Slic, I've had both versions on my bike. I was sent the unwrapped by mistake when I ordered the pipes, they were too loud for me at cruise. I sent them back and got the wrapped version. For me it was a noticeable difference. To get the baffles out, you would need to take the mufflers off the bike and pound them out from the front opening. I would think sooner or later they would need to be rewrapped. But you could call D&D to check if the baffles were the same on both with just the wrapping making the difference. Hope this helps.
