I suspect mine has the baffles removed; I'll have to compare it with a stock Dubya at some point in the future. Looking up the pipe, I don't see the two tack welds that are supposed to hold the baffle. The pipe looks single-walled at the end. I can see a baffle screen about a foot up the pipe but it's not at the end of a "removeable" baffle.
Mine is very quiet at idle, but seems much louder on hard accelleration, especially above about 3500-4000 rpms.
I like mine the way it is, no intention of changing it.
