PLM Private Label Mfg. Power Driven K-Series hood exit race header, features a true 4-1 merge collector with megaphone and reverse cone, to create maximum 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. Recommended for all K-Series engine swaps.
