PLM Private Label Mfg Power Driven K-Series hood exit race header (4-1 Megaphone) features a true 4-1 merge collector with megaphone, to create equal exhaust flow.

A megaphone is added after the merge collector, 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 all K-Series engine swaps.
