When you push your JL to do off-road activities, you need to know that your machine can handle it. You need the exhaust gases to burn and be removed from the engine as quickly as possible to ensure the best performance overall. If these gases are not removed, you will find that the engine cannot perform at its best and your performance will suffer. A good header will ensure that your JL works the way you want it to and many individuals who install a new header find that their performance is dramatically improved. At Extreme Terrain, we carry 2018-2023 JL headers made from some of the top names in the business such as Rugged Ridge and AFE. Our headers come in a variety of styles and materials to include chrome, ceramic, and more. Whether you want a Y-pipe or long tubes, we offer them in our online shop.
