I'll be honest. My bike just didn't like that setup. It never run right with any of the maps we tried. And to top it off, I smelled like exhaust fumes when I got off the bike. I liked the looks but I really like the Toce system. I know that's not much of a sales pitch for the S&S setup, but that's why I changed to the Toce system. If you can afford to go with that system, do it, it's awesome and my bike loves it.
