Kooks 6.4L HEMI Exhaust Performance Headers; Wrangler JK

Very Minor Trimming Required on the Motor Mounts! When using an AEV HEMI Conversion Kit to install a 6.4L in your 2012+ JK or JKU, you must use headers from a 5.7L. These headers have smaller inlet holes than the block of the 6.4L. This hinders the full performance potential of the 6.4L, by reducing exhaust airflow. RubiTrux collaborated with Kooks Headers and Exhaust to custom design a set of headers specifically for 2012+ 6.4L HEMI swapped JK and JKU Wranglers equipped with AEV's cat-back exhaust system. These long tube headers not only eliminate any airflow restriction, but they also give you beneficial power gains with even bigger performance increases seen from dyno tuning! Made in the USA!
