SLP long tube headers feature a polished ceramic coating to keep heat in exhaust velocity up and under-hood temperatures down.

These headers feature 4-into-1 CNC bent 1-3/4" primary tubes flowing into two 3" merge collectors with an integrated spike for increased power better scavenging and improved sound.
