The harder you push your JK, the more gas and air it will burn and exhaust gases must be removed from the engine as quickly as possible to make room for clean air. One of the many modifications off-roading enthusiasts make is to put in headers. A good header will help your engine breathe by reducing unwanted levels of back pressure and letting gases flow more freely. Drivers report an increase in horsepower and torque soon after installing a new exhaust on their JK. Gas mileage and overall performance may also improve with the right headers. We offer a wide selection of replacement Jeep Wrangler partsand accessories, as well as exhaust components like cat-back systems and mid-pipes that are very popular JK performance items. Why would someone go through the trouble of replacing all those parts? Because performance is important to them! In order to push their Jeep Wrangler JK's to the limit, off-roading Wrangler owners often invest in aftermarket replacement parts. These specialty parts can improve horsepower, torque, gas mileage, and emissions.
