didn't know that i figured the humidity was low enought there to prevent that.
here we have our fair share of hummidy and you will get moisture in you exhaust all the time.

The water is a normal by product of combustion.Letting your car sit and idle for ten minutes is what's causing the excess.The exhaust pipes aren't warming up equally from front to back and the steam created by the combustion process is condensing into water when it gets to the cooler part of the system.Then it gets stored by the mufflers and blown out when you start driving.Idling your car like this does no real good.Todays cars are designed to be started and driven immediately.

i realize the phisics behind how it works i just assumed the water was coming out of the air.
