Default Exhausts sounds: Mustang vs Corvette

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.
