Hello girls and boys, since I am absolutely jealous of the noise heritage of my colleague, I would like to have the sound improved on my RK 2008. Since I myself have 2 left hands I asked my friendly one and he suggests: Screamin Eagle Air Cleaner Kit SE Pro Super Tuner Kit M Kit, Muffler, FLH ’07 as an alternative he suggested only to replace the rear silencer. Here come my questions: If I have understood everything I have read here correctly, then Is the replacement of the end-shell damper not the solution alone, because for this the engine has to be adjusted!? The Tuner Kit seems to be a “programming device” for the ELektronik. But I have read somewhere that this always works only with a motorcycle. Can anyone explain that to me? Thanks to all the greetings from the sun Frank
