I had the CFR pipe on my last V and with no baffle I called it an ear bleeder. I would probably rate it an 8.5 to a 9 on the loudness scale with 10 the highest (only because I probably have never heard the loudest pipes available). I then heard a set of Bubs w/o baffles and would rate them about the same. How do the V&H powershots rate on that scale w/o any baffles. I made my own cone baffle for the CFR and found the pipe loudness very tolerable.
