Holley Performance Products is proud to announce additions to the Flowtech header line for both JK and XJ Jeeps with 6-cylinder engines! These headers are available in either a painted finish, or a durable satin ceramic coating for added longevity. All headers feature high flowing, mandrel-bent 1 5/8" primaries to provide consistent tubing diameters for smooth transitions and high flow, increasing exhaust velocity. This will help your Jeep make more horsepower and torque through the entire RPM-range! They also feature 3/8" flanges for a leak-free seal and maximum strength to ensure that your install is done right the first time. The collector flanges and oxygen sensor bungs are specific to each truck, ensuring an easy install that bolts right up to your factory exhaust!
