I did post this somewhere else so please bear with me here.

Looks like there is a possibility that i'll be getting a great deal on a set of v&h duals with thunderheader slipons from a member.My question is my bike only has the stage1 with heavy breather.Am i going to have to reprogram once i install this setup.what would happen if i didnt do anything once the istallation is complete.I'm also assuming that others have installed similar setups w/o any further mods.

 

i'm running V&H with their cleaner,and slip ons. stage 1.. you should be ok as far as i know of. call V&H they'll talk to you.

 

You might need more than a stage 1 download with those thunderheader slip ons they dont make much back pressure.
