What should I do if the car muffler is loud?

2023-02-28

The loud sound of the car muffler is caused by the aging and damage of the rubber sleeve connected to the exhaust pipe or the damage of the structural pad connected to the exhaust pipe. Just replace it. The car muffler is a part used to reduce the noise generated by the engine of the motor vehicle. Since the length difference between the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two columns of sound waves interfere and cancel each other out when they are superimposed. Weaken the sound intensity and reduce the sound, so as to achieve the effect of noise reduction.

The method of replacing the rubber sleeve of the automobile muffler is as follows:

1. The loud sound of the exhaust pipe is caused by the aging of the gasket at the connection between the exhaust pipe and the engine;

2. Use a wrench to remove the screws at the connection between the exhaust pipe and the engine;

3. After loosening the screw, the exhaust pipe will be separated from the engine automatically;

4. Afterwards, take down the aging gasket, and disassemble the gasket;

5. Then put the new gasket on the exhaust pipe;

6. Tighten the screws with a wrench, so that the sound of the exhaust pipe is small.
