Looking at their work it looks like they should have a good idea based on engine specs ect to modify the design to gain much more power.

I don't think you could get more power than what you get from Supersprint's Stepped Headers, something around 25hp. The normal after market headers from Supersprint and AA give around 20hp. I'm expecting these to do the same except they'll have a lower resale value.
At $1,300, I'd rather get Supersprint or AA which are both $1,399 retail.
