How does water get into a car's exhaust system?

Water can enter a car's exhaust system through several means, primarily condensation. When the engine runs, it produces water vapor as a byproduct of combustion, which can condense into liquid water in the cooler sections of the exhaust system. Additionally, rainwater or snow can enter through damaged or poorly sealed exhaust components. It's also possible for water to enter if the vehicle is submerged or driven through deep water, potentially causing significant engine damage.
