The muffler is located on the rear part of the car's exhaust system, and its purpose is to reduce the noise that the engine makes. The muffler is made of steel and aluminium, which makes it resistant to high temperatures.
When the exhaust gas is released, it produces vibrations and sound waves which will generate the noise.
Inside the muffler, there are perforated pipes which will slow the flow of exhaust gases. The exhaust gases will pass through these pipes, changing direction several times, and finally leave through the exhaust. The perforated pipes are made in a soundproof material which will help to reduce the sound provoked by the passage of gases.
On some mufflers, the pipes are straight and composed of steel wool and fibreglass isolator, which will make the sound wave heat up. Then, the sound energy will be converted into heat, while the exhaust gas will pass straight through the muffler.
There are several ways to know if your car muffler is damaged.
In the event of a defective muffler, it will be necessary to have it changed quickly by driving your car to a mechanic.
Some car owners are handy enough to be able to change their car's exhaust muffler themselves. However, if you don’t have a minimum of mechanical knowledge, this operation can be complicated. We recommend that you let a mechanic do the replacement.
Before changing the muffler, you need to let the car cool down to avoid any risk of burns. Then, raise the car (check that the handbrake is on).
Dismount the muffler from the exhaust centre section of the car; to do so, loosen the screws on the silencer collar. You can then remove the muffler. In case of rust, you can use a rust release penetrant spray. Mount the new muffler, and place it by using the new screws. Make sure to tighten all the parts.
