What Are the Effects of Water Accumulation in the Exhaust Pipe?

[McReagan]

Water accumulation in the exhaust pipe can have the following effects: Engine Water Intake: Water entering the exhaust pipe can lead to the serious consequence of water entering the engine. If only the exhaust pipe has water, it is essential to remove the accumulated water as soon as possible to prevent impurities in the water from clogging the catalytic converter or damaging the oxygen sensor. To drain the water, simply increase the throttle to expel the water through the exhaust. Engine Stalling: Water in the exhaust pipe may cause blockage, leading to poor exhaust flow and engine stalling. However, in this case, the engine may not necessarily take in water; it is just what is commonly referred to as "being choked out." There is no need to worry in such situations. Once the water drains out, the engine can be restarted.
