The muffler is a very important component of your vehicle's exhaust system. The exhaust system has two main roles: one is decreasing the amount of noise the exhaust system makes and the other is to filter the exhaust gases coming from the engine. It is a part of your vehicle that you probably rarely think about, but if there is an issue, you should not ignore it.

The engine in your vehicle is loud because it produces a lot of power through combustion. Every time the engine’s cylinders ignite the air to fuel mixture, there is an explosion. There are about 1,000 explosions every single minute. This creates a lot of noise. The muffler on your vehicle helps suppress the noise. If the muffler is bad, your vehicle will become extremely noisy.

The muffler is positioned between the catalytic converter and the exhaust outlet. It is one of many components that work together to reduce noise. This process is called destructive interference.

Signs of Muffler Failure in Your Car

• Loud Exhaust Noise: The most common symptom of a failing muffler is an excessive noise coming from the exhaust. This noise is caused by a damaged or failing component. You may have a leaking manifold gasket, cracks, rust, or a hole in the muffler. Do not ignore a loud exhaust. The problem can hinder your vehicle’s performance and reduce your fuel economy.
• Sluggish Acceleration: If you notice that you need to press harder on the gas pedal to accelerate, you may be experiencing muffler failure. This is a dangerous issue that can lead to an accident.
• Strong Smell of Gas: When your vehicle is running, you should not be able to smell gas. If you can, there is a leak somewhere. This issue needs to be fixed right away. The fumes are poisonous and can enter the cabin of your car.
• Poor Gas Mileage: If the exhaust system is not working properly, your vehicle can burn more gas. This will produce a noticeable reduction in fuel economy. Poor gas mileage can be caused by a number of factors. If you notice that you are using more gas, yet driving the same amount, have our mechanics diagnose your issue.
• Exhaust Pipe is Hanging Low: Broken mounts, bent pipes, and rusting can cause your exhaust pipe to hang lower than usual. Do not drive your vehicle if the exhaust is hanging low. Continuing to do so can make the problem worse and the muffler can fall off.
• Knocking Sounds: Knocking noises coming from under your car can be caused by damaged exhaust mounts or a broken pipe.
• Rattling Noises: Rattling noises coming from under your vehicle can be caused by a loose muffler or component.
• Rust: Condensation buildup in the muffler and exhaust pipe and lead to rusting. Over time, the rust can completely eat through leading to failure. If you notice excessive rusting or condensation, it is time to have your muffler replaced.
• Misfires: All the components in your exhaust system work together. If any of the components fail, or the system becomes clogged, your engine may misfire.

Replacing Your Muffler

The average muffler has a lifespan of 40,000 to 80,000 miles, or around five to seven years. There are many factors that will lead to its eventual failure. These include everyday wear and tear along with driving conditions, road debris, weather and road salt. To help extend the lifespan of your muffler, wash the undercarriage regularly.
