Can a Car Start If Water Enters the Exhaust Pipe?

[MarcusRose]

The car exhaust pipe is a device installed between the engine exhaust manifold and the muffler to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust silencing system. It allows the entire exhaust system to have flexible connections. Whether a car can start if water enters the exhaust pipe depends on the amount of water that has entered. The situation can be divided into the following two scenarios: If the amount of water is small, the car can start: Typically, the wading depth for cars is in the range of 50-70 centimeters, and the position of the exhaust manifold is similar in height to the intake manifold. If the amount of water is large, the car cannot start: The end of the exhaust pipe has a muffler. If a large amount of water enters (such as from reverse flow during wading or flooding when parked in low-lying areas), it can accumulate in some dead corners of the muffler, eventually leading to rust and perforation.
