Slip-Ons without a tuner?

[Martz2111]

I have a 2017 Street Glide. I already have 4.5” Street Cannon slip-ons with a Screaming Eagle Street tuner. If i would go with 4” Vance and Hines would I have to get another tuner?

Are you not happy with the 4.5 Street Cannons? I believe that you might have to go back to your local HD steeler to have a map download for the 4 inch Vance and Hines. I’m no expert but I think this is one of the drawbacks to the HD tuners. Other tuners allow you to download maps to the bike via your computer or other means.
