Best Mufflers Buying Guide

As in anything that you do in life, you want to make sure that you’ve done it right. This is the same for your muffler. It is a big part of your vehicle and plays a significant role in the performance of your car and the tone of the engine.

If you choose the wrong muffler, you can cause a lot of negative consequences for your vehicle, which can lead to even more issues that can be an expensive fix.

Mufflers reviews

Hybrid or Straight Design

A hybrid muffler design is a combination of baffles and perforated tubing. This is used to reduce engine noise. In a straight, through the plan, you have a perforated tube that goes from one muffler to the other. This is designed to trap the sound waves and make the sound stay in a layer of the packing material that is surrounding the tube.


Most mufflers are either made of stainless steel, aluminized mild steel or aluminum because this helps with durability. The best mufflers are made from stainless steel and are the better choice.

They are also considered to be the top end of mufflers because they look better, and they last much longer than the other material choices.

But, there’s a catch?

Due to their location, mufflers that are constructed of anything else are prone to rust and damage. This is especially true of ones that are made from mild steel, and the loss can happen in as little as four years, but with some brands, it can happen in as little as two weeks.

Universal Mufflers

These are sold as being able to fit on anything that has space, but as we’ve shown in our reviews, even some of the universal mufflers still have trouble fitting in a specific spot.

Noise Levels

The performance of the noise levels will also vary in range as well, and they break down into the following categories:

  • A Race Muffler
  • This is a muffler for high horsepower, and it usually has a straight through design.

A Performance Muffler

These have a more free-flowing design that boosts the noise of your vehicle and the power of your car.

A Standard Muffler or Stock Muffler

These are the mufflers that the factory has chosen for your vehicle, and they include chambers or cylinders that will cancel out the sound waves to a maximum degree. If you’re expecting more torque or more power, these are not the mufflers for you.

The Fit is Vital

Many people choose a muffler based on how they want their car to sound, but what you should also focus on choosing a muffler that’s been designed to fit your vehicle.

As mentioned in our reviews, a lot of the mufflers that say that they can fit a specific vehicle, do not! This is something that you want to avoid. There is no point having the best sounding muffler on the market if it doesn’t fit on your car.


This is obviously an essential consideration. You don’t want to end up buying something that you don’t like the sound of. The best advice is to watch some videos on YouTube and listen to how the muffler sounds for yourself. Bear in mind that you won’t get the low-end grunt of some mufflers if your listening on a low-quality sound system.

Size Matters

If you select a muffler that is too small or too large, it’s going to negatively impact the performance of your vehicle as well as the sound. These are two things you don’t want.

Thinking about all of the things listed above will help you make an educated and well-informed decision on which is the best muffler for you.

You can choose models that look good or sound good but ultimately whatever your choice is; you need to make sure that it’s right for you. The right muffler will improve your car. The wrong one will cost you money. This is the reason why its critical to get the decision right.

So, What Are The Best Mufflers?

Taking everything we’ve discussed into account, in our opinion, the best mufflers are the…

Flowmaster Mufflers

Every other option is compared with them in some way or another, and the company has a great reputation for quality products as well as for keeping their consumers happy.

They have quality mufflers and have fewer cons than the others on this list, as well as offering Delta Flow technology and MIG welding to make sure that they last longer for you and your car.
