot enough & the water remains in the form of invisible water vapour. when engine is cold, the exhaust pipe is cold, or the outside air is cold, this water may condense and become visible as steam or as liquid water dripping from the tail-pipe.

in combustion of methane we get:

CH4 + 2O2 ? CO2 + 2H2O + energy

in combustion of hydrogen we have:

2H2 + O2 ? 2H2O + heat

similarly during all combustion processes the resultant includes formation of water vapour.
water from the tail-pipe also indicates that your air/fuel ratio is ok_ & the engine is tuned correctly.
but in adverse cases it may refer to a leaky head-gasket too!
