Are they > off the shelf units? Yes, they are Peter. They are "ball" joints used by the aircraft exhaust folks. Not cheap -cost me around $50 each back 5 or so years ago, but they seem to last. The two halves of the ball are held together with three small bolts with a heavy spring that pushes the two halves together. So far the heat has not yet destroyed the temper of the springs, but I have adjusted them once since installation to make it tighter. . I've seen another cheaper (and perhaps better?) alternatives. See http://www.nickson.com/4_Products/FEConn%20Folder/flexexhaust.htm http://www.epiflex.com/newviewflex.htm I understand that JCWhitney stocks them in their catalog. Some have stainless steel pipes on the end and others have aluminized steel - so you need to check that out. I suspect that these are heavier than the aircraft ball joints but probably less expensive. I found my aircraft ball joints in AirCraft Spruce and Speciality catalog. Ed
