If noise is coming from the muffler, it's time to replace

Mufflers reduce engine noise and filter exhaust. And in most instances, your muffler will let you know when it's time for a replacement.

If your muffler suddenly begins to make noise, it's a good indication there's a problem with your exhaust system.

Listen for rumbling or low-pitched rhythmic sounds while your car is in operation. This indicates you have a broken muffler that needs repair and should have a certified automotive technician examine the car as soon as possible.

Loud, abnormal noise indicates a hole in the muffler, although replacement should be carried out whenever there's any sort of damage or serious corrosion. Also, if your muffler becomes clogged, then you'll notice a loss of engine power. Replace your muffler immediately when:

• It makes a low booming noise, a rattling noise, or a hissing noise.
• The outside of the muffler is covered in soot.
• The internal separator rattles when tapped lightly.
• The muffler's exhaust noise becomes louder

Replace yourself or have your muffler replaced if it is broken. A broken muffler can allow exhaust to enter the passenger compartment, so it's important to keep your muffler in good repair.

Check to see if you have the correct muffler for your car. Especially if you have a used vehicle, the muffler may have been adapted to allow for more engine noise.

You may want to look into purchasing a more effective muffler, perhaps a performance muffler, if yours continues to be noisy after having the car inspected. Performance mufflers can improve your vehicle's fuel economy by helping the engine become more efficient. Performance mufflers offer significant advantages over competing mufflers, such as increased horsepower, torque, and fuel economy as well as lower temperatures, the source of these benefits comes down to airflow.
