Magnaflow vs Flowmaster: Which Exhaust System is Better?

It can be challenging to decide between a Flowmaster vs a Magnaflow exhaust system. However, ultimately, it would be down to how much output you want — and, most importantly — the sound you want to achieve from your rig.

The upgrade of your exhaust system is arguably the perfect way to improve your engine’s power output, toughen up its sound, and even wear your outward look. All three of the advantages of premiere exhausts, of course, are given by Magnaflow and Flowmaster.

The brand you choose from will vary tremendously since each producer looks for another tone. Magnaflow and Flowmaster are two of the most common aftermarket production lines because of their distinct designs and tone. Both brands were established in the ’80s, and by now, they are one of the few brands with quality products.

Despite how useful they are, however, each brand comes with its own pros and cons. In this article, we will discuss which one is the right choice for you, so you can make an informed and decision on your truck’s exhaust system.

The Main Differences Between Magnaflow vs Flowmaster

The main differences between Magnaflow vs Flowmaster are:

  • Magnaflow and Flowmaster vary mainly in building and sound-canceling.
  • Compared to chambers by Flowmasters, the perforated stainless steel heart of a Magnaflow muffler does not have any flow constraints.
  • Magnaflow Systems are made of stainless steel, while most Flowmaster products use aluminum as the primary material for their exhausts.
  • The primary objective of Magnaflow is the development of exhaust components to optimize the vehicle’s efficiency.

Regarding the differences between Magnaflow and Flowmaster’s sound canceling abilities and construction, they are definitely notable. For instance, Magnaflow mufflers are straight and acoustically packaged around a perforated tube of stainless steel, while Flowmaster mufflers are constructed in a chamber format and do not use acoustic packaging materials.

It’s also true that the stainless steel center of the Magnaflow muffler bears no flow contraints. This means the exhaust gases are moving at average speed through the muffler. These mufflers are quieter than stock and provide more power to your engine.

Magnaflow vs Flowmaster

Its chambered nature produces a lovely grump in a Flowmaster muffler, as it slows down the gas exhaust. The chaos in a Flowmaster muffler is intended to create a scavenging effect to counteract this effect. The muffler has a consistent, well-tuned sound, but also has notably less power.

Finally, regarding Magnaflow’s efficiency, Flowmaster modules offer priority to reducing exhaust system noise. All in all, it makes for several notable differences between the two exhaust systems.

Frequently Asked Questions

Question: Is Magnaflow quieter than Flowmaster?

Answer: Yes, Magnaflow exhausts are more subtle than their counterparts. As already described, Magnaflow has lower sound levels than Flowmaster. While Magnaflow products have usually had subtle sounds, it may also happen that some Flowmaster products are better sounding. A Flowmaster with a performance orientation can sound as subtle as a Magnaflow display. However, Flowmaster typically offers the highest ones.

Question: Will Flowmaster exhausts become louder over time?

Answer: Yes, Flowmaster exhausts will become a little bit louder over time. This is because of the lack of insulation of chambered construction in Flowmaster exhaust systems, and the interior could break down over time and make the sound louder. It may be the same for a Magnaflow, but it is less likely that it would break down too quickly with its proprietary heart.

Question: Which among Magnaflow and Flowmaster has the loudest sound?

Answer: It’s quite evident from the specifications and rewiews that Flowmaster creates very loud exhausts, and some of the models are not recommended to use in the cities. Flowmaster specializes in making exhausts for racing and muscle cars, and because of this, they understandably ought to have strong sound. If you’re an owner of a muscle-car or someone who tries to make their presence felt with the loud rumbling sound, Flowmaster will be a great choice for you.
