The 7 Best Aftermarket Exhaust for Mustang GT in 2023

There isn’t a shortage of exhausts offered by different brands. But we have our choices. In this article, we’ve reviewed the best 7 options you can consider as your exhaust system.

1. BORLA 140585 ATAK Cat-Back Exhaust System

Starting with Borla, a company that used to make parts for vehicles like Rolls-Royce and Ferraris. They are now available to use in your Mustang GTs as well. You’ll find that they are on the expensive side when compared to other exhaust systems. Why?

Firstly, because Borla manages to provide a high build quality throughout the product line. Each cat-back system, including this ATAK, is made with mandrel-bent tubing and austenitic stainless steel.

These are aircraft-grade steel, which is designed to have more corrosion resistance than other types of stainless steel. You’ll have durability for years to come.

If you don’t need to change your catalytic converter, then this ATAK cat-back exhaust is the perfect way to boost your Mustang’s performance as well as its sound. Borla uses mufflers that don’t restrict the path of exhaust gas airflow. That way, you get a nice-sounding car.

What are the improvements you should expect? The first thing you’ll notice is that you’re getting more performance for the same fuel consumption. Another benefit would be the nice sound it creates.

If you’re going to upgrade your Mustang’s exhaust, this is certainly a great option, especially for daily drivers. For sports car enthusiasts, you can look at other products on this list.

2. Borla 140017 Corvette Cat-Back System Exhaust

If you’re a Mustang GT owner and want a change in its performance and sound, then this “S-type” exhaust from Borla might be what the doctors ordered. That’s right, Borla’s exhaust features are also available for vehicles like Mustangs, Corvettes and other sports cars. And for such owners, price won’t be the issue.

The “S-type” designation in its name is from its mufflers. These mufflers are known for their balance in sound creation. The noise it makes is not too loud for the ears or too quiet to notice, it’s just right. What’s cool about it is that it also has an impact on the performance of the car.

Also, the components in Borla’s cat-back exhausts, including the mufflers, are made from the same aircraft-grade T-304 stainless steel. It makes sure that Borla’s million-mile oath stays protected.

The design features the famous multi-core technology from Borla that delivers better flow performance than your normal run of the mill straight pipes.

Regardless of the conditions you drive your vehicles, the exhaust performance remains the same throughout. You’ll also notice an increase in power generation, which results in higher torque.

The package includes a split angle-cut phantom tip for the rear. It’ll be a nice change in your vehicle’s look. With these features taken into consideration, Borla’s exhaust sound in your Mustang GT instead of the stock one does sound cool.

3. Borla 140428 Cat-Back Exhaust System

At number 3, we have another cat-back exhaust from Borla. This exhaust is Borla’s standard product when it comes to exhaust systems. It’s got all the best features Borla has to offer. But that also means it’s also one of the more expensive options you may find. The reasons are as below,

In terms of construction, there’s no argument against Borla’s choice of material. The T-304 stainless steel wins against the ordinary aluminized stainless steel builds. It’s an aircraft level material, so it should last you years before giving out on you. The color is silver, and the shine will remain there if you take care of it.

Then, the topic of exhaust sound is important for Borla. If you’ve been around the exhaust market, you know how Borla has made a name for its exhaust sound. It’s been dubbed as the best sounding exhaust for the 2017 Mustang GT.

The parts of this exhaust are universal, which means you can fit them either way. It makes installation easy. For those who love the visual aspect of having 4 tips at the rear, this exhaust system will impress them.

What about performance? Well, it’s been proven that changing your exhaust is one of the easiest ways to gain an increase in performance. And with Borla’s less restrictive mufflers, you should notice an HP increase in double digits. After all that is said, is it the best exhaust for Mustang GT? We certainly think so.

4. Borla 11806 Aggressive Rear Section Exhaust System

We talked a lot about Borla and how it maintains a top-notch quality in all its products. That was all about cat-back systems. How about a rear section ATAK exhaust, for a change? Will it perform in a Mustang GT?

This exhaust system from Borla bears “aggressive” in its name. For a Mustang, this sounds good. It gets this name from mostly its sound as well as from its looks.

Made from the same aircraft-grade stainless steel, this exhaust produces a loud sound that doesn’t irritate you, all the while keeping people’s attention on you.

The visual aspect of the aggressive ATAK exhaust will impress you. But if it doesn’t, there’s more to it than just aesthetics. It utilizes a multi-core and straight through technology. Thanks to these, it will provide more horsepower and torque.

Moreover, your engine’s exhaust velocity will increase. And you know what that means! More power for less fuel. It will certainly improve your fuel economy.

From its looks and feels, it’s evident that it’s a suitable fit for sports and performance cars such as Mustangs. If you’re going to buy it for a daily driving vehicle, this won’t be a good fit. It’s on the more expensive side as well.

5. Corsa 14332BLK Cat-Back Exhaust

If there’s a company that can compete with Borla’s quality exhausts, then Corsa would be the first among them. It has a good history of maintaining quality and trust with its customers, and that’s important when you spend hundreds of dollars on a single part.

With regards to the exhaust system’s design and construction, it’s the same T-304 stainless steel that we all know and appreciate. No matter what the road condition is, if you take care of it, you’ll get years of service from it.

This Corsa exhaust boasts a custom-tuned design that will add to your Mustang’s already robust looks. And with the stainless steel, the visual aspect of it will stay untainted for a long time unless you deliberately mess with it.

Then, let’s talk about the exhaust sound. Similar to Borla and other premium brands, Corsa also has emphasized on exhaust sound. It placed the patented Reflective Sound Cancellation design on improving the sound quality.

This technology removes unwanted sound reflections and gives a much clearer output. But the note is certainly aggressive for some people’s taste.

With a vehicle like Mustang GT, you’ll certainly love the aggressive note. But that’s not all this exhaust is good for because your engine will also get performance gains and a noticeably better fuel economy. It’ll also give your engine a longer lifespan.

Forgot to mention another feature of this exhaust system, and that’s the No Drone technology. You won’t experience that annoying monotone sound that happens in some aftermarket solutions.

6. Borla 140590 S-Type Cat-Back Exhaust

S-type exhausts from Borla are very well-known among people who use their Mustang as a daily driver, not as performance cars. These exhausts are not made for loud sounds to attract people’s attention. On the opposite, it’s for having a nice sound while not irritating the usual people around you.

This cat-back exhaust system has the S-type Borla mufflers with an elliptical shape instead of the cylindrical ones.

In terms of performance, there isn’t much of a difference, but the type of sound it makes varies from one to another. But don’t expect any difference in sound (dB) level.

Concerning the build quality and design, it’s the usual Borla’s signature. It has become a norm, but T-304 austenitic stainless steel keeps proving its worth.

You’ll drive a million miles with these on your vehicle without needing to replace them. It means, your Mustang won’t need to regularly visit the workshop.

There’s more to its design with its patented multiple core technology with straight-through design in its mufflers. It’s specifically designed to allow better airflow while maintaining little restriction on sound.

The pipe diameter is 2.5 inches with only 2 angle-cut tips at the back for letting our exhaust gases in the open.

It doesn’t look as good as compared to those exhausts with 4 tips. But then again, if you want muffled sound, having extra tips won’t be of much need to you.

7. Borla 140067 Cat-Back S-Type Exhaust

As our last product on this list, we have another S-type exhaust system from Borla. Through Movies, we are all accustomed to seeing Mustang GTs with loud sounds. But don’t be surprised when you see quiet powerful Mustangs. An s-type exhaust from Borla is a good match to such vehicles.

Borla’s sound is famous, we all know. But there are cases where you don’t want to have a loud sound spreading from your car but still have that feel.

Well, that’s why S-type exhausts from Borla also gained popularity. This type of exhaust doesn’t make a lot of sounds, but it’s not quiet at all. It feels just right on the ears, especially for a daily driver.

Borla’s long-time customers have at least one thing in common. It’s the appreciation for premium build quality in their exhausts.

With aircraft-grade stainless steel construction, your everyday road conditions won’t harm the integrity of its design. Durability, all of Borla’s exhausts have this thing in common.

If you’re after the visuals of Borla’s cat-back exhaust, you might be slightly disappointed. Because it has only 2 rear angle-cut tips instead of 4. It’s the down-side of having an ‘S-type’ exhaust.

But there’s nothing to be sad about Borla’s performance. With their patented multi-core and straight-through technology, your Mustang GT’s engine will have an increased life as well as increased performance thanks to better airflow.

Buying Guide: What to Look for Before You Buy Exhaust for Mustang GT?

Each type of product has some features that make it worthwhile. We used the same criteria to pick our 7 exhaust systems.

So, when you’re in the market, you should always be on the lookout for these points below. Let’s start with the types of exhausts.

Cat-Back or Axle-Back Exhaust System, Which One?

Cat-back is the type of exhaust system we chose for our list. You’ll see why they’re the better option. The exhaust gets its name from its connection in the vehicle. It connects to the system just after the catalytic converter.

When it comes to standard after-market exhausts, cat-backs are at the top. Although this type can be more expensive than, say, axle-backs, they’re longer and provides better airflow.

Cat-backs have X-pipe or H-pipe designs that are very popular with 2018+ Mustang GT models. They sound better than all other types.

On the other hand, axle-backs are the cheaper option if you want an upgrade in terms of sound and aesthetic. You won’t see any performance gain with an axle-back system.

Single Side or Double Side?

Single side exhaust system uses a single pipe to transfer all exhaust gases from the exhaust manifold top to the rear end of your vehicle and then into the open. It attaches to one side of the vehicle, which is the exact opposite of dual-pipe systems.

Turbo Back

If you have a vehicle that utilizes turbochargers, then a turbo-back exhaust might be of interest to you. It

takes the remaining exhaust gases from the turbo-charger and sends them outside into the open. Usually, performance car owners and drivers use this type of exhaust.

Pricing

Depending on the type of exhaust system and its brand, we divided the price ranges into three parts.

In the range of $100-$300, you’ll find single exhaust systems that are very basic. They only have pipes and clamps. Mufflers aren’t usually included here.

Then, in the range of $300-$500, you’ll find average cat-back and side systems. Most side systems will be the single exhaust system, with some dual exhaust systems available in this price range. They may include mufflers in different models.

Lastly, we have premium options. Their prices can hover from $500 to $5000, depending on the features and branding. All the latest and updated cat-back systems are in this range. As we mentioned before, for a Mustang GT, spending a thousand bucks is understandable.

Most top brands, such as Borla, Corsa, Flowmaster, etc., have products in this range. The best exhaust system for Mustang GT might as well be found in their product line.
