Besides a taller windshield, (I have the 15 inch wind splitter). Get a set of wind deflectors fro HD. They go on the crash bar in front of the gas tank. As soon as I put them on I could here my stereo all they way up to 80mph or more. They send air over your head and it puts you in a burble with much less wind noise. They are only like $35, best upgrade I did.
