Hi Ed, Burns Stainless has a fitting that will work, but it isn't really ideal either. I could probably get a muffler shop to expand the end of my pipe, but the heavy, mild steel flange bothered me too. I went ahead and ordered some 1/4" 321 to make a new flange, but this isn't a perfect solution either. Now, I'll have a 2.125" port on the rotor housing going into a 1.68" ID tube. Since the port on the housing tapers out to that size, I don't think it will be a huge problem, but I may look into extending the exhaust tube slightly through the flange, and shaping the end so that it closely fits the walls of the ports. Until I look at it more closely, I won't know just how worthwhile this would be.
