Wilbur: I agree with you. I've done a lot of engine/driveline/conversion jobs in my life and learned long ago that exhaust work is not my bag. But if Davidn wants to take it on, maybe he can do it and learn something at the same time. One thing I learned was that if you take it to an ordinary muffler shop, they will more than likely foul it up. You need someone or a shop that is experienced in custom exhaust jobs, and pay the $$$'s they want.
