Has anyone fitted one of the new big bore headers from Cycleworks onto their DR650? If so how did it go?

I emailed the seller for some more info and suggested dyno sheets to show how much and where the improvement was but got a fairly pointed reply back saying if I wanted dyno sheets to buy something american and that his butt dyno was proof enough and I should be happy with that, I found the reply quite arrogant actually.
