Byhalia glad you got the bolt. I have zero trust in the postal system.
The high pipe may not even be built for the market, depending on what Lang Hindle projects as potential sales. So price isn't known...but I guess it would be about the same as his present 4-2-1 Busa System (you're in the States so ask your dealer).
He hasn't decided how high to take it and will do that after fitting the current prototype to my bike and dynoing it pre-post. Racers like high pipes to keep their cans off the ground, but there's no need for that on a Busa on the track, so it would really just be a niche cosmetic thing that also saves weight and increases power. It's for a serious trick bits junky like JeffW.
I don't even know if I'll put it on my bike. Hindle will give me some consideration for letting him use my bike, but I could just take it out in Dyno runs. Hindle's shop is less than a minute from my home.
