Does anyone know if there is a place to get a flex or wrap-around header and pipe combo that will work on a Saito 4 stroke engine? I'm putting together a Zen 1.20 for intro into pattern and a friend of mine has a Saito 1.20 or 1.50 (can't remember which) he might be willing to sell me for a great price. But I want to run the pipe with it.
