Is It Normal for Water to Leak from a Sedan's Exhaust Pipe?

It is normal for water to leak from a sedan's exhaust pipe. The water leakage from the exhaust pipe is caused by water vapor in the exhaust gas produced by the engine, which condenses into water and is discharged through the exhaust pipe. If the leakage is severe, it is recommended to visit a local repair station for inspection. The dripping water from the car's exhaust pipe is a result of water and carbon dioxide generated after the complete combustion of gasoline. At high temperatures, water exists as steam, which is colorless and transparent. However, when the temperature drops below 100 degrees, the steam condenses into water. The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, used to control engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe generally consists of a front exhaust pipe and a rear exhaust pipe.
Last time my car's exhaust pipe was also dripping water, so I specifically asked a friend who knows about cars. He told me that this is actually a normal phenomenon. After gasoline burns, it produces water vapor, which turns into water when it meets the cold in the exhaust pipe, especially noticeable in winter. It indicates that the engine is burning fuel very efficiently, which is a good thing. However, you should pay attention to the amount of water. If it's dripping enough to form a small pond, that's not quite right—it might indicate a problem with the cooling system. Also, keep an eye on the color. Normally, it should be transparent and odorless. If it has a rusty color, the exhaust pipe might be corroded.
