Check Stahl for header kits.
I got my tubes and collectors from them and bought the W-9 flanges from SPD.
They sell theirs in varying stages of completion and make a nice part IMO.
As for the star , I liked Headers By Ed 's approach.
He heats the tubes where they transition into the collector and pulls the inside of the tubes in with a needle nose vise grip , so where the four tubes come together get the appearance of a cross. He claimed this was worth 5 h.p. on the dyno as I recall.



Ed has a good audio tape on header building.
