Hearing a dripping sound from the front of the car after turning off the engine?

[GarrettAnn]

The dripping sound from the engine after turning it off is caused by thermal expansion and contraction. The exhaust pipe gets very hot while driving, and when the car is parked and the engine is turned off, the exhaust pipe cools down, causing the metal to expand and contract, which produces this sound. Here is some relevant information about car exhaust pipes: 1. Introduction: The car exhaust corrugated pipe, also known as the car exhaust flexible hose, is installed in the exhaust pipe between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. This helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust muffler system. 2. Classification: Exhaust pipes are generally divided into: standard OEM pipes, backpressure pipes, semi-backpressure pipes, and straight pipes.
