Buyer’s Guide

The fact is that no matter the number of options presented in the article, you need a useful guide at hand as to what to pay attention to when choosing the right exhaust system for yourself. There is a number of features to be aware of and to differentiate between. That is why I’m going to point out all of them in this Buyer’s Guide.

Pay attention to the material

First things first – not all the systems are made of the same steel type. There are three main kinds of steel used in exhaust systems, they are:

409 stainless steel – it is a highly popular steel type use din exhaust systems manufacturing. It is quite durable and pretty resistant to corrosion. Usually, the system made of such steel will last you up to 8 years.

304 stainless steel – this is a more durable and long-lasting steel type. However, as you may guess, systems made of this steel type usually cost more.

Aluminized steel – a pipe made of mild steel requires rust-protection, and that is when sprayed aluminum coating comes in more than handy.

Consider the Sound

When you are looking for an exhaust system, the sound it makes may not bother you at all. However, some drivers prefer louder systems to milder-sounding ones, all due to the fact that a louder sound may emphasize the power of the Jeep’s engine. It is optional to compare the sounds of various exhaust systems’ providers, but I think it to be useful information to be brought up to a beginner.

Cat-Back and Axel-Back Systems

It is essential that you differentiate between cat-backs and axal-backs when it comes to choosing a suitable exhaust system.

The truth is that axel-back systems are a lot more affordable and easier to install. This type of exhaust system will improve the quality of the sound that your Jeep produces, but that is about it. It will add up to the general outlook, too, but it will not influence the Jeep’s performance much.

axle-back exhaust system

Cat-back exhaust systems are pricier for a reason. The fact is that when you choose to install this system type in your Jeep, you may as well change all the components of it. Besides, the system is designed in such a way that it will add up to both the general appearance of the Jeep as well as to its performance.

cat-back exhaust system

Considering the Design

It is true that not all drivers pay a lot of attention to this point since all they are interested in is the sound and the performance of the Jeep with a new exhaust system installed. However, if you want your car to look matching with the new system, I suggest you pay a little more attention to the designs available on the market.

Clearance

When it comes to clearance, you need to think about the roads you are going to drive your Jeep on. If you are all about unpredictable and tough off-roads, I suggest you take a system with higher ground clearance so that you do not damage it while ascending or descending an unpredictable off-road.

Price

Lastly, every driver should come up with a budget he or she is willing to spend on an exhaust system. There are various prices offered on the market, and not all the systems that come a little cheaper are necessarily worse and vice versa.

FAQ

How long does a stainless steel exhaust last?

There are different types of stainless steel that exhaust systems are made of. If we take 409 stainless steel, for instance, it will last approximately 8 years, no matter the climate or weather conditions. However, 304 stainless steel is considered to be even more lasting, besides it can withstand saltwater corrosion too.

How long will an aluminized exhaust last?

With the aluminized exhaust system, things get a little different since the aluminum coat can’t save the system and keep it non-rusted forever. If you live somewhere with a moderate climate, then such a system will last you up to 5 years, in a dry climate, the system will serve you as long as 8 years if not more.

Is a true dual exhaust better?

You should think about a dual exhaust as of two ways that your engine is getting fresh air from. The more there is air to ‘breathe,’ the more powerful your Jeep will become. However, you should not mix a dual exhaust with dual exhaust tips. The tips will only add up to the design but not the engine’s power.

Do aftermarket exhausts improve MPG?

The fact is that an aftermarket exhaust system can improve your engine’s efficiency by up to 10%. That means that you can either waste it on horsepower increase or you can choose to spend it on fuel economy.

Conclusion

Not everyone knows, but the better your exhaust system is, the better your engine can breathe. When there is enough cool air sent to the engine, everything starting with horsepower and ending with fuel economy can be increased. There are many exhaust systems available on the market these days, and most of them are different, and there is a reason for that. Depending upon your preferences and needs, you can choose the best fitting one, and hopefully, my review will guide you in the right direction toward the best exhaust system for you, Jeep Wrangler!
