Things to Consider Before Buying Best Exhaust System For Jeep Wrangler JK

While there are many options to choose from, there are still a lot of points to deliberate before changing your original exhaust system.

For car enthusiasts and beginners, industrial exhaust systems are worthy and considerable vehicle enhancements.

They are eye-catching and sound good too. Many aftermarket systems ready to buy nowadays are available for easy installation purposes.

It’s essential to keep in mind, though that not all of these systems are created equally.

Here are the top ten things to take into account before considering the exchange of your Jeep Wrangler’s stock exhaust system.

01. Material

It should be the top priority, and your aim is to find at least something that has a similar build and equipment as your stock exhaust.

Remember that a highly durable material will last you a long time, and it will also be more compatible to work well with your Jeep.

Always consider the content of the material, what kind of steel was used, or if it’s a lasting one.

02. Noise

Another critical factor for consideration is the sound. While some people don’t really mind this point, others are more conscious and want only the best.

Always check the sound quality of the brand you choose to buy, whether it gives off a pleasant tone, both internal and external.

Check product reviews as some brands fail to deliver accurately, as the product describes.

03. Shape and Size

Check out and look up your exhausts’ dimensions and shape. This way, you are ensured that the one you buy will still fit your vehicle’s exhaust size.

Buying something that won’t fit your vehicle’s dimension is a waste of money and time.

04. Resistance to heat

Keep in mind that your engine evicts heat through the exhaust system. This means that the aftermarket exhaust of your choosing should be able to withstand extremely high temperatures.

Don’t forget to check the heat-resistance capabilities of the new system you choose to buy to ensure the top performance of your vehicle.

05. Coating

It is directly related to the 4th point as the coating quality of your new exhaust system will determine its durability.

There are several coating types available, so utilize the internet, ask around people you know, or research on each one before completing a purchase.

You would want something resistant to high temperatures, as well.

06. Installation

Before buying any aftermarket exhaust product, be sure to check your Jeep’s specific requirements thoroughly.

Consider if the tools for installation are available or not as you might have to shell out money for an additional purchase of these items.

Choose the one that provides all clamps and tools for easy fitting. You will save money on going to the shop as well if you can do it yourself.

07. Design

This is a subjective choice, but it is still recommended to choose something that will aesthetically please you to avoid feeling remorse after buying.

There is plenty that doesn’t only bring quality performance but also looks sleek and feels classy. Your exhausts’ design adds up to the view of your vehicle.

This adds up to the overall satisfaction of your purchase.

08. Muffler

It is for people who are very particular about the tone and sound the exhaust system makes. Generally, your muffler size will discern the loudness and intensity of your exhaust.

Keep in mind that bigger mufflers emit a much quieter and lesser sound and vice versa.

09. Fuel Consumption

Car enthusiasts, especially beginners, will be very eager to step on the gas more than usual to check or even strut off their new exhaust system.

Though it may not be very important, take time to consider this point too.

10. Don’t compromise

Settle for a system that will save you a few bucks as repairs will be more costly in case something goes wrong.

Never choose low-quality exhaust on your car; instead, try to find something more on par with the original one.

Frequently Asked Questions about Best Exhaust System For Jeep Wrangler JK

What is a vehicle’s exhaust system?

It’s one of the essential components of your vehicle and the one responsible for filtering out gas and fumes from the engine, which then releases this unto the tailpipe.

Technically, your exhaust system is your car’s respiratory system. A high-quality one will cost you some money, but it also increases your gas mileage, horsepower, and torque.

If you are considering replacing the stock exhaust of your car, understand the importance of this part first, then decide which one is the best replacement.

Are there different types of exhaust systems?

Yes, there are. Generally, three distinct exhaust systems are popular to use for Jeep Wrangler JK. They are as follows:

  1. Cat-back exhaust – this is one of the most installed exhaust systems to Jeep Wranglers. This system changes every pipework and adds a new muffler to substitute everything from the catalytic converter of your wrangler. It’s proven to have an overall better exhaust performance and is a very popular choice nowadays.
  2. Axle-back exhaust – this cost a little cheaper than the former exhaust and is installed on the rear section of your vehicle axle. This requires no modification or cutting of any of your factory settings, making it a viable choice for the easy installation process.
  3. Exhaust headers – These are usually paired with the cat-back system. It is a straightforward bolt-on accessory that can be installed to a vehicle for the purpose of improving the performance of the engine. Its primary responsibility is to push out exhaust gas from the exhaust system.

What is better cat-back or axle-back exhaust?

Although axle-back exhaust costs less than the cat-back, and it produces an overall better sound quality compared to the other systems, the cat-back exhaust system is considered the best by many.

It’s true that you have to pay more money for this, but you are also assured of its excellent benefits and more of the additional performance improvements.

Is a true dual exhaust better?

It definitely is. Having a dual exhaust means you can get rid of the used air (exhaust) faster, but it’s crucial to establish what a ‘true’ dual exhaust is.

Sometimes people automatically assume that two tailpipes are a dual exhaust. It isn’t. A true dual exhaust has two tailpipes and two mufflers.

With a true dual exhaust, your vehicle gets more horsepower and good mileage.

Does aftermarket exhaust add horsepower?

In a way, yes, it does. But it depends on what kind of vehicle you have the system you choose. Some aftermarket exhaust systems can add up to 50 horsepower as the highest, and two horsepower as the lowest.

So be careful in choosing your purchase or stock replacement. Make sure to do a thorough research of what the aftermarket system best works with your default system.

Does a stainless steel exhaust improve performance?

It definitely does. Performance is just one of the benefits of installing a stainless steel exhaust since it also improves quality and durability.

They are the standard options of many car enthusiasts and makers nowadays. Typically, stainless steel radically makes your car perform better as it makes the engine cool down faster.


The Jeep Wrangler JK has been around for a long time, so there are already many options available for everyone nowadays.

It is essential to know precisely how changing your stock exhaust system will improve your vehicle at the same time.

The performance, look, sound, among other critical deciding factors (as listed above), should be put into careful consideration.

Each product offers various benefits and some disadvantages as well. It’s important to weigh in your options before making any decision.
