STILLEN
Race
Pipes
replace
the
stock
catalytic
converters
for
unrestricted
maximum
exhaust
flow.
As
race
only
parts,
they
delete
the
catalytic
converters
and
are
not
street
legal.
The
Race
Pipes,
combined
with
STILLEN's
new
performance
headers,
produce
big
increases
in
power
and
torque.
Contributing
to
the
performance
gains
along
with
the
straight-through
free-flowing
design,
is
an
expansion
chamber
that
promotes
more
efficient
exhaust
scavenging.
For
example,
the
combination
of
STILLEN
Headers
and
Race
Pipes
yield
performance
gains
of
16
hp
at
@
6200
RPM
and
20
lb/ft
@
3800
RPM
at
the
wheels
for
a
2003
Nissan
350Z
as
tested
on
the
STILLEN
Dyno.
With
STILLEN's
18
years
of
experience
in
designing
and
manufacturing
Nissan
performance
parts,
you
should
have
complete
confidence
that
every
STILLEN
product
is
of
the
highest
quality
and
has
under
gone
extensive
research
and
development
before
