"Quiet"- sure, from your perspective. What about those outside the vehicle? Including those who might be trying to nap or some such.

I agree that is why I mentioned I had changed two things. I plan to close the cutout and check mileage so I can tell how much is due the new cat.
Re quietness, I have been watching pedestrians and they do not turn and look at me or otherwise react. I realize this is crude test and I recognize that the truck is nosier than stock. My point is that with the after cat cutout and tail pipe to the rear axle, it is surprisingly quiet.
