STILLEN®
has
long
been
associated
with
Infiniti
tuning
parts
for
as
long
as
Infiniti
has
been
around,
creating
high
performance
products,
and
meticulously
crafted
exhaust
systems
that
have
proven
time
and
again
to
produce
the
maximum
horsepower
possible.
With
the
introduction
of
the
2016
Infiniti
Q50
3.0L
Twin
Turbo
V6,
STILLEN®
immediately
went
into
R&D
utilizing
their
many
years
of
experience
with
VQ
engines,
and
the
results
were
fantastic.
As
with
any
turbocharged
vehicle,
we
found
quite
a
bit
of
power
on
the
Infiniti
Q50
3.0TT’s
exhaust
system.
As
with
the
intake
system,
the
Luxury
Car
nature
of
the
Q
means
that
it
was
designed
with
Noise,
Vibration
and
Harshness
front-of-mind.
That
means
that
power-robbing
compromises
had
to
be
made,
the
end
result
being
that
your
Q50’s
3.0TT
can’t
breathe
as
well
or
make
as
much
power
as
it
should.
By
streamlining
the
flow
of
exhaust
gases
and
removing
unnecessary
restrictions
in
the
system,
after
dozens
of
prototypes,
STILLEN®
engineers
unlocked
a
26WHP*
and
29WTQ
Gain*.
Those
numbers
are
nothing
to
sneeze
at,
and
you’d
be
hard
pressed
not
to
notice
an
additional
29lb/ft
of
torque*.
*Results

The
STILLEN®
Q50
cat-back
exhaust
system
has
an
aggressive
tone
under
hard
acceleration,
but
mellow
during
cruising,
with
that
unmistakable
STILLEN®
sound.
The
free
flowing
performance
mufflers
and
tips
are
constructed
of
304
Stainless
Steel
for
long
life,
and
includes
a
limited
lifetime
warranty.
The
piping
is
mandrel
bent
for
smooth
flow,
and
fuel
mileage
gains
can
be
expected
at
cruising
speeds.
Designed
to
fit
beautifully
into
the
OEM
valance
or
as
a
compliment
to
a
STILLEN®
Rear
Diffuser,
this
system
looks
as
good
as
it
sounds.
Available
with
three
tip
options
to
suit
your
tastes
–
choose
from
Carbon
Fiber,
Polished
or
Burnt-Titanium
Look
Tips
to
give
your
Q50’s
rear
end
that
‘extra
something’
it
needed.
This
2.5"
Y-Pipe
configuration
allows
for
better
airflow.
The
Y-Pipe
than
connects
to
the
3"
Mid-Pipe.
The
3"
Mid-Pipe
than
carries
the
exhaust
gases
to
the
rear
of
the
vehicle
where
it
branches
back
into
2.5"
dual
rear
exit.
Dual
Mufflers
w/
Burnt
Tips
Upon
meeting
the
rear
exhaust
pipes
the
exhaust
gases
flow
through
the
STILLEN
engineered
and
manufactured
mufflers.
The
4.5"
bolt-on
exhaust
tips
enable
you
to
adjust
the
tip
position
for
a
proper
fit
no
matter
what
bumper
or
aero
you
choose
to
run
at
the
back.
Finally,
the
exhaust
note
is
mild
and
well-mannered
under
normal
driving
conditions,
but
quickly
turns
aggressive
and
authoritative
when
under
throttle.
