I too have V&H BSS on my 13 Deluxe with quiet baffles. The quiet baffles gives me a deeper tone. I have the SE race tuner and the dealer has tried several times to get the burbling out and cant. However it only does this when i cut off the throddle at less than 2000 rpm. So, it isnt to bad and I have finally got used to it. I aint throwing any more $$$$ at it.The pipes do sound good.

 

I have BSS with "quite baffles" on my 05 95ci Fatboy with SE 204 cams and they are loud but not obnoxious and if you dont twist it up into the higher RPM it is actually very reasonable, No popping or gurgling on my bike but it has been tuned using power Vision and Dyno

 

The previous owner put the BSS's on my Heritage. I don't know which baffle are in them but I love the sound.
