I use an android app called Road Warrior. I've had great luck with it. I don't know if there is an iphone version or not. It will let you plan a route with waypoints then optimize your route.
I have a set of OEM mufflers from a 2008 RSV that the previous owner had swapped out and gave to me when I bought the bike last year. They look to be in great shape, except for a few scratches on the bottom.
