Kind of like the Ducati, but lower pitch, but still different somehow. I guess the 45-degree V-angle makes that odd pulsation that you can hear as different from the 90-degree motors. It wasn't like you'd think, though, like a "loud pipes save lives" cruiser exhaust, although that may have just been a perception based on being around other loud racing pipes.
I had no video with me, and I wish I'd taken the camcorder. Wouldn't have been able to shoot much, because I was working the event at a corner station.
