Harley guys/gals love that unmuffled "potato potato"....me? notsomuch. To
make it worse, on most all Harleys the throttle is more of a volume control
than a discernible source of increased forward speed. If you're going to
make that much noise, at least be fast.
Any Honda/Acura or Miata four cylinder unmuffled is ear pain.
Mazda rotaries require mufflers to sound less than annoying. Interesting
engines, though.
Inline sixes, V8's and V12's all tend to sound right, no matter how muffled
or unmuffled they may be ;-)

Definitely one of my top 'angry hates' :) what do people see (or should I
say hear) in that awful racket?
I think all loud noises should be judged by the benchmark of 'would you
rather your toddler kept sleeping or should they be woken up to experience
said sound?' If its not worth being interrupted from an interesting
conversation from (and a small block ford usually is), I don't want to hear it!

Of course, we also need to differentiate "good noise" from "bad noise"...

True enough, but the LAT73/LAT74 headers and exhaust, that these mufflers
were part of, were not really intended for stock engines.
My Tiger came to me with a five-bolt 289 with ported and polished heads, a
Holley 600 and F4B manifold, and a pretty lopey cam. 'Quiet' was not
really in its repertoire, although sticking with a 2 inch exhaust system
does
help keep the overall noise level down compared with 2 1/4 or 2 1/2 inch
pipe, at the expense of some performance at the high end.

I can tell you that in using cheap old glass paks with a stock engine and
the same mufflers with a hopped up 302....they are much, much louder with
the 302. I shouldn't think a stock engine would be that difficult to
muffle.

Mike,
Here's a picture of what I think are the Mitchell mufflers - these are
what was on my Tiger when I got it.
For the rest of you that won't get the picture:
The body is 24" long, 3x5" oval, 2" in and out. Contrary to what I
remembered, the hangers attach 5" rearward from the front of the muffler
body - there is only about 20 inches between where the hangers attach on
the chassis and the rear axle tube.
I do recall the front of these mufflers pretty much touching the
rearward part of the underbody X frame, just behind the little exhaust
pipe notch in the X. The sound of these mufflers was pretty aggressive,
but it went well with the rest of the system and engine.
I would also be concerned with the amount of sound suppression that's
possible in a small diameter muffler such as the chambered ones in the
link below. It may be that with proper choice of all the internal
volumes, they get noise cancellation at most of the frequencies of
interest, but it seems to me that the overall result would still be
pretty dependent on the rest of the package, i.e. engine displacement,
cam, and the diameter of the rest of the exhaust.
