Car's damaged muffler should have been replaced
he exhaust system of a car is composed of several parts, starting from the source engine, followed by exhaust manifold, three-way catalytic converter, main muffler, auxiliary muffler, etc. The most problematic of these is the muffler, because it is particularly susceptible to corrosion by car exhaust. If the muffler is damaged,

Classification of car mufflers, how many types of car mufflers
Resistant muffler Resistant muffler is when various mufflers such as expansion chamber and resonance chamber are composed of pipes, baffles and other components inside, the sound wave will be reflected and interfered during propagation, and the sound energy will be reduced to achieve the purpose of muffler. Resistant mufflers have a limited noise reduction frequency band, usually have good noise reduction effects on low and medium frequency bands, and have poor high frequency noise reduction effects. Most trucks use resistant mufflers.

What should I do if the car muffler is loud?
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.

What's the matter with the water dripping from the car muffler
Water dripping from the car muffler is a normal phenomenon, which is a sign of sufficient fuel combustion in the car, because after the gasoline is completely burned, water vapor and carbon dioxide will be generated. When the ambient temperature is low, the white smoke from the exhaust pipe is water vapor. When the water vapor As it flows through the metal pipe, it condenses into water droplets, which flow out through the small holes in the muffler.

What are the symptoms of a broken car muffler?
Because the main working principle of the muffler of a car is to reduce the noise generated when the engine is working. The principle is that the exhaust pipe of the car is composed of two pipes with different lengths. The difference in length is equal to half of the wavelength of the sound waves emitted by the car, so that the two columns of sound waves interfere with each other and cancel each other out when they are superimposed to reduce the sound intensity;

What is the difference between a three-way catalytic converter and a muffler?
When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote them to undergo a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature to become non-toxic. Color, non-toxic carbon dioxide gas; HC compounds are oxidized to water (H20) and carbon dioxide at high temperature; NOx is reduced to nitrogen and oxygen.
