I got a pair of bubs and pulled the baffles in 'em, now their so loud they hurt my ears at idle. Its like I can feel my chest and ear drums pulsing with the sound. I imagine soon I will lose my hearing completely. I can still hear them even going seventy miles an hour pretty clearly. I would imagine that the whitneys, which are straight through pipes, would sound similarly loud, and it's a lot more cost effective than gutting a nice set of Bubs. If I had it to do over again, I'd just get the whitneys. As it is, if you read the other thread, I'm trying to figure out a way to tone them DOWN just a wee bit, at least at idle, as they are brutally loud at this point. They would definately rival about any harley for sound.
