Currently Bub 7's have only the standard baffle. According to Bub there are quiet baffles in the works.. I think they sound great and have a very deep rumble.
I put BUB7 true duals (crossover pipe removed) on my 09' FLHX. I found that the rear pipe hits the left side-panel and required a few beers and some late night garage engineering to make it fit without touching my new paint (I'm not impressed BUB). BUB needs to correct that problem since the 09' and later have larger left side-panels. They are louder pipes than the Rhines, and a whole lot louder than stock. I'm currently looking to put quieter baffles in them so I can hear if I'm pulling away from the sirens behind me.
