Thanks Soren. I was actually thinking of the upswept trumpet style pipe which is about as short as the turnout pipe in the picture, but since its upswept, I'd have to extend the header pipe to mount it so it clears the sprocket cover on the right side and the shift linkage on the left side. Now that winter seems to have set in here in New England, there's nothing left to do except think of interesting new projects for the bike. This site provides lots of great ideas. Pat
