“silence”

101.6mm
main

withstands
over
1000ps
equivalent
to
a
racing

exhaust
system.
When
the
valve
is
closed,
the
large
capacity
silencer
and
dual
60mm
long
exhaust
pipes
maintain
the
silence.

As
the
tuning
level
is
advanced,
implementing
“silence”
and
“high
power”
together
may
be
difficult.
But,
with
2sx
Muffler,
it
is
possible
by
the
switchable
valve
equipped
with
this
exhaust
system.
The
valve
controls
the
exhaust
path
depending
on
the
engine
RPM
so
the
exhaust
system
can
withstand
high
power
maintaining
silence
at
low
speed.
This
valve
makes
two
exhaust
paths.
The
valve
is
operated
by
an
electric
motor.
The
valve
is
connected
to
the
electric
motor
with
a
control
cable
to
transmit
power.
The
electric
motor
is
automatically
controlled
by
a
controller.
*The
controller
is
a
purpose-built.
The
engine
RPM
signal
and
speed
signal
are
required
to
connect
to
the
controller.
The
valve
opens
and
closes
automatically
according
to
the
engine
RPM
and
speed.
This
exhaust
system
with
the
switchable
valve
can
implement
“silence”
and
“high
power”
together.
