really dislike loud exhaust systems, and Chevy may be trying to strike
the right balance for a wide range of owners.
My latest C7 does have a user selected mode which very substantially
affects the exhaust noise level. At the loudest, it is, to me, downright
obnoxious, but I also admit that my winter car has been either a Lexus
or Acura sedan with extremely low cabin noise, just the way my wife and
I like it.
Certainly GM knows how to make loud exhausts but guessing it is a
deliberate marketing decision and one which allows the aftermarket
exhaust parts makers to sell a lot of replacement components.
Different horses for different courses.....
Can't agree more, some (meaning very few) of the Mustangs sound mean as snakes, most - not so much.
The C7 NPP can be tuned to your liking by the driving mode and even that sound can be tuned in the settings. Very quiet vehicle if that's what you want on long trips.
Thanks for the comments, guys. Besides being loud, the Mustang has a lope
like the 60's big blocks with high overlap cams. It is not the loudness
of the exhaust of the Mustang so much but it is the sound or lope. I
almost thought for a while there that the modern Corvette firing sequence
had changed and the lope disappeared.
I have been behind modern accelerating Corvettes when in caravans with my
club and under acceleration, the cars sound, not powerful, but bizarre.
There is more to making that sound than just opening up the pipes.

this thing out like the older Corvettes I've had, was very comfortable in t

The main reason Corvettes sound so anemic is because of cabin resonanace.
Testing in a C5 showed peaks at 1100 and 2200 RPM, right in the heart of the
cruising range. Later versions are probably about the same.
If these frequencies are not filtered out, the cabin becomes a giant
low-frequency echo chamber. After filtering, the result is the tinny, non
big-block, non-muscle car tone you hear.
