This is normal with a cold exhaust.

If it carries on when the exhaust is hot, or there is white smoke, you've got a coolant leak.

Hello mate,on many modern cars the water you see is a bi product of the catalytic converter.As Paul says if you are only getting the water at cold it's normal.

I don't think its much to do with the 'ideal' mixture - water vapour is a by-product of the combustion process - it condenses in a cold exhuast, but remains vapour in a hot one. On a cold day, you can see the vapour condensing when it reaches the air.

You should not be getting water all the time - only when the exhuast is cold.
