I am giving my Rappy the three mod make over tomorrow.
(DMC Dual's, PClll, GYTR intake w/ K&N Filter, and 15T) I don't plan on running the "Quiet Cores" in my DMC Duals, but sometimes here in Calif. the rangers do check Db. levels, so there may be times I will have to have them in. My Question is - will putting in and taking out "Quiet Cores" effect performance of the bike and will it have an effect on the "Map" i'm using ? Give me your input. :thumbsup:
