Air Kit. Air Kit I meant. This thing for instance: http://www.cruisercustomizing.com/detai ... VTX_1800_C
A lot of people talk about the VTX not getting enough air which limits the hp. I guess more is always better, but my original point was that power is not a concern to me on this bike.
I've seen those Big Shots listed for as much as $600 but I was able to get them for $495 online. It's still a lot of money, but there you have it. Again, good luck in the decision.
but anyone else wanting pipes might want to check out their prices i think they will beat any one else.
