 Silencing
characteristics and the quest for exhaust efficiency: the two requirements
imposed on exhaust systems have a contrary relationship, and in
practice it is extremely difficult to achieve both. At Mugen, we
have continued to employ the straight configuration, with the design
philosophy that low exhaust pressure must be provided, and that
reducing exhaust resistance is an important part of the ideal exhaust
system. The straight configuration is widely used in racing, and
is ideal because, as the name suggests, it provides low exhaust
resistance. However, large silencers are generally required, as
there may be problems with mid to low frequency band silencing and
scattering of sound absorbing material such as glass wool with the
straight configuration. Incidentally, the inverted multi-layer expansion-type
silencer widely used by automobile manufacturers provides stable
silencing performance, as the sound passes trough several divided
silencer chambers, but involves the disadvantage of some output
loss and is larger and heavier than other silencers. As a result
of our quest for the ideal design for racing engines, Mugen developed
the "twin loop-type silencer," in which the pipe is twisted into
two loops and passes straight through the silencer twice. This could
be considered the ultimate arrangement, combining the concepts of
"absorption" and "intervention" in an ingenious manner. It surpasses
normal systems in power and torque over the full range, and provides
the required silencing and the clear Mugen-Honda sound.
