I've had some loud pipes in the past, and I've loved them all, but when we bought the new CVO, my wife and I decided to compromise (just a little) on the loudness. I know this goes against the grain for many of you out there, so I apologize in advance!
Anyway, with having the awesome new Boom Box 6.5 and us doing a lot of riding, we wanted to be able to hear the stereo a little better and also hear each other without yelling, so after doing a lot of research, I installed the Vance and Hines Power Duals along with V&H Monster Rounds. We kept the same SE breather and added a SE Pro Tuner and dyno time.
The results were impressive. The throttle response is pretty much instantaneous now, and just WAY BETTER than stock! I'm only developing 108 ft lb of torque, but that's plenty for us, and still tons of fun.
But the sound was what we were after. This is my 4th set of V&H pipes, and while they don't sound as "Harleyesque" and percussively loud as my Staggered Long Shots on my old Heritage did, they produce an impressive low rumble that lets people know a Harley just rode by!
We still have to talk loudly, but we can hear each other now, and the radio only has to be at half volume to be heard well.
Anyway, we like the new setup, and I gotta say the Power Duals look muscular and awesome! Plus the exhaust tips on the Monster Rounds are a classy finishing touch!
So if you're looking for a more sedate sound, while not losing the low slap and percussive rumble that we all want, you could do worse!
