to get that sound you honestly would need to out it a short ram or cold air intake and switch out to an aftermarket diverter valve. while the dealer may complain about these, you can just put in the stock airbox and stock DV if/when you take it to the dealership.
i mean how many times to you go in for warranty work anyways? and switching the stock airbox and dv would take you all of 45 mins.
