H-Series hood exit race header (4-1 Megaphone) features a true 4-1 Megaphone merge to create equal exhaust flow. A megaphone is added next, to release pressure and increase the speed of the exiting exhaust gases. A small reverse cone is placed at the very end to provide a tiny bit of wanted back pressure. This header delivers the best peak horsepower gains while utilizing a 2 piece design. This is ideal for all forms of competition; Autocross, Drag racing and road racing. Recommended for 1.8-2.2L engine displacements
