These from Andrew(walms) http://kawi2strokes.com/forum/viewtopic.php?f=25&t=397&hilit=kit, but you will need to have a skilled welder put them together. They have a modern power curve, not just top-end like the old school pipes. But, since you are planning to have reeds, you might also consider a set of Jim's pipes which are repops of the tried and true old school Dencos http://www.lakeserv.net/kaw/chambers/. I as well as MANY others here have purchased and are running his FINELY-crafted works of art. And these also come fully welded, bolt-and-go!
