Just finished installing the new Rinehart slipons, the power copmmander V and the new air intake on my 09 ultra. Took it for the first ride and love it so far. The Rinehart slip ons are not too loud but sound really good. Was a little worried about doing it my self but it was really easy. Can really tell a difference in the power, can't wait until a hot day to see if it runs cooler.
