These new headers take full advantage of the redesigned chassis and new engine. The trick "D" port aluminum heads on the 4.6L 3v can breathe easier through JBA's 1.625" mandrel-bent stainless steel primaries freeing up massive amounts of horsepower and torque. JBA's one-piece .375" CNC laser-cut flanges make a tight and durable seal for trouble-free performance. The pipes terminate in a 9" long collector that houses JBA's patented Firecone® merge device for enhanced scavenging of exhaust gasses. These headers fit perfectly inside the frame with no loss in ground clearance. Advantages: Increased horsepower and torque throughout RPM. Improved throttle response. Ceramic coating reduces under-hood temperature. Improved fuel economy. Improved engine compartment aesthetics. For off-road use only.
