4 Cylinder Muffler Buyers’ Guide

Best Sounding Muffler For 4 Cylinder

We have described the top muffler for 4 cylinders available in detail. But if you are still confused about which one to pick, read through our buyer’s guide which would make it easier for you to make the right decision.

Type of Design

Mufflers come in three designs.

Each design impacts your vehicle differently. The performance and the sound produced by your vehicle is directly influenced by the type of muffler that you choose.

Chambered Mufflers

As the name suggests, these mufflers have their inner space divided into sections, also known as chambers by using walls.

How does it work? These chambers are positioned in a specific way such that the sound waves interfere and interact with each other. And when this happens, these waves reduce one another’s sound effect, and as a result, reduce the sound created in the end.

Some brands also include additional inserts that line these chambers. This gives a further reduction in the sound created.

What does it sound like? Chambered mufflers make your vehicle sound quieter. And the arrangement of these chambers creates a certain exhaust note which is not very loud but gives a muscle roar to your vehicle.

Straight-Through Mufflers

These mufflers consist of a single tube that runs from the inlet to the outlet. It is usually a straight tube, though some brands have introduced an angular tube as well.

How does it work? This tube is packed with a perforated porous material to absorb sound. Some of the common material used includes fiberglass, steel wool, or premium quality cotton. These materials have excellent sound-absorbing properties and therefore, they reduce the noise that your vehicle will make.

Furthermore, the exterior of the tube is then covered with stainless steel which further reduces the sound.

What does it sound like? These straight-through mufflers give you a great choice. They can give you a loud enough sound to get noticed on the road. Some of these can make a raucous sound that can be too loud for your ears.

An advantage of these is that they improve your engine’s performance considerably. Since the exhaust is a straight pipe, the gases flow out quickly without facing much resistance. This greatly increases your vehicle’s performance and also makes your car efficient.

Turbo Mufflers

These are designed as a fusion of the two types of mufflers discussed above.

How does it work? They have the inside tubes twisted into an S shape which works as chambers or portions. In addition to this, the tube is packed with fiberglass or other porous materials just like the straight-through mufflers.

What does it sound like? The twisted tubes resist the flow of exhaust gases from the outlet. Thus, it takes longer for them to flow out, and in this process, their sound energy is reduced considerably. Therefore, turbo mufflers give you a quieter sound.

Which One Does it Better?

Good at noise reduction
Chambered and turbo

The Best Material

This is one of the most important considerations when evaluating a muffler. This is because it undergoes immense amounts of exposure and is subject to too much wear and tear.

In addition to this, it needs to be built strong enough to handle the intense pressure with which the exhaust gases flow through. Therefore, it should be made up of strong and durable material so it can last for a long time.

There are two types of material used in making mufflers.

Stainless Steel:Aluminized Steel:
Stainless steel wins over aluminized steel for various reasons:

First, it gives a shiny and gleaming appearance making the exterior look aesthetically appealing.

Second, it has anti-corrosion properties. This gives it a long life span and makes it resistant to all types of weather conditions.

Third, it is sturdy and strong enough to bear the pressure of the exhaust gases passing through the pipe.

Aluminized steel is basically a steel pipe that is covered with aluminum. Aluminized steel is less expensive than stainless steel so this is an advantage.

But it is not durable enough. It gets scratched after use for some time. And once the outer coating gets scratched, the steel inside gets exposed which makes it prone to corrosion.

The Right Size

When purchasing a muffler for your car, it is very important to know the size specifications of your car. You would not want to buy one and then not be able to use it simply because it will not fit in the space available in your car.

When checking the size of your muffler, consider the following checkpoints:

Check your car’s exhaust system – single or dual? A car with a single exhaust will be fitted with a muffler with one inlet whereas a dual exhaust car will be fitted with a muffler with two inlets.

Check the diameter of the exhaust pipe: The diameter of the exhaust pipe should be the same as the muffler’s inlet pipe diameter. Otherwise, the muffler would not fit.

Check the length of the muffler: You need to check how much space is available in your car for a muffler. Pick the one which is the same length as that of your car’s exhaust pipe.

Frequently Asked Questions

1. What is the difference between a 6 cylinder muffler and 4 cylinder muffler?

Mostly, a 4 cylinder muffler is better in terms of fuel efficiency. Fewer cylinders guarantee fuel efficiency. You can cover more ground in the same fuel as compared to a 6 cylinder one. On the other hand, 6 cylinder mufflers provide better engine output.

2. How to install a muffler without welding?

Other than welding, you can fit a new muffler by bolting it. In the first step, you need to jack up your car and remove the old muffler which is already installed. You can do this by removing all the clamps and bolts that are in place.

The next step would be to place the new muffler and fix all the clamps and bolts that came with your new muffler. Make sure you tighten all these bolts properly.

As the last step, check your muffler for any leakages. These can be identified by starting your car and carefully listening to the sound created. If it is too loud, that indicates a leak.

3. How to make a muffler louder?

You can make your muffler louder in three ways:

First, you can change the type of muffler already installed in your vehicle. Choose a straight-through or a glass-packed muffler because these have louder sounds.

Second, you can add an exhaust tip that has sound amplifying properties.

Third, you can make your exhaust pipe’s diameter larger.

4. Can you run your car without a muffler?

Not really! Most of the states have legal requirements and guidelines regarding the fumes and sound created by your vehicle. You need to keep these in mind to keep yourself away from being penalized.


After reviewing the best muffler for 4 cylinders, our pick is the Walker 53602 Quiet Flow Muffler. The reason for choosing this is that it gives you a muffler that is entirely designed using OE solutions. From bolts to hangers and even the welds – these are all built on the OE style.
