Columbia?The road noise is all tires/road surface (and the fact that it has a much tighter suspension than a Lexus). I-20 where I live has some older rough pavement that is ridiculously loud. The new section that they just paved is Mercedes S class quiet. Pretty amazing difference. I had the same problem in my Civic where switching from Conti pro contacts to Michelin touring dropped it 1dB. Putting insulation in dropped it by another 1dB. Noticeable but not amazing.
No, west of Atl before the AL state line. But I've heard that SC has some terrible roads, too! They are in process of paving sections from Atl west and the new pavement is amazingly quiet- until the trucks destroy it.Columbia?
I don't think he is expecting a Mercedes level of quiet, just wants to reduce some exterior noise. Nothing wrong with that.Don't expect Mercedes cabin volume from a Mustang OP. Lol are you kidding me? Don't drive a sport/muscle car if you can't handle a little bit of NVH.
