Can You Start the Engine If Water Enters the Exhaust Pipe While Parked?

[Hudson]

You cannot start the engine if water enters the exhaust pipe while parked. If the water ingress is not severe, you should check the electronic systems and remove the water from the engine to prevent impurities in the water from clogging the three-way catalytic converter or damaging the oxygen sensor, which could lead to engine water damage. The exhaust pipe is a device designed to reduce vibration and noise while extending the lifespan of the exhaust muffler system. Installed between the engine exhaust manifold and the muffler, the exhaust pipe provides flexible connectivity for the entire exhaust system. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings at both ends. To enhance noise reduction, the corrugated pipe may include an expansion joint or mesh sleeve inside.
