just looked on summits website. ive bought several sets of summits truck headers. they are 109 bucks. they work well.only downside is for a performance application the tubes are only 1.5 inches. headman makes a set too for 159 bucks from summit. i suggest some "good" flange gaskets and dont overtighten bolts. as you will bend the flange which can cause exhaust leaks.this condition can happen with any header.
