Many car owners of vehicles with combustion engines don’t realize that their vehicle is always making powerful noises, just that they are silenced by the muffler.

Inside combustion engines, there are literally a million of explosions and chemical reactions happening inside the combustion engine of vehicles that gives it the power it needs to function.

They typically silence the motor, but sometimes car owners like to enhance the growling sound, buying custom-made mufflers that can produce even more powerful sounds; this video made by explains what mufflers are and the different types of mufflers that exist.

How Do Mufflers Work?

The muffler is part of the components of the exhaust system and is in charge of reducing the noise of vehicles that use combustion engines during the exhaust process; or in other words, they “muffle” out the moto’s noise.

Mufflers are tubes with chambers inside that cancel the noise of combustion engines by reflecting the sound waves created by them when exhaust gases and burnt fumes made by combustion enter the muffler.

The sound waves cancel each other similarly to the principle of noise-canceling headphones; here’s a video showing how mufflers work and cancel the noise.

What’s The Importance Of A Muffler?

Aside from reducing the noise produced by the exhaust process of all vehicles, the muffler is the final piece of the exhaust system that helps direct exhaust products out of the car.

This is very important because the vehicles with combustion engines make very harmful emissions which can get caught inside of the car, potentially provoking health issues, although breaking down these emissions is the work of the catalytic converter.

Also, the muffler works as a scape way, which directly impacts the motor’s performance and can provoke many problems if it gets clogged or damaged.

Their job is so essential that there are laws in all the states of America that require functioning mufflers on all vehicles driven on public roads.

When It’s Time To Replace The Muffler?

Mufflers usually last between 2 to 6 years or between 40,000 and 80,000 miles, and as with any other auto part, they wear out with time.

But mufflers can wear out prematurely or get damaged due to many reasons like the environment (car’s exposed to salty or wet environments) or due to driving habits (like being frequently hit by speed bumps or other road obstacles).

Which Are The Signs Of A Broken Or Damaged Muffler?

Several signs tell you the muffler is not working correctly and it’s time for repair or a replacement:

  1. Excessive noise from the muffler.
  2. Rattling.
