Noise Proofing
Does anyone know what the differences were between the RX330 and RX350? The RX350 seems to have much more noise reduction in the cabin when compared to the RX330. Did they use additional insulation on the floor/carpet? Was there additional sound deadening spray that was sprayed into the wheel wells? I would like to know what differences there were for noise proofing between these different models.
