Help: What is the abnormal noise when the automobile exhaust pipe is hot?

1. When you step on the accelerator pedal, you will hear the exhaust pipe pop. The noise may not be very loud, and the car will not be abnormal when driving. Fuel consumption will increase, and the previous paragraph will sometimes make a similar sound.

Possible cause: It is recommended to check whether the muffler and exhaust pipe are damaged.

2. When driving at a low speed, or when refueling the door, there will be abnormal noise under the engine, especially when the weather is cold. It is recommended to raise the frame and check whether there is an insulation board between the exhaust pipe and the ground. It may be caused by the aging of the insulation board, which can be solved by replacing or removing it.

3. Abnormal noise when turning or moving forward. When turning, the common abnormal sound often comes from the broken joint of the front wheel drive shaft and the intermittent popping sound.

Possible reasons: it may be that there is a hole in which section of the exhaust pipe, or a part of the sheet metal or bumper has fallen off.
