I have a Warpspeed 2.5 Y-Pipe, stock cat, stock b-pipe, and Flowmaster DeltaFlow 40 Series muffler. I love the sound of my car, very very very low, sets off car alarms, but I hate the droning on the inside of my car. Could I try insulating the floor of my trunk around where the muffler is with dynamat or something to reduce the droning in my car???

Or my other option would be to get a larger resonator installed, does anybody know of one that would be larger/quieter than the stock resonator?? I almost am thinking about changing to a Dynomax muffler because I have heard that they are probably the quietest muffler available for a maxima. Suggestions??? Thanks.
