I'm thinking of installing a set of Klock Werks Super saver Slip Ons on my /09 Ultra. I've already done the AC as well as added a fueler and am now ready to finish the stage 1 with slip ons. My question is: has anyone installed these slip ons and how do you like them? The price is right, I like the looks and I like the idea that they're not really loud when at cruising speed on the highway. The last thing I want is a head ache at the end of a long ride. Comments please.
