I bought this through another seller and have been extremely happy with them. They sound great, look fantastic, decrease drone, and offer a noticeable difference in seat of the pants performance. Get a new down pipe and delete the factory dent meant for emissions to compliment this header and 2.25 or 2.5 catback. If you really want a boost in performance, get a 62mm throttle body (also from BBK) 12 hole injectors, and 1.7 ratio aluminum rocker arms. That combo will do magic for the 4.0.
