I tell ya this. I have a stage 2 Screaming Eagle kit with a re-map. Bought the bike with V&H muffs. Could not stand the resonance at 70 mph on the super slab so I switched back to OEM muffs. The only difference is better bottom end to medium end torque, a little less giddy-up at the upper end of the rev range. Give it a try. You might not notice anything at all or if you are not impressed, switch it back. Oh by the way. Great looking bike and welcome to the forum.
