I just removed my almost brand new Screaming Eagle II slip-on mufflers and replaced them with a Vance & Hines 2 into 1 exhaust system. The SE mufflers were great looking and sounded good, but weren't loud enough for my tastes. The V&H pipes sound alot better (louder) without being obnoxiously loud. By the way, I will sale my SE II slip-ons in perfect condition for $100 plus shipping. They will fit the pre 2007 Deuce, Fat Boy and Deluxe models. Call me at 210-710-1215 if interested.
