How to Choose an Exhaust System for Jeep Wrangler JK

The first consideration about an exhaust system is detailed in how you use the vehicle. If the vehicle is used to drive to and from work, and around town, you want an exhaust system that meets all regulations and codes. Your system must be within the decibels regulated by your city ordinances.

If you drive off-road and do a lot of playing on old dirt paths, or new paths that you have created then the clearance of the exhaust system likely means more to you than the sound or decibels.

Before you pick a system think about how you will drive the Jeep the most, and what you want from your exhaust system.

Fuel Consumption

If you want your Jeep to get better fuel mileage then you want a free flowing exhaust system that does not have a lot of bends and crooks in the pipe. You want a simple system that directs the exhaust out of the pipes with minimal effort. If the exhaust system has to work hard to push the exhaust out then it is going to take fuel to help it work.

Some exhaust systems create fuel efficiency that gives people as many as 25 more miles per tank of gas. With the prices of fuel this could equal a lot of money saved.


If you are putting the system on an off-road toy then you want your system to sound as aggressive and as loud as it can. If you drive past homes with sleeping people, and through towns then you want overly aggressive sounds.

You have to determine where you will drive the most, and how you will drive your vehicle.

Mandrel Bent Pipes

When an exhaust system says it has mandrel bent pipes the tubing that makes up the exhaust pipe was bent by inserting a steel pipe in the tubing. The inserted pipe remains rigidly in place and pressure is applied to the tubing to cause it to bend around the rigid pipe.

The result is a bend that has no wrinkles or restrictions. It is also a bend that is strong and will not be subject to deterioration like a bend that is made and then joined to another pipe. The mandrel bent tubing is a solid piece that has not been cut, and no clamps or bolts have been used to join it back together.

Final Thoughts

Exhaust systems can make your vehicle sound tougher, and make it look tougher. An exhaust system can increase your horsepower and make your vehicle capable of pulling more or climbing steeper hills.

The right exhaust system saves money for you by allowing you to use less fuel. The right exhaust system customizes the look, sound, and performance to make your Jeep Wrangler a unique vehicle.

The only hiccup you may have with a new exhaust system is voiding your warranty from your manufacture. You should never change any exhaust system until you check your warranty and confirm that you are allowed to make the change.
