Hi, if you are interested. I do have the stock, unmodified, perfect condition slip on OEM Mufflers for a 06 R1. I would be willing to let them go for $50.00 plus shipping. I just need to find out how much shipping would cost to ship them to the bay area from Calgary, Alberta , Canada. If this interest you, let me know. I will try to get some pricing for you tomorrow for the shipping costs.
