Most are... What info are you searching for and not getting? Other than making your bike louder (personal preference), it will not gain you anything...
i do not run that system anymore but even with baffles, you will have a mid range dip, more so if you are stock.
i run a 2/1 system and notable improvements 5k+ rpm
if you ride below 3k, will not be much issues
So pull the baffles and see what you think. Maybe it will finally be loud enough for you. Maybe not, but at least you tried. Even with the loss of power it will seem faster since it's louder.
I have the standard baffles in mine. Running them on a Sporty. Just bought the quite baffles and am going to swap out over the winter to see if they deepen the sound a little.
definitely would not want that loud sound if doing hours long rides.
