Welcome !!!!! kev will correct me if I'm wrong..but I believe (am sure) it is the same as a rappy 700. kev has a digi box on his pc111, it could be one of those..........
If you want to buy one at dirt cheap price call Simon Cope 01253 891087,(Dynojet Approved Dealer), plus he would know for sure if it is the same connection.
Anyway, what's the plan?? just a pc111, or some zorsts too?
A DNA Stage 3 airbox at around �400 is the way to go! (about the same price as exhausts, but a hell of alot more poke for your money!)
