You can go to youtube.com and type in royal star venture and there is a couple audio clips for the nasty boys. I have the nasty boys on my 2008 tour deluxe and bub's on my 2007 venture. The bub's are quieter but still have a deep rumble. The nasty boys get comments from everyone. They have a deep rumble and they really crack when you get on it. I have a lot of Harley friends that like the sound of my pipes better than their bikes. You can get a pretty good deal off of cruisercustomizing.com. You will want to get a good set of chrome clamps because the ones they send are really cheap and not chromed. The nasty boys sound like a small block V-8 taking off.
Good Luck,
