Touring Muffler position

Wow that "cat box" is restricted. I realize the cats are in the mufflers on the touring. I will make or get a bypass. Has anyone ever pulled out the " crimps" in the stock R3T header?

B) =Swingarm to R/H muffler

I make this as a direct replacement for the Touring and the Roadster Rich.

 
Yea, that would be good to Norm, can't hurt to have a couple of sets of figures.
PAUL all you need is a nice compct simple 3 to 1 slipon for the R3T not 2 big pontoons that kill power and offer a dual version for the ones that must have 2 pipes even though though it hurts the power output .
 
I'm interested in 3 into 1 with your header. I know I keep jumping back and forth back and forth between Carpenter's sidewinder and yours. It will still be awhile either way.
