I have a prototype 2.7L V6 header for the Tiburon that I will let go for $250 shipped. I was trying to develop this part for Kia applications with a far lower retail than anybody else who offers a similar product (Ark Racing sells them for $899). I didn't get any interest, but maybe I was asking in the wrong places... Regardless, I am willing to take a loss on this just to help somebody out. It's on the KFX homepage for purchase.
