I have an 09 street glide with the V&H duals. They are loud and sound good. I have heard the Reinhart dual as well and they are loud and sound good. You can't go wrong either way.
I have both. The Bigshots Staggered on my '04 FXDL and the Rineharts on my '07 Ultra. Both sound great but the BS's are considerably liouder, and I am even running the quiet baffles in them. The Rinehart's on the other hand sound great when you get on 'em but are quite manageable in areas where you need to keep the noise down. For a tourer I would definitely go with the Rinoh's.
