V&H Quiet Baffle Test.
Dont know if this was ever posted before.... but here it is.
http://www.cyclespot.com/baffles.html
We decided to find out how much quieter the new "Quieter Baffles" from Vance and Hines really were. For this test we again utilized our "Test Mule" (2003 FXDWG) as it was equipped with the Python Quick strikes (AKA Vance & Hines Big Shot Staggerds but without billet caps and different heat shields)
We picked up a decibel meter from a local electronics store, and set it four feet behind our "Test Mule". We did not move or shut off the meter for the duration of the tests.
First we ran the bike at normal idle speed with the factory baffles installed, and recorded the readings.
With the stock baffles in place, the decibel output was 98db.
Next we removed the stock baffles entirely to establish an un-baffled Db.
(Due to EPA requirements many of the newer Vance & Hines and Python Quick Strike pipes have these bolts covered, if yours does, you can either mark where the bolts are under the heat shield, remove the shields and drill an access hole, or simply remove the heat shields each time you change baffles)
Here's what our stock baffles looked like after being on the bike for over 3000 miles.
With the baffles out, we ran our test again, our un-baffled readings came in at 104 db.
Next we opened two boxes of the new V&H "Quieter Baffles" V21869
Since we already had our stock baffles out, it only took a few minutes to install our new baffles.
Once the new baffles were installed we took another decibel reading.
The new baffles came in at 92 Db, a full 6 Db lower than the stock units and a full 12Db lower than no baffles at all.
There was a noticeable deeper tone to the engine, and we decided to test drive the new baffles. At lower engine speeds we noticed a significant improvement in torque, and mid-range power with these new baffles. All in all, if your looking for a little less noise, and a little more low RPM power, the new V21869 baffles are your ticket.

RE: V&H Quiet Baffle Test.
Thanks for the info, I put short shots on over a month ago put due to weather here in NY have not been able to ride much. I like the sound of them, but once it warms up and my wife starts riding with me she could have something to say about it. If she thinks it is too loud I think I will try the quite baffles.
