Common Muffler Problems and How to Fix Them

Your muffler is constantly working to dampen and reduce sounds coming from your exhaust system. Since engines generate a lot of power, the process can be loud as the gases are channeled throughout the exhaust system, and they would be even louder if it wasn't for your muffler. The muffler is exposed to high levels of heat and pressure, so the metal can rust, crack, or puncture over time. 

If you're hearing louder noises, your car is misfiring, or your fuel consumption may be declining, among other problems, it may be time to check your muffler. While the muffler is expected to last five to seven years, there is no guarantee that it will withstand heat, pressure, and overwork. Performance Muffler experts offer some of the most common muffler problems and how to fix them. 

Your car sounds louder

Since the main job of a muffler is to dampen noise, most of the symptoms associated with a malfunctioning muffler are related to sound. When the muffler is damaged, you are more likely to hear a problem. If your car suddenly gets louder, it could indicate a damaged muffler or a leak in the exhaust system. You don't want to drive with this problem for more than a few days. 

Your engine is misfiring

Excessive damage to the muffler will cause the vehicle to misfire. Engine misfiring is felt as a temporary stumble or loss of speed, but the engine recovers after a few seconds. The muffler is at the end of the exhaust system, and when fumes cannot exit properly, it causes misfiring, often an indication that the muffler is not working properly to release fumes efficiently. 

Reduced fuel economy performance

A good exhaust system is the key to optimal vehicle performance. The muffler is often the fastest major exhaust system component to wear out. So, cracks or holes in the muffler interfere with the flow of exhaust gases. With reduced performance, your car will have worse fuel economy. When refueling, pay attention to whether your fuel economy has decreased.

While a bad or damaged muffler will make louder noises than usual, a weakened muffler will make more significant rattling noise under your vehicle. This is often the result of damage from minor accidents or problems under the vehicle, such as hitting potholes, which can damage the muffler. 

Bad smell from your car 

Since the exhaust gases pass through the exhaust system, they should easily exit the exhaust pipe after the muffler. If you smell exhaust inside or outside the car, it's most likely an issue with the entire exhaust system, but one part to look out for is the muffler. If the muffler has rust, cracks or holes, there is no doubt that it can emit fumes. 

How to fix a broken or bad muffler 

Unfortunately, the only recommended fixes for a faulty muffler are minor muffler damage. You can patch cracks or small holes with adhesive material that sticks to the surface of the muffler. Be sure to let the car sit for a while before attempting to fix any object with the exhaust system.
