OK, I have a 2013 CVO RG, which has Fullsac DX header pipe and Reinhart 4" slip-ons. I very happy with the Fullsax header. The problem is with the Reinharts - around town or for short rides they are fine. However, for a 500+ mile trip, my ears are still ringing the next day (and I'm wearing earplugs and a 3/4 helmet).
My Dyno Tuner says I should go with the V&H High Outputs which have a deeper sound and not as "harsh" as the Reinharts. Another option might be the V&H Monster Rounds.
Any experience here? I like the looks and the sound (from sound bites) of the HOs but going on a 500 mi ride might be different. Thanks for any imput.
