Does water entering the exhaust pipe of a car have any impact on the vehicle?

[DiJason]

Water entering the exhaust pipe does have an impact on the vehicle. It can lead to serious consequences such as water entering the engine. If only the exhaust pipe has water, the accumulated water should be removed as soon as possible to prevent impurities in the water from clogging the three-way catalytic converter or damaging the oxygen sensor. To drain the water, simply increase the throttle to expel the water through the exhaust. Below are the impacts of water entering the exhaust pipe: 1. Causing water to enter the engine: If only the exhaust pipe has water, the accumulated water should be removed promptly to prevent impurities from clogging the three-way catalytic converter or damaging the oxygen sensor. Simply increase the throttle to expel the water through the exhaust. 2. Exhaust blockage: Poor exhaust flow can cause the engine to stall, but this does not necessarily mean water has entered the engine; it's commonly referred to as being 'choked out.' In this case, there is no need to worry. Once the water drains out, the engine can be restarted.
