Work finished, Refrigerator & Muffler Fix & Replace

[Pete Masterson]

While the bus at idle seems to have the same noise level with the
old, worn out vs. the new muffler, I do notice that while underway
it's quieter. This is especially noticeable when the jake brake cuts
in. I also notice that the jake brake seems to not have quite as much
braking effect as before the muffler was replaced.

I don't know what legalities are involved with a straight-through
pipe -- for example, in Colorado, the law requires that jake brakes,
if used, must be "muffled." However, when driving through Colorado
with my old muffler, I never seemed to attract the attention of the
state patrol...
