Cue the orchestra. We tuned these mufflers to provide an exhaust note with some extra deep bass. You get the rumble you want and enhance that famous Harley sound, while preserving the peace with your neighbors.
Just put these on a 08 Ultra Classic with True Duals, and while I like them, they are on the loud side when at idle, going thru the gears, downshifting and pulling power like going up a hill. At cruise they mellow out and sound good. What they need is a disk at the front end of the muffler to force the exhaust to go thru the matting material and make them just a little more quite and build some back pressure. In the stock form I think you might draw some attention from the police. Also if you had a 2010 and up stock exhaust with the catalytic converter it might make the muffler a little more quiet. As much as I like them I think I will change them out for another HD muffler.
A great addition to a high-performance motor, or for the rider that tours in extreme temperature conditions, the Screamin' Eagle cast-aluminum oil pan is designed to increase the oil capacity by 1.5 quarts over the Original Equipment pan. Increased capacity means the oil cycles through the engine less frequently and the oil can remain in the pan for a longer period of time.
