been stressing since i did my mod, as it so much louder - specially on the backfire! but as you guys pointed out, the Harleys are so much louder! mine was also done in part as a safety feature in traffic (as we are allowed to lane split).
i also think it always sounds louder for you than it does for other road users, as one does tend to be more aware of it. seems like the cops over there give you guys sooo much grief!?
