What Are The Loudest Mufflers – Top 7 Explored

There are hundreds of different parts in a vehicle, and most times, drivers only know a few of them. While this isn’t a big deal, there are, however, some consequential parts that should be known.

One of them is the muffler – a vital part of a car’s exhaust system.

The quality of a muffler determines a truck’s engine performance, as well as its fuel consumption and sound.

In this article, you are about to discover the various types of vehicle mufflers and the loudest options available on the market.

What makes for a loud muffler?

As aforementioned, a muffler provides incredible benefits to your vehicle. However, it comes in different types.

When choosing a muffler for your truck, you need to consider these types as well as other factors such as fitments, style, construction, and category.

With these factors, you can determine what makes a loud muffler and whatnot.  

Find the Right Fit: Inlets, Diameters & More

The first factor you need to consider is the fitment. You need to choose the right fit for the best performance. And talking about fit, features such as inlet and outlet sizes or diameters are important.

The inlet size is the length of the muffler pipe where the valve is attached.

The outlet size is the length/size permissible by the valve on the outside to take the pipe.

If you want to measure the exhaust of your vehicle’s inlet and outlet, you need a few materials like a measuring tape and a marker.

The thing to do is to find the pipe’s circumference by using the measuring type. By doing this, you’ve found out the inlet’s diameter.

For the outlet diameter, you should divide your measure by pi (3.14).

Overall, ensure to check your vehicle’s make/model and choose the appropriate fit or option available on the market.

Choose a Style: Chambered vs. Turbo vs. Straight-Through

Another factor to consider is the muffler’s style. Generally, there are three known options – Chambered, Turbo, and Straight-Through.

Chambered Muffler

It has a unique operation as it allows gas to travel down a series of inner chambers to produce a deep throaty rumble.

This sound is a result of the reverberation of surrounding waves. Chambered Muffler is a perfect option for street and muscle cars intentional about producing strong sound.

Interestingly, the chambers’ size can be adjusted.

Straight-Through Muffler

The Straight-Through Muffler is a common type because it is made of sound-absorbing materials, i.e., steel wool or fiberglass.

It is a very loud muffler with no complication because it is literally a straight pipe and it freely allows gas to flow through. It is specially designed for performance trucks.

Turbo Muffler

The perfect hybrid is the Turbo Muffler. It has components of Chambered and Straight-Through Mufflers for effective performance. Here, this pipe comes with sound-deadening materials to reduce noise and allows gasses to move through chambers designed as S-shaped. It produces less noise.

Consider Construction: Aluminized vs. Stainless Steel Mufflers

Additionally, muffler construction is also important. It determines the performance quality and durability of the pipe.

Naturally Aluminum and Stainless Steel are varieties of steel but they differ from each other in appearance, thermal conductivity, strength, and cost.

Aluminized Mufflers are not as appealing as Stainless Steel Mufflers, but they have higher thermal conductivity and are cheaper. Stainless Steel Mufflers, on the other hand, are stronger and less likely to corrode but expensive.

Know what kind of muffler you need: Categories

Finally, the category of muffler is consequential. It determines the overall effect and quality of sound produced from the exhaust system.

There are only three categories – the cancellation, absorption, and diffusion.


Cancellation mufflers (also called Resonator or The Hemholtz Chamber) are designed with specificity to volume and length. When gasses enter from one end, a resonant frequency is created in a chamber where other sounds within that specific frequency are canceled.

Here, they only cancel one frequency in an exhaust. And most times, cancellation mufflers are used with absorptive mufflers.


Absorptive mufflers come with straight, circular, and perforated pipes housed in a large steel system.

And in between, there are materials that absorb sound, keeping the noise produced at the lowest minimum. They have the least resistance when exhaust gasses flow through.


Diffusion Mufflers divide the flow of exhaust gasses into various paths using baffles (a series of tubes and plates).

These baffles only increase the journeying length of the exhaust when passing through the muffler. Along the line, multiple sound frequencies are lost as a result of superposition and sound wave reflection.

What type of mufflers are the loudest?

Glasspack Mufflers are the loudest. They deliver the best performance and become aggressive with open pipes.

Glasspack mufflers work using a unique material, i.e., a sleeve of glass, that absorbs engine sound, thus dissipating sound wave’s pressure.

They are the perfect choice for race and off-road applications.
