Car's damaged muffler should have been replaced

2018-11-16

The 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, the car will make a lot of noise. So when your car has such a breakdown, how to repair it?

Some time ago, a car came to the auto repair shop, and it was a problem with the muffler. When the owner stepped on the accelerator to accelerate, the noise from the exhaust pipe was very loud! After a test drive, the auto mechanic determined that the fault was in the last section of the exhaust pipe of the car, as shown in the figure below! It looks fine on the outside, but as long as it shakes, there will be noise inside !
