I like it. Large radius bends, smooth collection, steps up in overall size after each collection. For an UEL header, there isn't much not to like. I'm personally still partial to the EL design cause I'm an engineering nerd, but that's just me. I might suggest trying to run a small variety of pipe sizing on the dyno and see what works best. There will likely be some sensitivity to each step, and there might be interesting results if you step up or down on size for any of the pipes. It depends how much R&D will be invested. You might have 3-4 finished prototypes and a hours on the dyno to see what combination provides what gains/losses.
