Briefly below, I’ve reviewed all the models that have been mentioned above in the comparison table. As a summarizing note, I’ve also highlighted a few pros and cons that can better assist you in making the right call for yourself.

Without further ado, here are the 10 Picks of the best jeep jk exhaust systems!

1. MagnaFlow 15160 Stainless Steel Performance Exhaust System Kit

MagnaFlow 15160 Stainless Steel review
MagnaFlow 15160 Stainless Steel

I’d like to start this review with my premium choice, the MagnaFlow 15160 Stainless Steel Performance Exhaust System Kit. There are many features of this model that I like. Here’s what you should look forward to!

Firstly, the MagnaFlow is pretty durable and sturdy. Owing to its stainless steel construction, I really like the fact that this model can take a hit and still be as functional as it’s set out to be.

On top of that, the MagnaFlow is also pretty easy to install. The only thing that I required were a pry bar, a 15mm deep well socket, ratchet, torque wrench, and a WD-40. Compared to most models, this was a walk in the park.

The best thing about the MagnaFlow that I praise and appreciate is its CNC precision robotic manufacturing. This means that I’ll get a perfect fit and won’t have to worry about factory faults or other types of settings that make installation or performance difficult.

As far as downsides are concerned, there are a few things that I’d want you to keep in mind. Lately, there have been some units that are coming with manufacture defaults.

If you find one in your model, I’d suggest that you contact the manufacturer or supplier ASAP.

Furthermore, the MagnaFlow hangs a little too low. So if you’re into rock crawling or similar activities, you’d better be careful!

Pros and highlights
  • Sounds get higher with colder air
  • The model is easy to install
  • Has a very snug and precise fitment
  • CNC precision robot manufacturing
Cons and potential flaws
  • Hangs lower than other models
  • Some units come with factory misalignments

View Features on Amazon

Bottom-line
The MagnaFlow 15160 Stainless Steel Performance Exhaust System Kit is a pretty good kit to consider, and I seriously recommend it to all types of users out there!

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

Gibson Performance 17303-B Dual Split Exhaust System review
Gibson Performance 17303-B Dual Split Exhaust System

Next up, we have the Gibson Performance 17303-B Cat-Back Dual Split Exhaust System. The Gibson is my follow-up pick. Here’s what you should anticipate!

The Gibson comes packed with a well-detailed instruction manual that helped me through each and every process. Before this model, I was told that my jeep would lose the low-end torque with this exhaust.

However, I found that the manual addressed the exact issue and advised that I should unhook the negative battery cable for at least 30 minutes when installing (take notes, guys!).

The sound that this model makes is also quite resonating and makes the overall experience better. When you drive by, people will notice.

As far as performance is concerned, the Gibson didn’t really have any effect on the acceleration – it was moderate, at best. However, once I’m on the open road, I noticed that it opened up the engine a bit, and that’s when it hit me how good this model actually is.

Nonetheless, there are a few things that I feel should be addressed before you go ahead with the Gibson. Firstly, the model is a little compact, with a short distance between the tailpipes. As far as aesthetics are concerned, it’s not flattering.

Secondly, the pipes hang down a little too low. So if you’re going off-road, you’ll have to be a little bit careful.

Pros and highlights
  • Installation requires no cutting or welding
  • Has a resonating growl sound at take-off
  • Increases the gas mileage by a little margin
  • Comes with a detailed and elaborative instruction manual
Cons and potential flaws
  • The tailpipe distance is too short
  • The sound isn’t noticeable at higher speeds

View Features on Amazon

Bottom-line
If you don’t have any issue with the cons mentioned above, then the Gibson Performance is a model you should definitely go for!

3. aFe (49-08046) Scorpion exhaust system

aFe (49-08046) Scorpion exhaust system

If you’re looking for something that gives your jeep extra clearance during extreme angle climbs or descent, then the aFe (49-08046) Scorpion is the best pick for you. Here’s what I like about this model!

The construction of the Scorpion is pretty reliable since it features an anti-corrosion protective coating. This makes it easier for me to keep my exhaust system clean, and also makes the maintenance quite easy as well.

The functionality of the Scorpion is also something that warrants a positive review, especially because it has good presentation value and fits perfectly on my jeep.

On top of that, the model also has a good rumble when down-shifting. All in all, this makes the Scorpion a pretty interesting perspective, and arguably one of the best models of 2020.

However, there are a few things that need to be mentioned before going further.

I found the aFe (49-08046) Scorpion to be a little louder than anticipated and has more drones than usual. Normally, this wouldn’t be an issue. But if you’re using your jeep daily, then this can get pretty overwhelming.

The stock muffler was also a pain to remove from the rubber clamps. For that, I think it’s best to spray some grease and put your muscles to good use!

Pros and highlights
  • Has no droning at highway speeds
  • The tone at idle or dormant state is pretty nice
  • Great rumble when down-shifting
  • Has great presentation and overall aesthetics
Cons and potential flaws
  • Stock mufflers are difficult to remove
  • The sound is very loud in the initial stages

View Features on Amazon

Bottom-line
The aFe (49-08046) Scorpion is a pretty good model to consider. If you don’t mind the cons above, I think you should give it a shot!

4. Pacesetter 324082 Direct Fit Catalytic Converter

Pacesetter 324082 Direct Fit Catalytic review
Pacesetter 324082 Direct Fit Catalytic Converter

The Pacesetter 324082 Direct Fit Catalytic Converter is a low-maintenance model best suited for all-around.

The best thing about this model is that even though it is a lightweight addition to your jeep, it’ll increase the overall efficiency quite easily. This is because of its low restriction tubular design.

The construction is pretty durable as well. Made from stainless steel, the Pacesetter is a pretty good mount for the heat shield.

On top of this, the installation of the Pacesetter was also quite easy to keep up. There wasn’t anything particular or unique required to the process – just make sure that you go through the manual once, and you’ll be good for it!
However, there are a few things that are important, which I want you to consider.

Most important of all, the Pacesetter 324082 Direct Fit Catalytic Converter isn’t geared for heavy-duty work. If you’re planning to seriously upgrade your jeep, then I’m afraid this model isn’t the best pick.

On the other hand, however, if you’re looking for a quick fix and want to get your jeep out as soon as possible, then the Pacesetter might help you with that.

Pros and highlights
  • The model is lightweight and easy to store
  • The installation is pretty easy to put up with
  • Has a durable stainless steel frame
  • Conveniently increases the overall efficiency of your jeep
Cons and potential flaws
  • Not suitable for heavy-duty operation

View Features on Amazon

Bottom-line
If you’re looking for a simple model to work, then the Pacesetter 324082 Direct Fit Catalytic Converter will definitely deliver. However, to be fair, there are many other better models out there that you should look into for excellent performance!

5. DynoMax 39528 Stainless Steel Exhaust System

DynoMax 39528 Stainless Steel Exhaust System review
DynoMax 39528 Stainless Steel Exhaust System

The DynoMax 39528 Stainless Steel Exhaust System is a stylish feature that is both functional and good-looking. Here’s what I like about this model!

First things first, let’s address the basics. The DynoMax was an easy install and didn’t really require any professional help, for that matter. All I needed was a spreader tool to help me with the rubber hangers. Other than that, everything was pretty basic.

Once done with that, you also might like the overall sound the DynoMax produces as well. A deep growl, it’s exactly what you should anticipate from a jeep that’s been modified well.

At idle, it has a mellow rumble to it, which isn’t too overwhelming. Overall, the sound factor of this model is quite reliable and trustworthy.

As far as the construction is concerned, the DynoMax is manufactured from stainless steel. It doesn’t really come in different colors, but I don’t think that should be bothersome. Durability and resilience are what’s important, and I found them both here.

There are, however, a few downsides that I feel should be addressed before we go ahead with this model.

I noticed that the sounds almost disappear when the jeep was in higher gears. On top of that, the driver side outlet also hangs a little lower than the passenger side outlet.

It can get a little annoying at times, but I’ve learned to ignore it. Other than that, the DynoMax 39528 Stainless Steel Exhaust System is as good as it gets!

Pros and highlights
  • No droning at higher speed or higher gears
  • Has a mellow sound during cruising
  • Complements the overall aesthetics of the jeep
  • Has an easy fitting installment which requires minimal tools
Cons and potential flaws
  • Driver side outlet hangs lower than passenger side outlet
  • Very tough to get the tips on

Bottom-line
The DynoMax 39528 Stainless Steel Exhaust System is a pretty good pick, and I recommend it for all types of users out there!

Catalytic Converter for 2007-2009 review
Catalytic Converter for 2007-2009 Jeep Wrangler

The Catalytic Converter for 2007-2009 Jeep Wrangler is a direct-fit high flow catalytic converter that is best built for professional use. This model has many great features, such as heavy construction, easy installation, and maximum durability!

The best thing, out of the features mentioned above, is its heavy-duty stainless steel outer shell. Engineering for maximum durability, I can really rely on this model to pull through on tough and demanding jobs.

I also found the installation to be a breeze. The standard OE specification flanges are suitable for easy setup and don’t really require any particular type of modification.

However, it would help immensely if you kept the instruction manual nearby. I’ve always found it to contain relevant bits that help me out immensely in the long run!

Before we go ahead with the Catalytic Converter for 2007-2009 Jeep Wrangler, there is one thing that I’d want you to keep in mind.

You might find it difficult to install it, opposite to what I’ve mentioned above. Don’t worry about that; it just means that there is an issue with the fitting, and you can look into alternatives.

Don’t let that disappoint you – there are several other models that are best built for reliable use. Keep on reading and check them out!

7. ETL Performance Products

ETL Performance Products review
ETL Performance Products

The ETL Performance Products is an all-black kit that can be a pretty stylish addition to your Jeep Wrangler JK. Here’s what I like about this model!

First things first, the ETL Performance Products has helped me immensely improve the horsepower of my vehicle. On top of that, it also increased the exhaust flow. Together, these two have drastically improved my jeep performance, which is why I like this model.

On top of its excellent functionality, the ETL Performance Products also has easy installation and doesn’t really require any extra work. It’s a bolt-on method that can be easily followed by all types of users out there, even beginners.

There are, nonetheless, a few things that you need to keep in mind!

Due to the design of the model, the exhaust tends to sit slightly crooked. Though this doesn’t really have any effect on the functionality, it’s still a bad sight.

Furthermore, the exhaust tips included in the package aren’t that large but have a poor retaining bracket. A bit counterintuitive, it makes things a little inconvenient. For best performance, I’d recommend leaving them off.

Other than that, the ETL Performance Products is a pretty decent model to consider, and I think it’ll be a good fit for you if you don’t have any issues fitting!

Pros and highlights
  • This muffler is awfully easy to install and look after
  • Increases the pick up off the line
  • Will increase the horsepower of your jeep wrangler
  • It Will help immensely with the mileage of your vehicle
Cons and potential flaws

VXAR Exhaust Tip review
VXAR Exhaust Tip

If you’re looking for the best exhaust tip available in 2021, then the VXAR Exhaust Tip is one model that you should definitely consider. Here’s what I like about it!

First things first, this model is manufactured from high quality 304 stainless steel. On top of that, it has a repeated exhaust polish finish with wrapping that ensures that the frame stays anti-corrosion and rust-resistant.

Another great thing about the VXAR Exhaust Tip is that it is awfully easy to install. Unlike the other mentions on this list, this model is just one small component. That’s why it’s pretty easy to handle and get the hang of.

Once you do get the hang of it, you’ll how it increases the overall performance of your vehicle, especially the horsepower. Down the road, that’ll give you better mileage and reduce droning at higher gears. On top of that, it’s also environmentally friendly.

As far as downsides are concerned, there isn’t anything major or super important that I feel should be mentioned.
Just make sure that you pay attention to the installation process, and keep the model clean. The VXAR Exhaust Tip is arguably one of the best exhaust tips on the market, and it doesn’t get any better than this!

9. Dynomax 39510 Axle-Back System

Dynomax 39510 Axle-Back System review
Dynomax 39510 Axle-Back System

Next up, we have the Dynomax 39510 Axle-Back System. Solid, functional, and effective, here’s why I think you should choose this model!

The Dynomax 39510 Axle-Back System utilizes fiberglass matting technology, which allows the frame to absorb any type of unwanted vibrations. Not only does this ensure that there isn’t any excessive noise, it tunes to the mellow tone to a more standard level.

Another great feature that the DynoMax has introduced is the large internal flow tube. That allows the kit to have an improved exhaust flow and reduces any type of backpressure.

As far as installation is concerned, I didn’t find the process difficult or challenging. However, to make the most of it, I suggest that you refer to the manual to help you out. If that doesn’t suffice, there are several online resources on YouTube that can help you out.

The only main downside to the Dynomax 39510 Axle-Back System is that the drone can get a little overwhelming if you’re got a hardtop on. This, I’ve noticed, gets worse as time goes on.

Overall, the Dynomax 39510 Axle-Back System is a good model but isn’t as durable and reliable as others. So my general recommendation would be that you look out for something else if you’re planning to get something for the long haul.

However, if you’re looking for a quick fix, then this model is definitely up for grabs.

Pros and highlights
  • The large internal flow tubes reduce the backpressure
  • Unparalleled fiberglass matting tech absorbs interior resonance
  • Patented flow design eliminates all type of turbulence
  • Increases the mileage of the vehicle
Cons and potential flaws
  • Isn’t durable or sturdy enough for the long run
  • Drone noise is too much with a hardtop

View Features on Amazon

Bottom-line
I recommend the Dynomax 39510 Axle-Back System to everyone. However, there are other more reliable models to consider if you’re looking for something long-term.

10. Flowmaster 817674 American Thunder 409S Single Rear Exit Cat-Back System

Flowmaster 817674 American Thunder 409S review
Flowmaster 817674 American Thunder 409S Single Rear Exit System

Last but not least, we have the Flowmaster 817674. One of the best in 2022, here’s what you should anticipate with this model!

First, let’s go over the frame. Manufactured from stainless steel, this model is durable and reliable for the long haul. Its solid exterior can take a hit, which reduces the possibility of decreased performance if you’re going off-road.

A unique thing that I found about the Flowmaster 817674 is that it utilized a patented laminar flow technology. I like this bit because it means that the airflow is perfectly smooth and geared towards optimal performance.

The installation bit wasn’t that challenging to keep up with, honestly. It’s a good idea to get help from online resources or a professional since the manual isn’t that good.

There are a few downsides that I think you should be wary of. However, don’t look at them that way. I found them to be a temporary inconvenience, and they sorted out themselves down the road.

Firstly, the sound that was produced initially was a little too loud and gave me a headache. However, after a short while, that whole thing went away, and the performance was as good as ever.

Overall, I think the Flowmaster 817674 is a pretty good pick. I think everyone should give this model a shot!

Pros and highlights
  • Has a good and tight fit
  • Provides maximum off-road clearance
  • Features patented laminar flow technology which reduces any restriction of airflow
  • Has a durable stainless steel construction for heavy-duty use
Cons and potential flaws
  • The instruction manual isn’t that good
  • Initially produces a very strong noise during driving

View Features on Amazon

Bottom-line
I recommend the Flowmaster 817674 to all types of users out there in search for something reliable and worth it!

Things to consider when buying a jeep jk exhaust system

When choosing the best Jeep JK exhaust system for your vehicle, there are a few things you’ll need to keep in mind.

Material

The first thing that I want you to watch out for is the material. Since this part of the vehicle is always under stress and heat, it’s a good idea to go for stainless steel.

Not only would it make the whole system resilient and strong, but it will also ensure that your model doesn’t cave in to pressure differences or prolonged exposure to heat.

Make sure that the manufacturer or vendor is reputable and has a clean history because counterfeit products claim to be made of stainless steel but are actually of lower quality.

Not only can they ruin the experience, but they can also make the whole thing dangerous.

Fitment

The next thing you’ll need to keep in mind is fitment.

Some models are a bolt-on fit and don’t really require any particular adjustment. However, there are other that only cater to particular vehicle types.

When choosing a model, make sure that you examine your vehicle’s catalytic converter and note the dimensions.

Installation procedure

Lastly, pay attention to the installation process highlighted.

If you’re planning to do everything yourself, it’s a good idea to choose a model that is easy to install and doesn’t require any professional help or intervention.

However, if you’re a professional, or have the experience, or plan to get the fit done professionally, then you have the liberty to choose whatever you want. But keep the above two points in mind!
