I'm fitting a 2:1 3" system (628-71570) onto my 2010 harley crossbones. my problem is that the crossbones factory exhaust is fitted with a cable operated valve (Active exhaust valve?) and there is no mention of what to do with it in the exhaust instalation instructions. Please could you advise me about the correct procedure.

That is a EU model, we have no info on that here in the US.
Suggest contacting the supplier for details.
