Having sold my Spyder F3-S, for sale is a RLS Twin Kaos slip on pipe. Cerakote finish plus the polished tips. This gave the Spyder a nice throaty sound while excellerating, but was barely noticeable when cruising. It was used for a few months and maybe 3000 miles.It bolts on using the existing clamp and takes less than 5 minutes to install. I paid $460 plus shipping, selling for $250 including shipping in continental United States. I prefer Paypal for payment.Fits An F3 or F3-S
