With current damp weather it's a natural reaction. Your silencers can store a litre of water each. Thats a lot of water to expell. However, if the engine is running, is at running temperature, and is seriously steaming as well as dripping water out of the bottom of the exhaust then you have a cracked head.
You would probably have more symptoms if the head were cracked such as overheating, loss of power etc. So it's probably just your silencers are storing a lot of water and condensation due to the damp weather we are currently experiencing.

Oh, that just means that your car is using the bathroom after it starts up. Kinda like you when you first wake up in the morning.
Ok, I'm kidding. But when combustion of gasoline takes place, water vapor is one of the end products along with combustion gases like CO and NOx.
Some of the water vapor escapes the tail pipe unseen, unless it is cold outside. Some of the water vapor condenses and drips out the end of the tail pipe.
As the exhaust gases heat up the exhaust pipes and muffler, less condensation will take place and all the water will escape the tailpipe as vapor.
Hope this little science talk helps.

Molecules that contain Hydrogen, when they are burned (ie: combined with Oxygen in a chemical process we call "combustion",) the Hydrogen and Oxygen combine to form H2O, which is the chemical form of water.
Gasoline contains hydrogen. Oxidation occurs in the engine. The water is normal - the only place for it to go is out your exhaust pipe. Before the pipe warms up, it remains liquid long enough for you to see it drip out the exhaust. Once the car has been running for a bit, the water vaporizes before you can see it.

I had a 1991 Honda Prelude. I had to get a new car after I saw water coming out of my exhaust pipe. Of course, the water came out of everywhere else too once the crane picked my car up out of the lake.

It is normal for it to have condensation from the exhaust..If the car is running ruff,go to the tailpipe and smell the water that is coming out..If it smells like antifreeze then you could possibly have a head or head gasket problem..

Water is the byproduct of the catalytic converter. The converter takes the hydrocarbons from the exhaust and breaks it down into carbon dioxide and water. There's actually a lot more going on but that's the short version. As far as having a blown head/gasket, you would be seing clouds of steam/smoke billowing from your tailpipe if you were so afflicted.

If it's only a bit, it's probably condensation. If it's a lot then ask yr local garage to have a look. BUT if yr car is running ok don't worry all cars do it.

It part of complete combustion. If the air fuel mixture is correct water is part of the end product.

Hot meeting cold = condensation
