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

[Nigel]

It is normal for a car's exhaust pipe to drip water. Here are the specific reasons for water dripping from a car's exhaust pipe: 1. Chemical reaction of gasoline. When gasoline burns completely, it produces water and carbon dioxide. The water vapor condenses into water droplets as it passes through the metal exhaust pipe, and these droplets form water that flows out of the exhaust pipe. This phenomenon is especially noticeable in winter and is also an indication of complete combustion of gasoline. 2. Condensation water from the air conditioning system. When the air conditioning is turned on while the car is stationary, the air conditioning system is more prone to producing condensation water, which usually appears under the front half of the car's chassis and results in dripping water.
