[VXCL]

the lx has an exhuast manifold and the ex has a cast iron 4-2-1 header (we only have one). thats what helps make the additional 15hp over the non vtec f22 accords. of course the vtec is responsible for the majority of the additional hp, but u will get a slight mid to high gain. maybe like 5hp peak. if u can get em cheap its worth it. especially if u already have a CAI and full cat-back exhuast.
