Ok I had V&H Basics with stock headpipes for a while. I then went to dresser duals and kept the basics. The sound difference was there but not dramatic volume wise. The main difference was in tone and character. You can truly here each side fire at idle so you get a true stereo sound. Overall I would say it did get louder but much.
Next I bumped it up to a 95 and added an Andrews 26 cam. Louder still and more of a lope but not obnoxious at all.
Finally, I swapped the Basics out for a set of Samson 2 1/4 Fishtails with baffle. Ok, now she is loud
