I think I put mine in the S280 dyno thread.  I'll find mine.
Eggroll guy, sure cancel your order and I can get one headed your way.  PM with your info and we can go from there. 
That all said. I have no complaints with the noise level of my OE BOV on the S280.  To me its not to loud but louder than stock and I am running all OE pre turbo piping, and airbox lid.  I do have the Mountune lower box.
