Those are Sideburners and if you don't want to deal with maps you can run the FI2000. That's what I have now. Works great on my VTX. :bigthumbsup:Austin109 said:Not sure I like the bags but are those sidecutter pipes? I'm thinking about putting these on my 109 with a PCIII but they don't have any maps for us yet. What happens when you install a PCIII with no maps can you change anything and if so how would you know if the improvement didn't mess something else up?
