Things to consider before buying Exhausts:


Even if you are purchasing something as basic and uncomplicated as a handlebar, diving headfirst into the world of aftermarket components without doing any basic research is a terrible idea in any situation. But what about the more sophisticated components, such as an exhaust component, for instance?

Exhaust systems have the ability to make or break the functionality of your vehicle, which is why it is critical to be fully versed in them before making a purchase decision. As a result, we’ve put up a few pointers for Magnaflow vs Flowmaster muffler that we hope will assist you in making the best purchasing choice possible.

Size of the Muffler:


When purchasing an aftermarket exhaust, pay close attention to the size of the pipe. A larger muffler like the flowmaster 44 will be required if you want to get the most out of your car’s performance; the size of the muffler will also affect the level of noise produced by the exhaust system. There is a simple guideline to follow in this situation: the larger the muffler, the quieter the exhaust will be.

Choose Between H-Pipe and X Pipe:


If you are stuck between purchasing an X exhaust pipe and an H exhaust pipe, evaluate whether you want a high frequency or a richer tone from your car when you make your decision. Their respective performance outcomes are identical; the only difference is that the former characteristic applies to the H pipeline and the latter to the X pipe, respectively.



Do not increase the size of the tube without first talking with a qualified professional. In addition, bear in mind that if you have a car with less than 250 horsepower, 5cm tubing will be enough; however, if you have a street-legal vehicle, 6.30 cm tubing is recommended. Purchase 7.5cm tubing for those if you’ve got a 500HP engine for the best possible performance.



Your exhaust should be constructed entirely of stainless steel. Stainless steel is long-lasting and keeps your exhaust from corrosion. This type of exhaust system is costly, but it should endure for a long period. When your vehicle drives through water, one of the materials to come into touch with the exhaust system is water.

Look for a 304 or 409 stainless steel exhaust system to achieve long-lasting performance and keep your exhaust from rusting. Although 304 is a better quality stainless steel, 409 is more often utilized in exhaust systems.



Checking to see whether your installation kit has all of the essential components is also extremely important since you don’t want to wind up having to purchase more clamps or a screw because you were missing one. Check the kit thoroughly to ensure that it has all of the parts and tools that were specified in the description. For example check to see whether you have all the parts to fix catalytic converter in the future.

Compatibility With Your Car:


If you are not planning on racing, you should go for a more conservative exhaust since, when it comes to exhausts, less is more when you are driving your vehicle on a daily basis. The fact that not every exhaust system will definitely increase your engine’s horsepower is something you should bear in mind while shopping. Not only that you should also make sure that kit is easy enough for you to replace an exhaust on your own.

Frequently Asked Questions:


After reading our reviews, following the muffler replacement instructions, and looking through the Flowmaster vs Magnaflow comparison part, you must still have a few questions that need to be answered.

This section is intended to solve that problem. Here are a few questions and their corresponding answers that you may find interesting:

Q: What does an exhaust actually do?

The exhaust is an extremely important component of the vehicle. People who are unfamiliar with cars believe that the exhaust system sends smoke and sound from the engine out the rear of the vehicle, which is somewhat right.

The primary purpose of the exhaust system is to provide a pathway for the engine’s exhaust gases to exit the vehicle. To link to the engine’s exhaust manifold, a system of pipes is installed below the car and exits from the rear.

Q: How long does it take for both exhausts to reach a consistent sound?

Because of the Magnaflow’s straight through mufflers construction, it might reach up to 400 miles until you notice a stable sound quality. Magnaflow aftermarket exhaust will produce a very loud exhaust sound because the straight-through type is the least efficient at suppressing noise. Since Flowmaster has a chamber-style construction, the muffler noise should be constant from the start.

Q: Do Magnaflow exhausts help you get more horsepower?

Although upgrading a new exhaust alone may not provide the horsepower boost you need, replacing your vehicle’s whole exhaust system with a Magnaflow system most certainly will.

Q: What’s the difference between Magnaflow vs Flowmaster in terms of noise?

A single exhaust system may boost the performance of your car by around 2 percent to 5 percent. It is possible to get up to ten percent more horsepower by installing a full Magnaflow exhaust components.

Q: Will the sound of Flowmaster exhausts get louder over time?

Because Flowmaster exhaust systems have a chambered design and do not include insulation, the inside is more prone to break down with time, resulting in a louder sound.

The same thing may happen with a Magnaflow, but it’s less probable since they come with a proprietary core that doesn’t break down as quickly as other types of cores.

Q: Is it possible for a Flowmaster exhaust to enhance MPG?

The MPG (miles per gallon), often known as miles per gallon, relates to the vehicle’s efficiency. It is true that it may be influenced by the addition of a number of components that boost engine performance.

In such a scenario, the proper exhaust system, such as the one offered by Flowmaster, might be beneficial. When using an exhaust system, you should expect an increase in efficiency of up to 5 percent.

Q: Is Magnaflow a high-quality exhaust system?

It’s been more than 50 years since Magnaflow systems began making high-quality exhaust systems and mufflers for the automotive industry. They are well-known for providing good sound quality and exceptional outcomes at a higher cost than other organizations.

Q: Is Magnaflow quieter exhaust system?

The sound of the Magnaflow exhaust is really faint at first but then it converts into tuned sound as it begins to condense. It’s an excellent method of optimizing performance since you can hear how your engine is doing as it runs.



Even though both Magnaflow and Flowmaster exhaust systems provide significant performance improvements and have tuned sound, the choice ultimately boils down to what you’re looking for in an exhaust pipe and how much money you have to spend. Because of the wide range of sound characteristics available, opinions on exhausts are also extremely subjective, so be sure to check out this Magnaflow vs Flowmaster review thoroughly and make your decision!
