I've been contemplating that modification to my 560 as well, specifically the rear muffler. No sense in driving a shiny classic with a rusty piece of pig iron hanging off the back of it I figure. As near as I can tell, as recently as a few years ago there were several stainless systems available for the 107, but I haven't found anything still in production. Performance Products used to advertise a stainless performance muffler for the 107s in their catalog and I was able to pry it out of them that it was made by Remus, but all the resellers I've contacted are out of stock. Eisenmann made a system as well, but I've had the same luck tracking it down as well - none. There is a company called Time Valve (www.timevalve.com) that makes stainless sytems, but they're just replicas of the stock system. Probably not what you're looking for either. The best lead I've gotten was from a company called Status Imports (www.statusimports.com). One of their sales guys sent me a link to a supersprint system that they're going to be importing. Looks pretty sweet. That reminds me, I haven't harassed them about it for a month or two. I'll let you know if I find out anything useful...
