From what I can tell of (1) vid on Uboob, the Monsters sound pretty good, but the guy in the vid is hot-doggin the hell outta the bike,, never really 'rides along like a normal human',, so

Was not aware of any removable baffles in the Monsters. Cobra 6-2-6, yes, V + H,, eh,,,

The '8 Ben' factor is enough of a deterrent for me to divert funds elsewhere, especially when I'm not looking to 'excite' with pipes,,, just here to be mellow,,, and the OEM does a good job considering what it's given to work with. Also does it with less weight than most aftermarkets, so,,,,, depends on what ya want.
