I was at the local dealer today and he had bikes set up with Indian Stage 1, CFR, and Vance and Hines pipes. It was a great opportunity to audition each. The V&H were good growl, but very loud. The Indian Stage 1 were much more subdued than I thought, not really any louder than stock, but a lower growl. The CFR was in the middle, and just right for me. Very, very, deep growl, but not loud enough to overpower the radio or conversation. They have them now for Chief, but don't have the brackets released yet for RM. Not sure about the rest of the line. For sure, in February (bonus time) I'll have a set, or maybe two, on the bikes.
