This
ISR
test
pipe
is
a
high
performance
part
that
is
intended
for
use
in
an
89-98
Nissan
240sx.
The
upgraded
test
pipe
replaces
the
stock
catalytic
converter,
increasing
exhaust
flow.
Upgrading
your
catalytic
converter
to
ISR’s
test
pipe
is
a
great
way
to
improve
the
performance
of
your
engine.
This
is
because
catalytic
converters
are
designed
to
regulate
the
harmful
chemicals
that
are
coming
out
of
your
car.
Stock
converters
can
certainly
do
the
job,
but
usually
at
the
expense
of
engine
performance,
as
they
constrict
your
exhaust
flow.
An
upgraded
test
pipe
will
take
care
of
the
chemical
reducing
process
that
your
catalytic
converter
handles,
while
allowing
for
a
greater
flow
and
overall
better
engine
performance.
This
kit
includes
all
of
the
gaskets
and
hardware
required
for
a
complete
install
and
features
extremely
high
quality,
TIG
welded,
stainless
steel.
Updated
flanges
are
water
jet
cut
from
thick-grade
stainless
steel
plates.
All
ISR
Performance
flanges
are
strong
and
well
suited
for
high
temperatures.
