I have the V&H BigShots on my VTX and I love the way they sound, very deep and not blatty at all. I have the standard baffles in and they've even gotten better as time goes on and miles pile up.
They can get pretty loud when you get into the upper revs or wide open throttle, but I can easily ride through my subdivision at 1-2am and keep it quiet enough not to disturb anyone or my 2month old son, even when pulling in the garage, which is right under his room.
I also wear earplugs while riding to protect my hearing from wind noise and the BigShots are still very noticeable then, can easily ride and shift by sound with the plugs in.
