I have a cone and maybe the cone coupler laying around , not sure what else , but I doubt I have a complete pipe anymore.
One more thing you might want to check out , the Tigershark 640 cone is longer and just slightly larger in diameter , it will still fit the stock 650 rubber coupler and would help that 650 pipe out a lot on a 750 , I know that you have some 640 stuff laying around there.
Most of the mods I see done on 650 pipes involve lengthening the cone or adding a section to it.
