The Duster was already built when I bought it. I think that they're HOOKER headers. I'm not sure because there is not a tag on the left set that I'm used to seeing on other headers from HOOKER. It's possible that the tag popped off or was removed when the previous car they were in was wrecked. The welded sections on the left header were the result of the repair work they did after the accident. I tried doing a Google search for images to compare and these do look similar to the 5215 that they sell.
