Thought I'd add, the exhaust isn't that loud at all now, I believe it was the fitment of it was touching on the cradle which resonated the drone through the cabin, as it was really bad, I couldn't understand how you other guys with the Niz exhaust could handle it. Haha Its fitting better now. Still not perfect though, when it's hot and I'm at the lights after doing bit of a 2nd 3rd it slightly vibrates on something. These things are a super tight fit.
