While in process of testing newly rebuilt K321 for my second CC149, I had measured sound pressure levels (3 feet away)
using two different mufflers - CC149 factory muffler and Nelson muffler.
As expected Nelson muffler produced around half the sound level (for tech savvy -5.5dB).
Although a good number, but barely perceivable to an average ear.
