Buying Guide: Things To Consider In An Exhaust System

Whether you are considering a change of exhaust system because the earlier one has died out or you simply wish to improve and upgrade your jeep profile, there are still some points to consider. While all the exhaust systems for jeep Wrangler mentioned above are good, the best will depend on your personal preferences.

#. Material

This is the most important thing to consider, and your priority should be to look for something that has a similar build and equipment as the previous factory exhaust. The highly durable material will last for a long time and will also be more compatible with your Jeep.

# Sound

The sound is an important aspect for which many jeep owners consider replacing the stock exhaust system, while there may be few others who don’t mind. Make sure you always check the sound quality of the brand to get a pleasant tone internal as well as external.

#. Design

While this is a subjective choice, we strongly suggest that you select something that will please you aesthetically and not make you regret your purchase decision. There are several options in our list of best exhaust systems that not only deliver quality performance but also appear sleek and classy.

#. Shape and size

If you order an aftermarket exhaust that’s bigger or too small in size than the factory part then this will result in a bad fit. We strongly suggest that you consider the dimensions and shape of your exhaust system so that you don’t waste your time and money.

#. Coating

How durable the exhaust system depends directly on the type of coating on the exterior. While there are different types of coatings available, we suggest that you refer to customer reviews and expert advice before choosing what is right for you.

#. Installation

Make it a point to check the aftermarket exhaust product and also inspect the specific requirements of your jeep thoroughly. You may want to consider if the tools for installation come with the package or you will need to spend extra to acquire those items separately.

#. Heat resistance

The job of an exhaust system is to help the engine turn out the heat produced. Hence, make sure that the aftermarket exhaust system you purchase is capable of withstanding the extreme temperatures. Always remember to check the heat-resistance capabilities of the new exhaust system before deciding to buy.

#. Muffler

This feature is particularly for those who are more concerned about the sound and deep tone produced by the exhaust system. In general, the muffler size decides the loudness as well as the intensity of your exhaust system. Also, you may want to keep in mind that a bigger muffler produces a quieter sound and vice versa.

#. Fuel Consumption

The jeep enthusiasts may want to keep a check on the fuel consumption before deciding on the new exhaust system. Although this is not a very important feature, nevertheless take some time to consider this aspect too.

#. Warranty

When choosing an exhaust system, we strongly suggest that you look for a system that is backed by the manufacturer’s warranty period. This should help you save some money in repair work, as repairs may turn out to be more expensive if something goes wrong. Try to find a system that is not low-quality then your existing exhaust system.

Axle-back exhausts Vs Cat-Back Exhausts Vs Exhaust Headers

jeep

If you are a beginner looking for a new exhaust system for your Jeep Wrangler, expect to feel confused with the different options available. Most people get confused between the Axle-back exhausts, Cat-Back Exhausts, and Exhaust Headers, so let’s take a closer look at them.

Axle-back exhausts

The Axle-back exhausts are some of the most affordable exhaust options and they are also cost-efficient. They are not only capable of producing the best sound quality but also enhance the appearance of your favorite vehicle. In the case of an axle-back exhaust system, only the end of your exhaust system is replaced hence they are comparatively easier to install.

Cat-Back Exhausts

Known as a step above the axle-back exhausts, this cat-back exhausts deliver a much better performance along with an aggressive sound note. This exhaust system is capable of replacing everything past the catalytic converter, including the resonator, muffler, and also some of the piping. It not only improves the performance of jeep on the road but also on the trail.

Exhaust headers

Although the exhaust headers are mostly paired with a cat-back exhaust system, they are also known to provide a lot of advantages when used on their own. They are known to have individual primaries for each cylinder of the engine that travels into one collector pipe. The headers also eliminate the backpressure by separating exhaust gases into separate and individual tubes.

Related Questions

Is a dual exhaust better

Yes, because when you have a dual exhaust system, this means you can get rid of the used air much faster. However, you must remember that having two tailpipes does not mean this is a true dual exhaust. They typically have two mufflers along with two tailpipes.

Can a stainless steel exhaust improve performance

Yes, when you install a stainless steel exhaust system, it can automatically improve the performance of the vehicle. It also increases the durability and overall quality of the ride. As stainless steel is capable of cooling down the engine much faster, it helps in making the engine perform better.

Can an aftermarket exhaust help in increasing horsepower

Yes, it can but this will also depend on the type of vehicle you have and the exhaust system that you choose. Some aftermarket exhaust systems are capable of adding up to 50 horsepower at the maximum and 2 hp at the minimum. So, always be careful about the choice your make.

 How long does an aftermarket exhaust system last

The typical life expectancy of a premium-quality aftermarket part is usually between 2 and 3 years, based on the driving habits. Some of the other factors that affect the system are manufacturer materials, condition of the components, and other environmental factors.

How often do you need to replace an exhaust system

The existing exhaust system does not need to be replaced until you seek a higher mileage or wish to add more years to the engine. Most vehicles having a stainless steel system will not require any exhaust work for about 8 to 10 years due to corrosion resistant feature.
