Hi @ all, I would like some advice on the topic of sound of a Harley ( injector ) Since a Harley ( for me ) should listen like that ( in the stand volumic and full, and during the ride she may like to bang something while giving gas ) well I guess everyone here knows what I mean…:-) That the “old” HD ́s have a sound is well known to me, but does this also happen with the “new” ones ? ( so from Bj 2002 ) I think so in particular about KAT etc Now my question: what does it cost if one of the “new” ones ? ( so from Bj 2002 ) I think so in particular about KAT etc ” Rennleitung” is stopped (because illegal) ?? Which system is good for the sound what and is legal ??? Thanks in advance
