Buzz noise 3000 rpm

[thprcz]

Hello all, sorry for English language, i don't understand Italian language. When i'm driving (or neutral, park car) my rcz (2011, 200HP) around 2800-3000 rpm i hear annoying (buzzing) sound around the air filter has anyone had a similar problem? I tighten all bolts, replace rubber holders for filter, checkeh exhaust leak, exhaust shield, sound resonator and there is nothing better.

I think max is right the rev range seems that of the butterfly membrane of the sound System, maybe it is split
