Scorpion don't sell linkpipes on thier own purely to stop exactly what you have done, they sell a can to fit a bike, if your can wont fit wih thier linkpipe then they dont want to be harrassed coz essentially it not thier problem.
Even dealers struggle to get seperate parts.
Try ART, they used to sell them seperately, if not mark hill at MHP can make you one
