It being louder than I expected was my initial impression too. I think I am finally getting used to it, though it does tend to get pretty low and bass intensive in the 1700-1900rpm range with a steady throttle. I usually try to keep it out of that range while cruising which isn't too hard to do, unless you live in a hilly area.
Rob, did the K&N drop in filter really reduce the noise? In all my experience aftermarket air filters/intakes have made the engine and muffler noise significantly louder.
