ProSport headers are a work of art. They are fully constructed out of T304 stainless steel, including the flanges. This set includes the pictured uppipe which uses the ProSport exclusive 3 bolt flange design between the manifold and uppipe providing a stable connection without air leaks. With a jaw dropping 45mm inner pipe diameter you can be sure your spent exhaust will exit in a hurry. Dyno tested this header and uppipe added 13 feet per pound and 11 horsepower to the wheels.
