IF its drone you want to rid your car of... some members say by putting some deadening on the inside (trunk floor) near the rear seat where the MULF bluetooth box is... that quiets the drone. But I would only do that IF your car does not have BT.
Also... the resonator on the 1M mids is a fake. So by installing the N55 mids, you will get rid of the drone(bc it has a real resonator) and you will also make the exhaust louder bc it has not secondary cats. Win-Win!!
Read thru that above "sticky".
