Muffler Repair: Top 5 Practical Things to Know

Top 5 Things to Know About Muffler Repair

The muffler is one of the most important parts of a vehicle’s exhaust system. Its primary purpose is to reduce engine noise to an acceptable level. While most mufflers are designed to last for a long time, they can fail like any other car part. Here are the five key signs you need muffler repair.

1. You Smell Fumes
If you begin to smell gas fumes coming from your vehicle, this is a big red flag. We would advise you to get the problem fixed as soon as possible. The service technicians will determine whether muffler repair is required, which is why having your exhaust system inspected by a professional, is recommended.

Remember, a leaky muffler can allow carbon monoxide to creep inside the interior. Inhaling the fumes for long periods of time can cause you and your passengers to become sick. Crack open the windows to be on the safe side.

2. There’s A Lot Of Noise
When driving with a damaged muffler, do not expect your vehicle to run smooth and quiet. Engine noise will be noticeably louder than usual. Things can become especially ear-piercing when pressing down on the accelerator. Even if the extra clamor doesn’t get on your nerves, you still need to seek muffler repair. Raleigh has a noise ordinance, which means the police won’t hesitate to pull you over.

3. Your Gas Mileage Has Taken a Nosedive
When your vehicle’s exhaust system is not in good shape, fuel economy can take a big nosedive. Because there will be a loss of backpressure, the engine must work harder to compress the exhaust gases. This ultimately causes efficiency to suffer. After seeking muffler repair, many car owners notice a significant improvement in their vehicle’s gas mileage.

4. Car Performs Poorly
A damaged muffler can cause your vehicle to perform poorly. Don’t be surprised if you experience decreased power as well as slower acceleration. You may even notice that the check engine light has turned on. The car’s onboard computer can detect increased oxygen levels, which could indicate a hole in the muffler. By performing a backpressure vacuum test, muffler repair shops can tell if there’s a problem with the exhaust system.

5. Excessive Rust
It’s normal for a muffler to show some surface rust. However, severe corrosion should be of concern to you. It’s only a matter of time before the metal will be penetrated, which eventually causes the muffler to rot away. Routinely keep an eye out for rust spots along the muffler seams and tailpipe.

What Should You Do About a Bad Muffler?
In some instances, a damaged muffler will be fixable. Minor damage, such as small cracks and holes, can be welded up. If the muffler repair is too far gone, the only option is to have it replaced.

Some mufflers are as cheap as $20, However, the quality won’t be as good. You’re better off spending the money on a top-grade muffler that’s made of stainless steel. These types of mufflers can last for the life of the vehicle.
