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?
