best muffler brands

A muffler is a must-have part of the exhaust system. It can contribute to dampening the noise caused by the engine. Thanks to this, both inside and outside of your vehicle are more tolerable and comfortable.

Besides this, a muffler can regulate the engine’s backpressure to maximize its efficiency and performance. You can also use a silencer as a tool for your vehicle to show some personality from the exhaust’s noise.  

If you don’t know how to choose which model is the best for your vehicle, then this article is just perfect for you. I have reviewed the nine best mufflers on the market and a buying guide for you to follow.

Factors to Consider When Buying Best Sounding Mufflers

1. Material 

When you buy a product, the material is the first thing that you should always think of. There are two commons on the market now:

1.1 Stainless steel

This material is very durable. But you have to make sure your content is high-quality. It is compatible in a humid or wet environment. It avoids rust and lasts very long

1.2 Aluminum steel

This material is even more durable than stainless steel. If the humidity is not your worry, then go for this one. Aluminum can not corrode that quickly, either. So dry weather won’t affect your product either.  

2. Size

The second criteria that you should look at are the size of your muffler. You should purchase the right size. The product you are buying can not exceed the muffler’s length of your vehicle. You should check the inlet and outlet diameter too. Otherwise, you will have to buy an adaptor to set up.

3. Sound

You should know well what your car type is like. What is your purpose for buying this muffler? If you want a product for your race, then mufflers that don’t own many baffles are suitable. They can create more sound. The more restrictions are given, the more challenges your engine will meet.

But if you want to set up for your family car, then one that can offer silence is better to consider. 

4. Warranty

Either you pay a lot of reasons for a muffler, you have the right to check the warranty policy. Mostly, famous brands provide customers one year of warranty. But maybe you can find some other mufflers with a longer warranty time. Then you are fortunate!

5. Impact

The impact of a muffler is shown directly through the engine. They are well connected with each other. If you want to reduce the effect of backpressure, you can choose some that naturally do that. Or you can just pick some others to deal with the impact on their engine. The second way is more costly, but it is safer.

6. Brand 

There is a wide range of products on the market recently. It is essential to check the reputation of the brand that you are buying.  Some people don’t prefer a no-name muffler to be used in my car.

But there are cases that not-very-famous brands offer high-quality products too. Some people are not picky about this. They are excellent with whatever names, as long as the muffler works well. That is cool also.
