A car's muffler connects to the end of the exhaust system. It is responsible for reducing the noise of the escaping engine gases, and after several years, it may deteriorate and require replacement. Knowing when you need an auto repair shop to install a new muffler can be difficult, and below are several indications to help you spot this. 

When Should You Replace a Muffler?

1. Loud Noises

If you have ever been distracted by the loud grumble of another driver’s exhaust system, this is because their car doesn't have a muffler or the component is damaged. If your car starts to make these loud rumbling or popping noises when you accelerate, the muffler is failing. This occurs because engine gases escape through cracks or holes in the manifold before they are filtered. These gaps form due to rust, which is common after exposure to road salt and other corrosive elements.

2. Strange Odors

By filtering the exhaust gases, the muffler prevents you, your passengers, and other drivers from inhaling toxic fumes. If you start to smell a burning or metallic odor when you accelerate, the muffler is allowing these gases to escape and enter the cabin. A cloud of dark smoke may also accompany the foul smell. Inhaling these fumes is dangerous, so stop driving and take your car to an auto repair shop as soon as you notice this issue.

3. Decreased Fuel Efficiency

In addition to limiting the sound and smell of the exhaust gases, the muffler helps the engine function efficiently. If the muffler experiences damage after you run over a pothole or speed bump, the gases can remain in the engine, altering the fuel and air mixture that powers the car. This forces the vehicle to use more fuel, reducing your gas mileage and requiring you to fill the tank more frequently. Replacing this component can help you save money and drive for longer periods.
