Coming from Driven Performance Parts as a small branch for exhausts, it has been delivering high-quality systems for 38 years.

Flowmaster introduces exhaust systems of all kinds to the market. But they focus on loud rambling sound over all else.

Yet, these exhausts also help with other parts of the performance, including mileage and efficiency.

Considering how many years it’s been in the market, the vast popularity and respect it’s gained, and how well it works with most vehicles, Flowmaster is easily among the best brands you can go for.

That’s precisely what you get with the Super 10 muffler.

Maximum Loudness

If you’re weak of heart, then you should overlook this muffler.

DIY: How To Install Exhaust System

Now that you’ve learned about the best Magnaflow exhausts as well as the highest-quality Flowmaster models, it’s time to learn how to set them up.

This guide will be a little larger than you expect, so adjust your seatbelt.

We want to make it as comprehensive as possible, so you can set it up with small mistakes no matter the vehicle you have.

Here’s what to do:

01. Learn the Parts

First off, you should be well-aware of the different pieces that form an exhaust system.

As you can see, the most common part of an exhaust we reviewed was the muffler.

But other parts are also part of the system, such as the resonators and tailpipe (catalytic converter and oxygen sensors).

But you only need to know about the ones that are usually replaced and the ones you’ll probably work with: the resonator, muffler, and tailpipe.

The resonator is a long section that some exhaust systems have close to the muffler. It is usually enlarged.

Then you can find the tailpipe. This rounded part releases all the fumes and the one you see on most vehicle’s rears.

And lastly, you get the muffler. It looks either like a box or a thick tubing piece. Most mufflers are located between the tailpipe and the resonator (if any).

02. Prepare the Vehicle

By now, you should have a general knowledge of the pieces you’ll find below the vehicle. So it’s time to prepare it for installation/replacement. Follow these tips:

  • First, make sure the vehicle is cold. No need to put yourself in danger by removing a part of the exhaust when the whole system is scorching hot.
  • Raise the car with a jack. Use a jack and start raising the vehicle. Depending on the truck or car you have, you may need to raise the car by all its 4 wheels.
  • Use jack stands. A hydraulic jack won’t keep the vehicle stable enough for you to replace the exhaust. So don’t hesitate to use jack stands to add extra stability.

Once you’ve lifted the vehicle, then you’re almost ready to get it off.

03. Start Dismantling the Old Exhaust

You won’t be able to get the exhaust out right away. Instead, you’ll have to start by dismantling it slowly, piece by piece. Here are some things to consider:

  • Start by getting the oxygen sensors out. These are often located close to the engine. Be sure to follow your vehicle’s exhaust instructions before doing this. Use a ratchet.
  • Apply lubrication. Most of the nuts that keep the exhaust attached to the car will be either rusted or filled with gunk. So it may be challenging to get them out. Lubricate the nuts to make it easier.
  • Loosen up the nuts. Once a few minutes have passed after lubricating the nuts, you can start getting them out. Be sure to start by unscrewing the nuts close to the engine first.
  • Get the exhaust out. After you’ve got all the nuts out, the exhaust should get right out of the vehicle. Be careful not to bring the exhaust too harshly down, as it may secrete harmful gases or residues. Then you can dispose of it.

By now, you should be ready to install your new exhaust.

04. Prepare the New Exhaust

Here, you should be ready to get the new exhaust on and working. It is essential to consider a few factors, though:

  • Proceed, depending on the piece you have. If you’re installing an entire exhaust system (from sensors to tailpipe), then you only need to screw everything in. But if you’re installing only a muffler, resonator, or tailpipe, then you’ll have to do some cutting and soldering.
  • Check the hardware of the exhaust. Some exhausts don’t need to be screwed in on your vehicle. They are held by clamps or brackets. Make sure you know which one your car uses.
  • Find the front and rear parts. Some exhaust systems come with instructions. Read them up to find how the exhaust should go on the vehicle.
  • Brush the piece. Lastly, brush the front and rear area of the part. Make sure there’s nothing that could interfere with the installation before proceeding.

The exhaust system should be prepared for the nitty-gritty now.

05. Connect the Exhaust

Before you tighten up the vehicle’s piece, be sure it is located in the right place. Here’s a brief explanation of that:

  • Find the ideal place for the piece. Whether you have a tailpipe, a muffler, resonator, or a complete exhaust system, you should make sure it fits perfectly on the car. Try to insert it without tightening it up.
  • Connect it as needed. You can now proceed to connect it to the rest of the system as necessary. You may need to use some soldering to piece it up. Clamps and brackets also work in some cases.
  • Start by the front area. Try to connect the exhaust by the space that’s closest to the engine. This should make it easier to finish.

Once you’ve attached the exhaust completely, it is time to tighten up.

06. Secure the Exhaust

If the exhaust is already in place, then you must tighten it up. This should prevent any issue later on. For that, follow these tips:

  • Be sure the oxygen sensors are in place. Before putting the screws on, the sensors should be well-placed where needed.
  • Piece up the nuts & bolts. It’s now time to insert the nuts on their place and tighten up with the bolts. This should take a few minutes as you cover the exhaust.
  • Clamp or bracket the pieces. If you have small parts like resonators, tailpipe, or muffler, you need to clamp or bracket the piece instead of bolting.

Check that everything is sturdily located, and you’re done. It’s time for a test.

07. Test & Check the Installation

With the installation ready, there’s only one thing left to do: check that the exhaust works well. Here’s how to tackle that:

  • Try to move the exhaust. If the exhaust doesn’t move in the slightest when you try to agitate, it is sturdily tightened.
  • Start the car and check for leaks. Now you should start the vehicle. Be careful when doing so as it is lifted. You probably need to do it from outside. Then use a soapy water solution and apply around the areas you soldered/attached. Look for signs of bubbles or leaks and fix them as necessary.
  • Lower down the vehicle. If nothing is wrong, then take the jack stands off carefully (using the hydraulic jack, obviously), and you’re ready.

As you can see, this process should take you no more than a couple of hours with some experience. If you know nothing about exhaust systems or mechanical parts, then we recommend hiring an expert instead.

MagnaFlow vs Flowmaster: Factors to Consider When Buying

With a clearer idea of how Magnaflow vs Flowmaster differs in products, let’s now take a look at how they differ in specific factors about these products.

You will learn which one performs better in every individual point, going from construction to looks, and even warranty (plus anything in between). Take a look:

Construction & Durability

Let’s start with its build quality and materials. Here, the difference is not as much as you would like to make it an easy choice.

But it is noticeable enough so you won’t have to make a guess.

For example, you will find most MagnaFlow mufflers and exhaust systems to offer a straight-through construction with stainless steel acoustic cores.

Not to say that the core is typically perforated and adds to the quality of the piece.

Apart from that, Magnaflow uses stainless steel wool packing, which will last a lifetime in contrast with fiberglass and other materials that other brands use.

So you can expect exceptional resilience from Magnaflow exhausts.

Flowmaster doesn’t stay behind. You will also find them to have a quality stainless steel build.

This obviously ensures maximum sturdiness and resilience. But some of its models are not stainless but aluminized.

This may not seem like much of a difference, but aluminized wears out a bit faster.

They don’t have the same packing or core as Magnaflow. You will find typical steel constructions with no special build to sought after.

But they can handle most exterior factors well with their quality coatings.

Overall, we think Magnaflow exhausts are a bit more durable. This happens mainly because of its interior.

Sound Delivery

There’s probably nothing more important than the Magnaflow vs Flowmaster sound difference.

Both options deliver a more aggressive and deep sound than standard exhausts. But they are entirely different in sound quality.

For example, Magnaflow focuses on delivering a smooth sound that doesn’t ramble too much. The resonation tends to be moderate in most of its general designs.

This happens because Magnaflow is a dedicated silencer company. It creates unique baffles that reduce the potential sound exponentially.

The daily-driver exhausts also come with a low-pressure area that sucks a lot more exhaust power. Obviously, this reduces the overall noise your vehicle makes.

If you’re not looking to receive much internal resonation while still enjoying decent rumbling, then this is your choice.

The daily-driver models can be a lot quieter than you expect.

In contrast, Flowmaster focuses on the most aggressive sound possible. Some of its low-sounding alternatives tend to be pretty quiet (at Magnaflow level).

And it’s all thanks to internal baffles that reduce the noise a little.

But generally, Flowmaster exhausts are made to deafen people around almost as if there were no exhaust on the vehicle.

Muscle-car enthusiasts and people who love roaring cars usually prefer Flowmaster over Magnaflow because of that.

So, what are you looking for? If you prefer super-loud exhausts to wake neighbors, go for Flowmaster.

But if you are after something that minimizes the sound decently well without getting rid of the resonance, then a Magnaflow model will suffice.

Models & Types

When we talk about models and types, we refer to the different exhaust options available in both brands.

Here, you will learn about the many different products available on each and how they’re classified.

Magnaflow, for example, produces exhausts for all kinds of people.

Some models fit better with the typical commuter who drives around the city, but others work better for off-road and racing applications.

And to make it easier for buyers to get the right one, they classify their exhausts precisely that way.

  • Performance Series

The MF Performance series is the perfect addition for daily drivers. It adds a mild sound improvement but focusing on thin and light construction for a low-profile look.

  • Off-Road Pro

If you need an off-road exhaust, then the Off-Road Pro is the way to go.

It is lighter than the standard exhaust system but also a lot tougher. This design boosts up the sound of your truck exponentially.

  • Competition Series

For those who want to take their car to the next level in sound, the Competition series comes like a charm.

These are wider, larger, and usually with two tailpipes. The focus is to boost the sound coming from the engine as much as possible.

  • Rock Crawler

Most Rock Crawler exhausts are designed for Jeep Wranglers. But they’re totally worth considering if you’re looking to crawl some rocks (go off-roading).

The sound in this series is fantastic. Now it’s time to learn more about Flowmaster exhaust models.

In contrast with Magnaflow, they don’t separate them by application but by how they sound. Here’s how Flowmaster categorizes its exhausts:

  • Force II

The original Force exhaust system’s successor, the Force II, delivers a chambered design that provides a mildly aggressive sound.

It is made of stainless steel and works on many vehicles. You can find the Super 70 muffler in this exhaust.

  • FlowFX

For people who want maximum aggressiveness in the sound without losing legality (the ability to drive anywhere they want), nothing compares to the FlowFX series. It is where the Super 40 muffler appears.

  • Outlaw

Then you’ll find the Outlaw series. Here’s where the Super 10 muffler appears, delivering the most aggressive-sounding performance.

You can say the Outlaw is like having no muffler at all, but with the resonance that mufflers provide.

These are all the different types and models of exhausts you can find when looking for Magnaflow and Flowmaster.

As you can see, the difference is that Magnaflow focuses on the application, while Flowmaster identifies their exhausts by loudness.

Performance & Mileage

If you know a thing or two about exhaust systems, then you may be well-aware that they can also improve your mileage and overall engine performance.

Here, we compare how the Magnaflow vs Flowmaster performance differs.

There’s not much a difference, though. Both brands create Mandrel-bent tubing that boosts horsepower and torque.

This obviously ends up in up to 10% better engine performance.

But there’s a slight difference when you go to the most performance-oriented models. For example, Force II from Flowmaster focuses on improving flow.

It reduces gas consumption a little, which helps enormously with the mileage.

Magnaflow has the same system but on its more aggressive models.

So while you get slightly better improvement inflow for mileage on its loudest exhausts, the daily-driver models may not offer many advantages.

In this factor, it’s more a matter of preference than anything else.

Because the difference is not too significant between them, you’re likely not to find either one better than the other.

Looks & Design

We can’t overlook the appearance of the exhausts either. And here, it’s also a matter of preference.

For example, Magnaflow exhausts are usually platin-like tones. The mufflers are typically shiny with polished stainless-steel exteriors.

But you can also find black satin finishes, adding up to a varied set of exhaust appearance to consider.

Flowmaster exhausts, in contrast, are mostly black. They hold a traditional matte look, which is not really exciting but has a bit of rust protection.

Then you can find some of its cheapest models with a more silver metallic look, adding up to the variety.

So it truly depends on what you’re looking for. If you want a shiny-like appearance on your vehicle, then Magnaflow is probably your best bet.

But if you prefer something more low-profile, then Flowmaster would be the way to go.

Installation & Instructions

Nothing helps more when installing an exhaust system than a well-designed product that comes with all the hardware necessary (or at least matches with the factory parts on the vehicle).

In that case, both brands deliver excellent instructions, but a few things different.

For example, Magnaflow typically comes with straight-through designs that match with a wide array of vehicle’s factory mounts with their universal fit.

So you won’t need to make much of an effort.

Flowmaster also offers a similar experience. However, because the exhaust tends to be a little wider, they’re sometimes vehicle-specific, causing a few issues when installing.

So Magnaflow is a bit better. But the difference is not that much.

Warranty

Most people don’t consider the warranty the brands offer to be something worth considering because exhausts rarely break up or stop working.

But it’s still important to mention as both of these brands offer the same warranty: lifetime.

Yes, you read that right – these two excellent brands will focus on delivering maximum warranty in their exhausts so you can rest assured that they won’t steal your money.

Magnaflow Vs Flowmaster: Most Queries On Online!

After reading our reviews, installing the guide, and the Flowmaster vs Magnaflow comparison section, then you must still have a few doubts that need answering.

Well, this section is to relieve that. Here are a few questions with their respective answer you may want to take a look at:

Why get a Magnaflow exhaust?

Apart from the reasons you may come up with after reading the reviews and our comparison, we can say that Magnaflow is an utterly reliable company to buy from.

This brand produces exhausts that never let anyone down in almost any way.

Is a Flowmaster exhaust worth it?

If you’ve taken even a slight look into the exhaust market, then you probably found at least one or two Flowmaster models.

And it is not a surprise why – they produce the loudest exhaust systems out there.

If you’re a muscle-car owner or someone who wants to make their truck make an impossible-to-ignore sound, then Flowmaster is undoubtedly worth considering.

Do Magnaflow exhausts add horsepower?

Although adding a muffler alone may not add the horsepower improvement you may want, changing your car’s whole exhaust system with a Magnaflow system indeed does.

A single muffler may improve your vehicle’s performance by about 2% to 5%. With a complete Magnaflow exhaust system, you can get up to 10% in horsepower improvement.

Is Magnaflow quieter than Flowmaster?

Yes, Magnaflow is quieter than Flowmaster, as we already mentioned. But it also depends on the model you pick.

A performance-oriented Flowmaster will sound as subtle as a performance Magnaflow exhaust. But generally, Flowmaster produces the loudest models.

Will Flowmaster exhausts become louder over time?

Because Flowmaster exhaust systems don’t have insulation with a chambered construction, the interior likely to break down over time and produce a louder sound.

The same might happen with a Magnaflow, but it’s less likely because they come with their patented core that doesn’t break down as easily.

Can a Flowmaster exhaust improve MPG?

The MPG or miles-per-gallon refers to how efficient the vehicle. Sure enough, it can be affected by adding several pieces that improve engine performance.

In that case, the right exhaust system can help with that, which Flowmaster does. You can get up to 5% of efficiency improvement with a muffler.

Conclusion

After learning all about these two fantastic brands of exhaust systems, it is time to decide. And in that case, we can only help you with a brief comparison.

We can safely say that if you prefer a more durable and quieter exhaust system, then Magnaflow is your best bet.

You’ll still feel a slight rumble and resonance, and the right exhaust could add up to your vehicle’s appearance. So it’s completely worth it for the cost.

Then you find Flowmaster. It is perfect for those who prefer more rumbling and resonance.

The construction is excellent as well. Yet, the designs are a bit more limited and won’t fit on all vehicles.

But because they’re slightly more affordable, they’re an excellent budget choice as well.

So, what are you picking between Magnaflow vs Flowmaster? We know the choice may not be easy, so take your time to pick wisely.

Either way, you won’t be disappointed. Use our reviews to find the ideal model and you’ll never regret it!
