However, if you ask me, the appearance of an exhaust engine is just as important as its performance, isn't it?

Jeep JK Exhaust System

So, today we're going to take a look at the top 10 choices for the **best Jeep JK exhaust system.

to help you find the best one.

Why is the best Jeep JK exhaust system?

Even though the Jeep JK itself is a pretty powerful and heavy vehicle, if you're a true Jeep fanatic, you probably want to make your Jeep realize its true potential.

For this reason, getting the best cat-back exhaust system for your Jeep is the ultimate solution. Not only will it greatly increase the performance of your Jeep, but it will also turn heads wherever you pass from with its thunderous sound.

Our 10 Best Jeep JK Exhaust System Choices

I have gone through some of the top models from the most reputable manufacturers. After doing my personal review and reading customer reviews, I will tell you here the details of my top 10 choices and why I like them.

Also, I will mention their pros and cons so you can easily find out what you are looking for.

1. Flowmaster 817674 American Thunder 409S Exhaust System

If you are looking for the best Jeep jk exhaust system, no matter which review you choose to read, you will always find this product among the top choices. Let's see why.

First of all, the frame of this product makes it stand out from the rest, not only does it offer a very durable stainless steel construction, but it is also the most reliable when you consider it in the long run.

Fluke 817674 American Thunder 409S Exhaust System

So even if you are a rough driver, it won't have a very hard time not wearing out soon, making it perfect if you often find yourself off-roading.

Another thing that makes it quite suitable for off-roading is the high clearance that it has. It doesn't get hit easily and it performs much better compared to similar models.

Another thing that I really admire is the laminar flow technology. Now it may just be a technical term to you, but when put into use, it actually makes a big difference by increasing the airflow to a very desirable level. It's something that you would be hard pressed to see on any exhaust system.

However, there are some concerns that you should be fully aware of. First of all, the installation of this product is not the easiest and if you are inexperienced or don't know much about Jeeps, you may even need to consult a technician or someone with more knowledge, as the manual didn't really do it for me.

Pros

Heavy-duty, durable stainless steel construction

Mounts very well

No product has better cross-country clearance

Laminar flow technology works flawlessly

Cons

Manual is very difficult to understand

View Latest Price Bottom Line

If you're an expert installer and don't rely on the manual, this is honestly one of the best choices because it offers everything from durability, engine efficiency, and loud clearance.

2. Gibson Performance 17303-B Cat-Back Dual Split Exhaust System

The Gibson 17303-B is another top of the line product that impressed me. There are a few things I don't like as much. Let's take a look.

First, unlike the previous product we saw, Gibson actually provides you with a very detailed manual, which makes it very easy for the person installing it to follow all the instructions and achieve a problem-free installation finish.

Gibson Performance 17303-B Dual Split Exhaust System

At least, I didn't need any outside help and I hope the same is true in your case because you have a little knowledge.

Second, the sound. Man, the sound of this exhaust system really gives me goose bumps, and once you install it, driving your Jeep will never be the same. You'll know the difference when people passing by notice that you're driving this exhaust system.

However, you need to be aware that with the installation of this exhaust system, you have a vehicle that will completely lose its low end torque, something that everyone should know before installing it.

Now, one thing that really confused me was that even with this exhaust system installed, I hardly noticed any change in the acceleration of my Jeep.

Now, even though all the other purposes of installing it were perfectly fulfilled, I certainly hoped that acceleration would be improved with the expensive exhaust system installed.

If I had to choose my best option, that's probably why Gibson doesn't make the cut. But everyone has different needs, and that may not be as important to you.

Finally, since the system is a little more compact overall than other fancy exhaust systems, I didn't find it to be one of the most eye-catching. So, if you're not looking for great looks and acceleration, but can't compromise on sound, I'd recommend this product.

Pros

Manual is easy to follow

Gas mileage has been improved

Sound is great

No special cutting or welding tools required for installation

Cons

Not as fancy looking

Little to no increase in acceleration

View Latest Price Bottom Line

The Gibson 17303-B is a master at delivering sound and improving mileage, however, if classy looks and increased acceleration are what you need, it may not be the best choice.

3. MagnaFlow 15160 Exhaust System Kit

The MagnaFlow 15160 is one of my favorites and frankly, it's hard to criticize a product with such great quality.

If you look around for the best exhaust system, you tend to end up on this product because it is the best choice for most experts. Let's see what makes it worth all the attention!

First of all, durability is something we can't ignore when buying anything, let alone an exhaust system.

MagnaFlow 15160 Exhaust System Kit

Since these exhaust systems aren't cheap and you can't go back to them whenever you want, durability should be a priority when it comes to choosing one, and the MagnaFlow is built very strong to give you an amazingly long life.

When it comes to installation, you'll be very happy to know that the manual for this product is also very good, just like the last one we saw.

However, the installation gets further simplified because you only need a few tools throughout the process, and these are tools that not everyone usually has in their home. In my case, I only had to buy a torque wrench and a WD-40.

Now here's the best part, MagnaFlow has top of the line CNC manufacturing and is very precise and effective. There is no other product that gives you such precise measurements as this one.

Therefore, this product will fit your vehicle perfectly and you won't have any loose connection problems to bother yourself with.

Pros

Good performance even in cold air

Very precise fabrication and assembly

Precisely controlled manufacturing

It doesn't take a lot of time to install

Cons

Not a lot of off-road clearance

Some claims about wrong delivery

View Latest Price Bottom Line

The MagnaFlow 15160 is not one for off-roaders. However, performance is greatly increased along with a perfect fitment if they are at the top of your priority list.

4. Dynomax 39510 Axleback System

If you don't have a good budget and need to use something that won't leave a huge dent in your pocket, but you're not in the mood to compromise on quality, I would highly recommend this model to you. Let's see why!

First of all, I was impressed with the heavy duty body of the Dynomax 39510. At such a low price, you don't always see something very durable and shock absorbing.

Dynomax 39510 Axis Back System

In fact, the latter is what really surprised me. The product is designed with amazing fiberglass padding technology, which again is not just a term.

Rather, it is an amazing technology that brings vibrations down to a minimal level where they are almost imperceptible, at least to me. It doesn't look that great on paper, but trust me, once you get used to that, you won't find comfort in any other exhaust system.

The kit also comes with a much improved airflow system that utilizes a large tube that flows internally to help bring airflow to an optimal level. This tube, in addition to improving airflow, also provides better back pressure.

Installation is also a big thing that I pay close attention to in every product. Because, if someone can't easily follow the instructions and needs to call an expert, it obviously costs a lot of money.

Fortunately, this one doesn't require a lot of sweat equity to install; however, it's not the easiest one either.

The manual is pretty much all that's needed, but if you're a complete beginner, you may need to find some help online using the tutorials, mainly on YouTube, which is what you need most.

Pros

Internal flow tube provides optimal airflow

Very cost effective option

Minimal turbulence

Improved vehicle mileage

Cons

Not the most durable option

check latest price Bottom Line

Highly recommended for those looking for a heavy-duty and efficient product at an affordable price range. However, there are some trade-offs in terms of longevity.

5. Rough Country 96002 Dual Exhaust System

Next, we have another very affordable and value for money offering from Rough country. The company has established themselves quite a name for themselves when it comes to vehicle accessories and they have proven their excellence with this product once again.

For starters, this dual exhaust system comes in a very attractive matte black color that makes it very appealing to the eye.

Rough Country 96002 Dual Exhaust System

The 409 stainless steel makes it very durable and long lasting, so you never have to worry about the bodywork holding up over time, which is the number one preference for people like me who don't want to risk their money.

Secondly, the installation process seemed simple to me compared to some of the others.

The manual is detailed and explained in a very simple and intuitive way, and even if you get stuck somewhere, you don't need to consult any third party because the support provided by RC gets the job done. In addition, the design is perfectly fit and you will not need to do any cutting or drilling work.

When it comes to performance, I really like the high flow design of this one. Not only does it improve the flow in the exhaust, but the sound is also much improved and will have people turning their heads no matter where you pass by.

The chambered muffler is something that should be credited here for the amazing sound.

Pros

Very durable non-corrosive quality

Thundering sound even at low speeds

Very easy to install, no drilling required

Very cost effective

Cons

Sound becomes imperceptible at high speeds

Passenger side clearance is a bit small

Check Latest Price Bottom Line

The RC 96002 is a great performance booster and is recommended for those who don't have a lot of budget, but want to see them everywhere they go.

6. aFe Power 49-48055 Mach Force-XP Cat-Back Exhaust System

aFe Power is a well known company that has never let its customers down with its products, especially exhaust systems, and this one is no exception. If you are a big fan of off-roading, this could be a pretty good deal for you. Let's see how it goes.

aFe Power 4948055 - Exhaust System

First of all, as I mentioned before, if you often have to go through rough lots or hilly areas.

I highly recommend you take a look at this product because it has a Hi-Tuck design, which is specifically designed to deal with off-road clearance issues. It is quite tall and will not expose you to any problems.

The product is designed from high quality 2.5mm stainless steel tubing and you should not worry about any kind of durability issues as there are no reviews claiming any problems in long term use, which makes this product worth every penny.

Another thing that I really like about this exhaust system is that you will feel a very smooth transition after installation, riding your Jeep is different and you will indulge in the luxury.

It easily fits most skid plates out there and generally you don't have to go through any cutting or welding process, which is very convenient.

However, one thing that bothers me is that many of the usual customers claim to have leaks that are later solved with just a band clamp. Although this is not a big problem, you should keep this in mind just in case.

Pros

Sound becomes quite loud and clear after installation

Minimal turbulence

Great off-road clearance

Durable build quality; stainless steel muffler

Cons

Some claimed leaks

View Latest Price Bottom Line

Given its amazing performance and the benefits of off-roading, I'm happy to recommend this product, which has great airflow, the arrival of claimed defective leaks makes me have second thoughts.

7. Borla 11834 Rear Section Exhaust System

If you are a big fan of classic designs, this is definitely the one for you. The look on this is simply unbeatable and unmatched by anything else. However, that's not all it has to offer. Let's take a look.

The Borla 11834 has a 304 stainless steel construction body that showcases a very sleek and eye-catching look.

Borla 11834 rear section exhaust system

The shape is quite impressive and adds a lot to the beauty of your Jeep after installation; I have hardly met any customers who are not happy with the look, in fact, this is one of the biggest reasons why people choose it over others.

When it comes to performance, I have found this exhaust system to be very useful in increasing the productivity of the engine.

In the very short time I have been using it, I have noticed a big difference in my gas mileage, acceleration, and horsepower. This is not common, as many models do not juxtapose looks and performance.

Now, when it comes to sound quality, well, it's not the best, but it still exceeded my expectations as the product was already excellent in the other two areas.

The muffler that comes with this thing is custom made and provides good sound quality which makes you feel better when driving the Jeep.

However, if a heavy sound is a priority for you, you should know that there are other exhaust systems that can provide you with a better and louder sound than this thing.

Pros

One of the best looking exhaust systems out there

Custom Borla mufflers

Heavy-duty arbor style stainless steel

Improved Jeep mileage and acceleration

Cons

Not too loud

Check the latest price Bottom Line

The Borla 11834 is a top notch option with top notch durability and unmatched performance, I suggest you only get it if loudness is not the main thing you are looking for.

8. Red Rock Dual Outlet Axleback Exhaust

This is another top of the line product that caught my eye because it is a great all-rounder available at a very budget friendly price. Let's take a look at why this might be a good choice for you.

First of all, as I already mentioned, it has pretty much everything that one might expect from a top of the line exhaust system at a very affordable price.

Red Rock Dual Outlet Axleback Exhaust

Most of the time, people don't have a huge budget but don't want to compromise on the specifications. So, if you are one of those people, I have good news for you.

First is the installation. For me, I'm pretty much an expert with a lot of practice and it took me at most 15 minutes to complete the installation part without any outside help.

The manual alone did it for me; however, I needed to have some of the less common tools like the WD 40 and locking wrench. So, even if you are a beginner, you can expect to complete the installation in less than an hour.

Now, the sound. Well, I never knew what optimal sound levels meant until I used this model. Some products were so quiet that they went unnoticed, and some I had previously tested were too harsh for the ears of family members you might be sitting with.

With this system, however, the sound is just about perfect, and while you can brag all you want, you won't disturb or annoy anyone with the sound.

Finally, it has a very durable and heavy-duty stainless steel build quality, which won't bother you at all in the long run. Its finish makes it further resistant to any form of corrosion and rusting.

Pros

Good build quality and very long life

Very good sound quality, not too loud or too quiet

Elegant satin black finish makes it attractive

Very good value

Cons

Installation is not perfect

Check the latest price Bottom Line

If you have a family Jeep, you honestly can't get a better product in every way. You just need to take the time to put this thing together perfectly.

9. Pypes Performance Exhaust SJJ21R Cat-Back Exhaust System

Pypes Performance Exhaust SJJ21R

While it may not likely be the best choice if you are very interested in something to enhance the look of your car.

If you are a fan of high clearance, which is the best selling point, it is one of the best options.

However, there are other reasons which make it an excellent product.

The Pypes SJJ21R is very easy to install, and the most difficult part you will face when installing this unit will likely be removing the old exhaust system. Once you've done that, the rest of the job will be smooth and easy.

Even if you have no experience installing parts on a Jeep, you can do it in an hour at most without calling any mechanics or anything else.

Another thing that I really appreciate about this product is the depth of its sound. While it's certainly not the deepest sound it offers, it offers one of the loudest sounds on the market.

No matter how fast you are going, you will always be able to easily recognize the increased sound you get with this thing.

So, you better take your car out quietly after you install this system or you'll wake up the whole neighborhood!" .

The product also improves the performance of your Jeep, you may not notice an increase in mileage when driving around town, but you will definitely get a better experience on long trips or on the highway.

As a whole, this is an amazing all-rounder that offers a great sound and high clarity, making it perfect for your adventure trips.

Pros

One of the loudest exhaust systems available

Quick installation, no additional tools required

High road clearance

Significant increase in mileage

Cons

Can be a little too loud for some people

Looks are not the best

View Latest Price Bottom Line

This product from Pypes is one of the loudest I've ever seen. Has amazing clearance and is great for the rough driver who likes attention, however, you certainly won't get the best look.

10. ECOTRIC Matte Black Dual Exhaust Muffler

Last but certainly not least, this amazing Cat-Back exhaust system from ECOTRIC is as good as, if not better than, the previous products we discussed. Let's see how.

First off, this is one of the most durable build qualities I have ever seen. The beating steel is very heavy and no matter how rough you treat the bodywork, it won't wear out quickly.

ECOTRIC Matte Dual Bayonet Exhaust Muffler

In addition, the product comes in fully welded form, which makes it easy to install on a Jeep.

Now that we are talking about the installation, you would not believe how easy it is to follow it. The manual that comes with it is too good to be true.

The instructions are very clear and I didn't encounter any ambiguity. You don't need to use any additional tools as there is no soldering or cutting required.

Now to the sound and look, well it has it all and if you are a person who likes to brag, this could be a good choice for you.

With a flashy body and throaty sound, you'll get all the attention you need no matter where you pass.

However, there is one small issue in terms of vibration that I face, and since I am very sensitive to this issue, I have a hard time ignoring it. This is the only reason I wouldn't make it my next choice if I had to. However, if that doesn't bother you, then there is no problem and I see no reason not to go with this product.

Pros

Great aggressive sound; very loud

Very fancy looking

Quick to install: no welding or cutting required

Cons

Has some noticeable vibration

Not the best build quality

View Latest Price Bottom Line

The Ecotric muffler is one of a kind, and it offers you a great combination of elegant looks and plenty of sound. However, you will have to make some trade-offs in terms of durability.

Things to consider when buying a Jeep JK exhaust system

Before you lock in your choice, there are some points that you should never forget to consider first if you want the best product for you. Make sure you go through all of these and access your needs based on them.

Performance

There is no doubt that improving the performance of your vehicle is one of the most important reasons why people choose to buy an exhaust system for their Jeeps.

While stock systems aren't bad, they aren't great when it comes to bringing a vehicle up to its true capabilities.

Choosing a good exhaust system will not only increase your Jeep's mileage, but it will also have a big impact on its acceleration and horsepower.

So make sure you put enough pressure in this area and don't choose something that makes your Jeep look like it used to.

Sound

The sound of the exhaust system is another major aspect that you need to check thoroughly before deciding to buy it. While it is common to go for the loudest sound, sometimes it is best to look beyond just the loudness and look at other aspects such as depth.

In addition, the sound of the exhaust system can become a nuisance if it exceeds a certain threshold, making it difficult to drive unless you are driving at high speeds on the highway.

Therefore, make sure you choose carefully after doing enough research.

Road Clearance

I've come across many models that are great all-rounders with nothing to lose except good ground clearance.

Now, people don't really notice this at first, but then it becomes one of the biggest problems because you can't go off-road, even a little, and doing so will only cause your expensive exhaust system to wear out quickly.

As you know, it's no fun to drive a Jeep if you can't drive it without any worries. So, make sure the exhaust system is hooked up high enough.

Durability

Finally, I want to talk about durability and construction. I highly recommend that you don't compromise on this, even if it's not a good tradeoff. For the first year or so, durability doesn't seem to be an issue.

However, after that, the materials used in the construction quickly start to show their age, which is a big deal because exhaust systems are not really that cheap.
