When it comes to all of the essential parts that make up a car, not many people consider the muffler. However, this part is crucial to your exhaust system, as it reduces the sound of loud engines and helps increase your car’s performance. Below, learn more about the muffler and how to tell when yours needs to be replaced.

How It Works

When you turn on your engine, it releases pressurized gas that creates a lot of noise. Your muffler, which contains tubes that have lots of small holes in them, is designed to decrease that noise. The exhaust and its sound waves go into the center tube before reflecting off the back of the muffler and through the holes. The holes then lead to the exhaust pipe, ridding your vehicle of the loud noise and increasing your car’s efficiency.

Signs You Need a Replacement

Over time, your muffler can develop cracks or holes that will prevent it from reducing your engine noise as much as possible. If you suddenly notice loud noises when you accelerate, this is a clear sign your muffler is no longer doing what it's intended to.

Another key indicator is when the muffler gives off a bad smell. This car part filters out dangerous fumes that can be lethal, so if you start to smell them, you should get a replacement immediately.

Lastly, if the muffler isn't working efficiently, you may notice that your car is burning more gas than usual. Getting a new part will ensure your vehicle is filtering out the exhaust properly, which will restore your gas mileage to normal.
