Well this August I made a longstanding wish come true and made the pilgrimage to Sturgis. 5500 miles round trip from Ft. Lauderdale FL and back. This was our first long trip (23 days) living on the bike day after day. When I asked the wife how she liked it all she could do was point at her ears and say in a loud voice, "WHAT?" Apparently my Rineharts, which sound like so much sweet music from my seat, are a wee bit louder where she sits. So much so that although she wants to go on more trips she's begging me to turn down the exhaust noise. Any advice from those of you making long trips with a back seater? What pipes/exhaust systems sound good but don't deafen? Currently running Rinehart slipons with SERT and SE air cleaner, (basic Stage 1) on an 09 Ultra. We ride with 3/4 helmets and intercom. Babs is signing "HELP"!
