1. Invest In A Quiet Muffler
The most practical approach to quiet a noisy exhaust is simply by investing in a good quality quiet muffler. This once and for good solution to reduce exhaust noise works because it covers the end part of the exhaust pipe right before the opening.
It achieves a quieter exhaust system but the only way to be successful in this method is by purchasing a muffler that is compatible with your vehicle.
If you are not sure which muffler will be right for your vehicle, you can ask your auto dealership.
We recommend the highly rated very quiet mufflers below:

2. DIY Exhaust Silencer Insert
In case you can not afford to purchase a premade silencer, you should think of getting a DIY exhaust silencer insert.
You can find numerous DIY tutorial videos online which explain how to design a silencer.
Most people opt for using a soda can, ball of steel wool, or a jar lid. These materials make an effective DIY exhaust silencer insert.
You just have to make sure that you completely understand what you are doing because the DIY methods can be risky.
3. Secure The Leak
If you want to silence a loud muffler but do not want to replace it with a new one, seal the leak. If your vehicle has a leak, the loud exhaust noise is probably due to the leaking puddle.
In order to fix the leak, start by covering the small perforations by using a piece of aluminum sheet. This piece should be bigger than the area of the leak.
Next, get a heat resistant epoxy such as J-B Weld HighHeat Degree Epoxy.
This epoxy acts as a sealant because it covers the patch.
If you want the best results, you can add an extra layer of epoxy on the aluminum sheet to solidify the patch.
But in case if the perforations are huge, invest in muffler cement.
We recommend the high quality Dynomax Muffler Cement.
You can also buy a tube that can seal the hole and avoid leaks effectively.
Be sure that before you install or apply any of these products, you need to wipe away the rust from the surface of the area which needs application.
If the exhaust is completely covered by holes, it is better to replace it with another exhaust.
Remember that these materials can silence a loud muffler as well.
4. Bring In The Silencers
If you want to know how to make aftermarket exhaust quieter, a silencer is very effective for this purpose.
An exhaust silencer is an affordable and practical method to soften the loud exhaust noise.
It is basically a plug at the exhaust and is installed via the exhaust tips.
The installation is super easy. You just need to create a hole in the exhaust tips in order to lock the silencers onto the exhaust system.
A homemade exhaust silencer is a good choice too but it requires more time.
Exhaust noise can be made quieter by applying exhaust paste like Holts Exhaust Paste and bandages too but this is more of a temporary solution.
What Makes An Exhaust So Loud And Noisy
In order to understand the reason behind a loud exhaust, it is important to know the science of frequencies and sound waves. All types of sounds can be classified into high and low frequencies.
A high-frequency sound is similar to a whistle whereas a low-frequency sound is like a thunderstorm. Low frequency sound is capable of traveling faster which makes it harder to absorb. This is the main culprit behind a loud exhaust which needs to be eradicated.
A homemade exhaust silencer, muffler, resonator, and silent muffler for a car can easily quiet a loud exhaust.
These tools work by manipulating the frequency and merging sound waves so that they strike out each other.
Other reasons why your exhaust is loud might be because it’s too powerful or old. A leaking exhaust might be a cause too.
If you want to figure out whether your exhaust is leaking, park your vehicle, and check out for any puddles or smoke coming from beneath the car. Having a hole in the muffler or a defect in the engine are potential factors too.
