very loud they don't make a lot of friends.
I dont think they are loud and neither do people I've ridden with. Water routing has a lot to do with it. I also beleive that different hulls contibute to volume of a given motor
Even the baffled tdr boxes don't have baffles.
huh ? baffled boxes don't have baffles ? ,,, I have one on my sxr 800 deepersound not too much louder .. BUT now dropping an 1100 in .. hoping it will be ok
