Stop in for a cup of coffee

So, while driving Dart in real world conditions, found the Interior Drone to be excessive at 2K Rpm, right at my cruise Rpm. So, changing mufflers from flowmaster series 40 to series 50. Both delta flow. Hope it does not tame it down to much....BUT Simone will be riding in car for hundreds of miles so it has to be bearable, which it is not now....
