Hi Flanny. Just to get inspiration going, here's a link
to a winter project (two winters actually) of my friend Overland. He cooked up the stainless steel tubing himnself (!) and completed his 660 single with a Yamaha R1 Akrapovic Titanium. A big muffler, and what a sound! A bit like a rolling subwoofer.
