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.

Nicholas M. ★★★★★

The megaphone and reverse cone give it a sound I wasn't expecting, way deeper than the old setup. Fitment on the hood exit was tight but everything lined up without any trimming.

James ★★★★★

The 4-1 merge collector really changed the tone up top compared to my old setup. Fitment on the K-series was tight but everything lined up, and that megaphone out the hood sounds absolutely nasty at full tilt.

Sebastian ★★★★☆

Installed it on my K-series build and the megaphone section really opens up the exhaust note nicely. Fitment was pretty good overall, though one of the bolts was a tight squeeze to reach.
