Purchased a 2015 Commander Max XT a couple months ago with the CSI doors, windshield and roof. I love the machine but WOW is it LOUD riding in the cab. It gets a little better when the windows are down but it is still obnoxious. Has anyone found a way to make these machines quiet? It would be nice to be able to talk to the passengers while driving at speeds above 10 MPH. Any tips or advice is much appreciated.
