Gibson 07-11 Jeep Wrangler JK Rubicon 3.8L 1-1/2in 16 Gauge Performance Header - Stainless

Starting with the 3/8 inch thick, laser-cut port flanges, these Gibson headers are built solid to prevent warping and leaks. They're made from 16-gauge 409L stainless steel tubing, which is a well-built material that holds up well to the elements, especially important for a Jeep that sees street and off-road use. These headers are designed as a direct replacement for your factory exhaust manifolds, meaning no welding is needed for installation. They use OEM-style connections and the stock crossover pipe, making the installation process straightforward.

The primary goal here is to help your Jeep's 3.8L engine breathe better, especially at the low and mid-range RPMs you use most often for highway cruising and general driving. This improved airflow can lead to more usable horsepower and torque, and Gibson's dyno-tuning process aims to optimize that gain. They're also street legal in all 50 states, meeting EPA and CARB requirements, so you can be confident they'll pass emissions. Plus, they're designed to work with both lowered and raised vehicles, and Gibson backs them with a lifetime limited warranty.
