Every manifold Professional Products makes is 100% pressure tested. That means the water jackets are pressure tested for leaks, the plenum and port runners are tested for leaks, and the exhaust gas crossover (when utilized) is tested for leaks. This is an extremely time consuming process which is why it is not used by other manifold manufacturers. Do the installation once and do it right.

The Professional Products Power+Plus TYPHOON manifold for injected Mustangs is a breakthrough in styling and performance. Available in satin finish at a price that is hard to believe, this manifold is suitable for high performance street use, bracket racing, nitrous, or supercharged applications. Use the Professional Products 70mm Throttle Body for optimum performance. On 1994-95 applications, use their Elbow Adapter #54150 or 54151 and Strut Tower Brace #M-20201-A51 from Ford Racing or #5225 from Edelbrock for proper clearance. 1994-95 applications also require our #54152 EGR Adapter.
