I have had approximately 100 miles of seat time with it in the Vapor. At first the sound was loud, like louder than I expected, but it has slowly started to quiet down and become more mellow. This is some what disappointing to me since I love an exhaust being slightly on the louder side even with cruising. There is NO DRONE that I can hear, nor can I tell when the MDS kicks in. Of course, when you step on it, its loud and very noticeable!!! I, also, love the black tips as well and think it completely finishes off the exhaust.
as much as I love the sound... I hate the exhaust itself. Its huge!! The rear pipes stick out like a fat guy in skinny jeans... The shipping weight was 60lbs!!!
So I now have two choices- keep it and ceramic coat the axle back part black so it doesn't stand out like a sore thumb OR sell it and go with the Kooks. As of right now, I will be going with the latter...
