These JBA headers take full advantage of the redesigned chassis and engine of the 2005 Ford Mustang. 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 FireconeŽ merge device for enhanced scavenging of exhaust gasses. These headers fit perfectly inside the frame with no loss in ground clearance.
Direct replacement of the stock exhaust manifolds, header bolts up to the existing stock Y-Pipe/Crossover pipe. Installation requires modification to exhaust system. Takes between 3 And 6 hours depending on application. All hardware, gaskets, and instructions included.
