Just to stir things up... It seems that with
exhaust systems, the exhaust consists of two parts which should be handled
differently. Part 1 is the exhaust gas flow which we
want to flow out with little restriction. Part 2 is the
exhaust pulse which we try to attenuate, breakup,
etc. These two are like the difference
between wind and sound-waves. In the
past 24 hours or so, I've been wondering about using anechoic
chamber principles to attenuate the pulse. I have
a specific layout in mind which should tend to attenuate the pulses
while not interfering with exhaust gas flow.
Anybody hear of such a thing?
