Why Does My Exhaust Sound Raspy? (4 Reasons+Solutions)

Have you recently installed a new exhaust system in your car? Or is it possible that the old exhaust system is acting up and making raspy noises? 

As a result, you’re left thinking, why does my exhaust sound raspy?

There are a few reasons why your exhaust may sound raspy. It’s possible that the exhaust system has a leak or that the muffler is installed incorrectly. There could be an increased flow of exhaust gas or a small exhaust tip. Sometimes, it may be because you picked the wrong exhaust system for the car.

But what can you do to stop these raspy sounds? And is the exhaust system leak so serious that it must be replaced right away?

What if we offered to assist you in obtaining the solutions to these questions? Do you think that is a reasonable deal?

Good, let’s begin!

Why Does Your Exhaust Sound Raspy?

Exhaust repair is popular among sports compact fans who seek to increase horsepower. Because this transforms even the most mild-mannered cars into full-fledged sports cars. There are numerous aftermarket Exhaust packages to choose from.

However, many enthusiasts will learn that they can not simply just attach the exhaust.

Because after some time their exhaust will sound raspy when accelerating. There are a few other possible causes for this raspy exhaust noise as well:

Reason 1: Exhaust System Leak

An exhaust leak is often indicated by raspy engine sounds. Pay attention to a loud rumbling, especially as you accelerate. While the engine is operating, you can hear these popping or raspy sounds from time to time.

Incorrect handling of an exhaust leak could result in dangerous gases escaping into the atmosphere. Most of these dangerous gases have no odor.

They can be leaking into the passenger area without you noticing. Long-term exposure to these gases may cause you and your passengers to become ill.

Reason 2: Increased Flow of Exhaust Gas

One of the numerous benefits of the performance muffler is the improved gas mileage. This is due to higher exhaust gas flow. This muffler is normally mounted directly to your vehicle’s exhaust pipe.

The flow of engine exhaust gas into the inner cores is increased by a performance muffler. Unfortunately, this increased flow of gas creates a raspy sound from time to time.

Reason 3: Smaller Exhaust Tips

Smaller exhaust tips are another reason for the raspy sound. Your exhaust system can be finished off beautifully with exhaust tips. Throaty or raspy exhaust sounds can be achieved through these exhaust tips.

Exhaust tips complete the aesthetic of your car along with improving the exhaust systems. Your exhaust’s sound may change depending on the size and width of its exhaust tip.

Although these tips have a negligible impact on exhaust sound when used alone. But they enhance the sounds of your exhaust when combined with an updated exhaust system.

The sound will be throatier if the car’s tips are larger. Smaller tips, on the other hand, produced a raspy sound. The exhaust system on your vehicle may have smaller exhaust tips.

Reason 4: Wrong Muffler Placement

The basic function of a muffler is to minimize noise. But sometimes this role can be reversed. Muffler installation can cause problems with the exhaust system.

Any car’s exhaust system rarely experiences something like this. The positioning would have to be totally incorrect for this to happen. But a muffler placed incorrectly can create the raspy sound you hear from your exhaust. Readjusting the muffler into the correct position will easily solve this case

Any of these four options could be the source of the raspy sound. Check the exhaust systems and conduct a thorough inspection. This will help you determine which one is the source of the problem.

How to Fix the Raspy Sound Of Exhaust System

Now that you are aware of the potential culprit, you can silence the exhaust system’s raspy noise. Here are some tips on how to minimize these raspy noises

Fix The Exhaust Leak

Depending on the extent of the exhaust system leak, you will need to fix or replace it. If the leak is minor, putty and tape will be your saving grace. You can use putty to fill the small hole or tape it shut.

However, check if the leak is big or if any sections of the exhaust system are damaged. If they are damaged it is preferable to repair them in order to minimize future damage.

You should always inspect your exhaust system from time to time. Inspection of your exhaust system can help you spot and resolve issues before they become more problematic.

Pick the Right Exhaust System

In some cases, it seems that there’s no leak but the exhaust system is not working properly. Replacing the system with a more upgraded one is the best solution for these situations.

And while replacing the systems opt for one with large exhaust tips. This will also assist in eliminating the sound. Check out these exhaust systems, which have received a lot of positive customer feedback.

A four-cylinder exhaust is often one you can rely on to get the job done. You won’t have to be concerned about raspy sounds if you use these types of exhausts.

Install An Exhaust Resonator

Fortunately, another way to reduce the wasp is by adding an exhaust resonator. A resonator is designed to reduce engine noise when the exhaust gases flow through its chambers.

A resonator can give your automobile a sporty sound while reducing the raspy sound of the exhaust. Sometimes resonators are installed in premium cars in combination with mufflers to make the car smoother overall.

It is crucial to note that some states have regulations prohibiting you from changing your exhaust system. So before you install a resonator, check with the relevant authorities on your state’s emissions laws.

Install Glasspack Mufflers

You can also install glass pack mufflers to reduce the raspy sound. Glasspack mufflers quiet down the exhaust sounds through absorption. The exhaust will pass directly through your pipe if you use these mufflers. 

The pipe will have holes built in them for the exhaust to pass through. Glass insulation will be installed all around this pipe to absorb pressure pulses.

There will also be steel housing around the insulation. This will reduce the possibility of raspy noises.

While reinstalling this glass pack muffler, make sure to do the installation properly. Because wrong muffler placement can also cause a raspy sound.

You can easily purchase good glass pack mufflers in your local car parts store. Even Amazon has a notable selection of glass-pack mufflers.

The raspy sound coming from your exhaust is an annoyance. Hopefully, the remedies we discussed above may help you in reducing the noise.

When Do Your Exhaust Needs Replacing

Your engine may have to work harder than necessary due to exhaust leaks. It will reduce fuel efficiency and expose passengers to hazardous gases.

However, upgrading the entire exhaust system is a long and expensive process. You must be certain that the system is in need of replacement. Here are some tell-tale symptoms that a replacement is required.

Increased Engine Noise

This will be the first thing you notice. Because the exhaust system reduces engine noise, a leak will result in loud rumblings. Small leaks don’t make much noise, while larger ones make rumbling noises all the time.

Reduced Fuel Efficiency

Additional trips to the petrol station are frequently caused by an exhaust leak. The gases won’t leave the system if you have an exhaust leak. This will make the engine operate at a higher temperature and decrease fuel efficiency.


Unusual vibrations from the gas pedal and steering wheel indicate an exhaust leak. The entire car may even shake due to this if it is a big leak. 

If you suspect any of these issues, take your vehicle to repair straight away.


Why Is My Exhaust Sounding More Softer Than Normal?

A quiet exhaust indicates that something is obstructed, preventing sound and airflow from moving freely. Carbon buildup in a muffler, or faulty catalytic converters, might be behind a silent exhaust.

How Long Does A New Exhaust Take to Settle?

This is dependent on the amount of driving and the manner in which you drive. It will only take 1-2 weeks if you drive frequently and crank up the engine while driving. But if you drive frequently and don’t crank up, it’ll probably be a month. 

What Are The Effects Of Resonators On Exhaust?

The resonator reduces high-pitched noises as well as unpleasant hums and buzzes. Its purpose is to cancel out noises of a specific frequency that bounce off the device’s inside. The resonator smoothes out the exhaust note but has no effect on volume.

End Words

That’s all about why does my exhaust sound raspy. We hope our essay was useful in determining the source of the raspy sound.

If you are not sure of the reason still don’t hesitate to call the local mechanic. You can also take your car to one.

Good Luck and happy driving!
