How Often Do You Need To Replace A Muffler?

The muffler is an integral part of the exhaust system that minimizes the noise produced during the exhaust process. The muffler also directs the exhaust out of the vehicle. This means a defective muffler doesn’t only make a lot of noise, it also causes very real issues for the driver and the passengers in the vehicle. So be sure to have your exhaust system checked by your auto mechanic periodically to ensure it is working properly.

Making repairs to the exhaust system can sometimes be rather expensive depending on the make, model, and general condition of your vehicle, neglecting a needed repair is not advised. Not only can the cost of that repair work increase, but it could also develop into more serious problems for the people in the vehicle.

But how often do you need to replace a muffler?  Just remember that mufflers are like most other auto parts—they wear out over time.  So be alert to some of the signs of a muffler that is not functioning correctly: 

• Listen up! The biggest and most noticeable sign of a bad muffler is the noise. When your muffler fails, the car will suddenly seem a lot louder than it did before. Be especially vigilant for any strange or sudden rattling noise, which could be the sound of a muffler that’s become loose.
• Look at it! Ask your auto mechanic to raise the vehicle and visually check the muffler. Any major problems, such as holes, are generally easily noticeable.  Also, inspect for any signs of water dripping from it. A bit of condensation is usual, but water leaking from some places on the muffler is definitely trouble.
• Check the temperature.  Turn on the motor and let it run for a few minutes.  If the temperature rises abnormally high, it can cause the vehicle to overheat.
