I want to say mine's getting louder and sounds great. I'm nervous about making it louder mostly because there are some places in the rev range that don't sound so good to me, like particularly at idle. I've heard it referred to as a parallel twin with a miss. I'd hate to amplify that sound. On the other hand, you guys are more experienced with metric cruisers than me, so if you say it'll sound great, who am I to argue. I think the HD and Duc set the standard for me. I did have an RC-51 and loved the way it sounded, but I'm not sure that sound would be right for a cruiser. I would have to hear a 109 with pipes before I'd ever spend the money. I would appreciate lighter weight and a bit more power too for the money. I like the stockers, but they are BIG. BTW, Has anyone else noticed the pressure change in your ears with the engine stroke at a stop light? Weird.
