1. Lots of Gas

Gas prices are rising lately, and if you feel like you’re spending more than usual, you’re not crazy. But if you’re spending more time at the pump than ever before, you could have a problem on your hands.

A muffler should help you get good gas mileage, but if you’re going too often, you might want to take a look.

Of course, bad MPG could be a number of things. However, if you’re already worried about your muffler, this could be a good diagnosis.

Keep in mind that, as a car ages, you should see worsening MPGs. A bad muffler will cause a serious drop, not just a few miles. 

2. Loud Sounds

Chances are that you know what your car sounds like when it’s in good shape. But if it starts to make an odd noise, there’s a good chance it could be the muffler!

This is one of the most obvious signs that you’re having a muffler problem. You’ll hear quite a bit of loud noise if your muffler is failing. 

If you hear rattling, take a look at your muffler. It could be broken or damaged, and the whole muffler might fall off if you don’t check soon. 

This isn’t the worst possible option, as it can be fixed. Plus, it should be quite evident, so you’ll be able to fix it in no time. 

3. Funky Smells

If you’re driving around and start to notice a bad smell, you should get to a mechanic as soon as possible.


Those funky smells could be evidence that your exhaust system isn’t working. If the exhaust can’t escape while you’re driving, it will get stuck in your car. This is why you can smell it. 

This is much more dangerous than it sounds, and it can, in fact, cause a fatal injury if you don’t get it fixed. Those exhaust fumes are toxic.
