I still haven't been on the highway but my observations from local driving:

> road noise seems to be markedly reduced. Less crashing over bumps, grittier asphalt doesn't seem to hum and intrude the cabin as much and it's a generally more pleasant place to be. It could be a different story at highway speeds but my initial impression is positive here

> it seems to have done nothing to reduce MPE drone in the cabin. I've made a point of driving around in that droney rev range between about 2700 and 3000 rpm and it seems every bit as loud as it did before

So far I'm glad I did but I wish I could do something to reduce the amount of drone that gets into the cabin. It's headache-inducing on long trips.
