How to Make a Muffler Quieter

You feel refreshed while riding a car with cool music. Your comfort gets distracted when the engine sound interferes with your peace and that of other people. In some states, police will stop your car and arrest you for noise pollution. The muffler comes in handy to reduce noise pollution from the engine.

A car can produce excess noise for various reasons. An old car is likely to have rust in the exhaust pipe, especially if it lacks proper maintenance. Rust causes exhaust pipe leak, thus a loud noise. Cars with powerful engines or exhaust problems also produce a loud noise.

How to Make a Car Exhaust Quieter? (5 Ways to Quiet an Exhaust)

The cost of fixing the problem will depend on the cause. You can fix minor issues without involving professionals. But there are issues where professional help is necessary. Read on to learn easy ways of making mufflers quieter. They include

1. Fix The Leak – The engine produces dangerous fumes that can easily damage it. The exhaust system helps to remove them from the engine. After leaking, they remain in the engine while some leaks in the car. The noise reduces the engine efficiency, thus forcing it to work harder. That results in the engine producing a loud noise.

The dangerous gas leaking in the cabin is life-threatening. Sleeping in a car that is idling is dangerous If there is an exhaust leak. When driving, ensure that there is a free circulation of air.

Get a heat wrap tape to seal the holes in the exhaust pipe. A heat resistance Epoxy will also help you deal with leaks. Consider replacing the entire system if it has large holes.

2. Change The Muffler – The muffler should reduce the engine’s excess noise—unfavorable conditions such as salty areas and snow damage it quickly. Prolonged use also reduces the efficiency of the muffler. Once you detect problems with the muffler, replace it immediately.

3. Clean Muffler – Accumulation of rust on the muffler will result in loud noise. Failure to deal with it immediately causes leaks and damages to other components. Scrap the accumulating rust on the muffler before it causes further damage. Clean the muffler thoroughly and once through, start the car and feel the difference.

4. Install The Silencer – Another effective solution is combining the muffler with the silencer. Remember, the exhaust pipe with a large circumference will produce louder noise. The silencer reduces that circumference, thus limiting the air originating from the engine. Get a silencer that fits the dimensions of your car. The silencer is affordable and provides a faster solution to the noise. It’s easy to install so long as you follow manual instructions.

5. Use The Right Gas – Reading the owner’s manual and following instructions saves you from many hassles. But ignoring things like the type of gas your car requires will result in many issues, including loud exhaust noise. Assuming you have been refilling the car with regular gas, and yet it requires high octane gas. Don’t get surprised when the car starts producing a loud noise.

What Makes an Exhaust Loud/Noisy?

It’s okay for people to turn their heads to admire the beautiful model of your car. You feel confidence and some pride overflowing. The challenge comes when people look at your car with disgust and cursing due to excess noise. So, why should your exhaust produce much noise? Check the reasons below.

a. Damaged Muffler – Engine heat, poor weather conditions, and rust affect the lifespan of the muffler. Once it starts failing, it becomes ineffective, thus resulting in loud noise. Rust accumulates in the muffler over the years, causing leaks that can be dangerous to your health.

b. Leaking – Another main cause of noise in the exhaust is leaking. Remember, the car gets exposed to many things, including unfavorable weather conditions and rust. Sometimes traveling on rough roads may cause some damage to the pipe causing leakage. You should immediately address this issue; otherwise, it will damage other components in the exhaust system. Such components include

Catalytic Converter
Among the gasses released during internal combustion includes carbon monoxide hydrocarbon, among others. They are harmful to human health if released into the environment. This device turns them into less toxic gas before they pass through the exhaust pipe. Once damaged, it will produce a smell of rotten eggs, and a dark smell will appear. The engine gets slugging causing some loud noise. Other components that get damaged and produce loud noise include; the Front pipe and manifold gasket, among others.

Exhaust Noise Changes and What They Mean?

Understanding various exhaust noises will help you deal with the problem easily. Below are a few exhaust noises and their causes

a. Whirring

Belt-driven components and the pulleys are major culprits when it comes to a whirring sound. If the belt is tight and the pulley is okay, then check these components. They include the alternator, power steering pump, and water pump. Other culprits include the radiator fan and serpentine belt.

b. Hissing, Sizzling, Or Gurgling

Steam from the radiator cap produces some hissing sound. The excess pressure from the boiling water in the radiator produces a gurgling voice. The effects of coolant once the engine overheats cause a sizzling sound. If the car starts producing these sounds, followed by a bad smell, it means some engine components have worn out. Check and repair or even replace such components to avoid further damage.

c. Loud Exhaust Noise

Is the engine tone much deeper and loud? Leaking in the exhaust pipe is the main reason. Other symptoms include odor, reduction in engine performance, and reduced acceleration. Failure to repair will lead to damaging other components such as the EGR valve, muffler, and catalytic converter, among others. Damaged components worsen the situation.


Q: What Causes Engine Backfiring?

A: Diagnosing the exact cause of backfiring can be a challenging task. Professional engineers have come up with a few reasons why backfiring may occur. They include water that leaks into the combustion system; it may occur if the fuel has some water. Another cause of misfiring is damaged components in the engine.

Q: Why Is My Car Producing Sputtering Noise?

A: If the engine is producing an inconsistent harmonic sound, then it has incomplete combustion. The main cause of this problem is ignition timing problems.

Q: Why Does My Exhaust Produce A Burning Smell?

A: A new exhaust will produce some burning smell courtesy of the oil left on the metals by the manufacturer. The smell won’t last forever but will end after 100 miles.

Q: Are There Universal Exhaust Systems?

A: Some exhaust systems are universal and are okay with any car. But some are specifically designed, so be careful when purchasing.
