Those are super cool! I'd love to have them avaible for the Mopar world.
Here is a similar flange Burns Stainless built for a set of headers I did for a Jon Kasse Boss 9. Not sure if you can copy any ideas over to yours.
Definatley very cool to have the tube socket in, and be blended back to the rectangle shape.
Nice looking pieces. What size primary tube was that? Probably easier to do when working with under 2 1/4" primary. The full transition looks nice, but probably isn't the lightweight way to go. Looks great none the less.
