I was looking through their PDF, and it does not have any info on my set up. I have removed the AI and airbox, stock needles (apparently with 2 shims) on a 2005 America, and have removed a couple of baffles on my stock pipes (not all of them because it was too loud).
No airbox means no info available. I can guess, but that seems like a bad idea for me to do at this point.
