hey guys Stephanie with
americanmuscle.com here with a review
and an install of the CPE austenite
axle-back exhaust system fitting the
2015 and up EcoBoost Mustang we're gonna
be talking about a few different things
with this exhaust today but me and Lee
will talk about the sound of the XO back
the materials and the install the
install for this is easy it's a two out
of three wrenches on the difficulty
meter since there is some cutting
involved but I'll get more into that
later
the CPE austenite axle back exhaust
system is going to be something that you
should check out if you're looking for
one of the top-of-the-line high quality
stainless steel axle backs that produces
more of a tone down exhaust now the CPE
here isn't very loud but it is a
definite upgrade over the factory
exhaust I think that by steering away
from an overly loud system CPE was able
to create an axle-back that doesn't have
an obnoxious four-cylinder turbo car
sound to it you do still get some of
that sound with this axle back it
doesn't completely eliminate it but
facing the facts the EcoBoost is a
four-cylinder turbo car so that's what
its gonna sound like there are some
axle-backs that enhance that sound and
some that give the EcoBoost a little bit
of a different sound I would say that
the CPE here is in the middle of that
spectrum it doesn't make the EcoBoost
sound exactly like an import but it
isn't the smoothest sounding axle back
for the EcoBoost either like I said
earlier this is louder than the factory
exhaust and deeper but I wouldn't really
say that it gets too loud in the upper
rpms it barely has a change in noise on
decel which is part of the reason why I
say that this is a little bit of a
smoother sound to it the smoother
sounding exhausts are usually the ones
that give the EcoBoost a sound different
than an import so at the end of the day
I'm going to call this one a two out of
five on the loudness scale with one
being very quiet and five being the
loudest this axle-back can get even
louder if you ever decide to change
anything down the road
like your mid-pipe or your down pipe and
keep in mind that you're still fully
catted and that there are a ton of
different axle-back options for the
EcoBoost if this one isn't what you're
looking for
other than the sound this axle-back is
made from 304 stainless steel which is
top-notch when it comes to exhaust
materials 304 stainless steel will hold
up to the elements the best and you
won't have any corrosion
whereas materials like illuminate steel
tend to fail over time and on top of the
stainless steel this axle-back also has
a tighten finish for added durability
this is a satin finish that's going to
look good but you're only really gonna
see the tips anyway but this is just
another level of protection for the
stainless steel you're also looking at 2
and 3/4 inch piping here and four inch
tips that have that same satin finish
when it comes to price I mentioned this
earlier but the CPE here is going to be
on the more top dollar side but you are
getting a full two and three-quarter
inch stainless steel axle back that fits
well and delivers a different type of
sound you can expect to pay just over
$700 for this but don't worry if this is
out of your price range there are a ton
of other axle-backs available for the
EcoBoost with different price points so
you can always check those out
you're gonna be looking at the typical
cut and clamp design with the install
for this axle-back since to me to cut
all s550 axle-backs I'm gonna call this
a two out of three wrenches on the scale
but just because the cutting us at Falls
it's nothing difficult but I just
recommend some eye protection and a
fresh way to make the cutting easier
overall you're looking at about two
hours to get this all done a lift would
certainly make things easier for you
here but the job can be done on jack
stands as well if you don't have access
to one cutting the factory axleback
isn't hard just be sure to measure twice
and plan to mark where you'll be cutting
so you don't make a mistake
then you axle-back will come a new clams
for you so you don't have to worry about
that you go to install your new setup
it'll probably be easiest to leave
everything loose until you have it all
lined up and then tighten it down
wrapping things up here with the CPE
austenite axle-back exhaust this is a
two and three-quarter inch stainless
steel axle-back that's gonna give a bump
in volume but it's pretty calm at the
same time it's a smoother sounding
axle-back that doesn't have drone or
distortion to it and as always you can
