HI ,
I have 2013 HP4 no 2367. I have taken the Akrapovic exhaust off and replaced it with a small AR and link . I now have to put it all back on for a track day at croft next week.
can you tell me if I need to connect the butterfly valves . I struggle with basic mechanical stuff along with my spelling. the cables are not in use with the AR exhaust, however do they need to be connected and functional with the standard exhaust.
Thanks Jack sprat.
