How to repair the silencer

In most cars, the muffler is installed on the exhaust pipe, its job is to reduce the noise emitted by the car engine to a low state. The muffler is equipped with perforated pipes or chambers with partitions. When the sound waves emitted by the engine enter the muffler, they will produce opposite sound waves. These opposing waves partially cancel out most of the noise. This component is strictly required to keep the vehicle at an acceptable noise level.

If you hear a very loud sound, like metal blocks touching each other, something may be touching the exhaust pipe. Loose brackets, rubber hangers or connectors or severe corrosion can cause this to happen. When the vehicle is accelerating or driving on a bumpy road, even when the car is started for the first time, it is stationary and idling. When the parts that connect the exhaust unit together fail, it can cause a misalignment in the system. When this happens, rattling sounds are common. If the vibration is caused by the muffler, it is likely to come from the rear of the car.

Once this happens to the muffler, it will cause excessive movement of other components and increase the pressure on these components. Therefore, if left untreated, it may not only be annoying noise. If the muffler is hung in a place lower than the normal level, it may be injured or damaged by jumping over the rails. Therefore, it is extremely important to repair the muffler problem as soon as possible.

Signs of muffler damage
If you suspect that your car is making a lot of noise due to a muffler problem, first look at your exhaust system. Although the common signal is rumbling noise, there are some other things to check. Look at the exhaust pipe under your car. Can you see rust or other damage? Pay close attention to the muffler itself and the heat shield. Are there obvious signs of damage? Also, pay attention to how your car operates. If you start to notice a decrease in efficiency, there may be a leak in the exhaust pipe or noise from the muffler.

Modern exhaust systems are usually made of aluminum-plated steel or stainless steel, but this does not mean that they or the parts that hold the exhaust components in place. Heat, debris, road salt, and moisture can all cause rust in the exhaust system. When your car has problems with exhaust, it is important to find a solution immediately. As time goes by, these problems will get worse, and the longer you wait, the higher the cost of repairing the car. When you have a damaged exhaust system, it’s not just the noise issue to consider: the rattle you hear may be annoying, but it may be a signal that your car’s exhaust is not properly flowing from your car In the discharge. Exhaust leaks can also make a rattling sound, and you may inhale exhaust gas from the damaged pipe.

Although the loud noise from the muffler can be repaired by tightening a few bolts or replacing a broken hanger, the corrosion of the muffler or surrounding parts may be serious enough and need to be replaced.

The noise or popping from the exhaust system may not be an external problem. The baffle or other parts inside the muffler may loosen and cause internal vibration.

In addition, there may be more than just the muffler. The brackets and bolts fixed on the exhaust pipe, the heat shield above the catalytic converter and other components may loosen, and the catalytic converter will generate internal vibration when it is broken.
