Why Is My Car Silencer Making Noise?
The silencer in a car's exhaust system is intended to lessen the noise generated by the engine.
It is positioned inline within the exhaust pipe and contains baffles as well as sound-absorbing materials such as fiberglass batting.
By entering the silencer, some of the engine's sound waves are reflected off the baffles, causing them to cancel each other out. Additionally, the insulating materials disrupt another portion of the sound waves.
If there is a loud exhaust noise, it usually indicates that there is a hole in either a pipe or the silencer box.
Is the car's silencer causing a rattling noise?
Over time, the muffler, exhaust pipe, and catalytic converter in a car can experience wear and tear, resulting in a rattle noise from underneath. If the joints in these components degrade and become damaged, they can gradually loosen. This can lead to the occurrence of a rattling sound emanating from beneath the vehicle.
