2015-2017 Mustang GT Fastback Corsa Xtreme Cat-Back w/ Gunmetal Tips Exhaust Sound Clip & Install

Hey, guys. Today, we’re gonna be taking a look at and
installing the Corsa Xtreme Cat-Back Exhaust with gunmetal tips for 2015 to 2017 GT Mustangs. This is gonna be a good option for someone
who wants a very loud cat-back and the cat-back that doesn’t have any drone at all. The Corsa Xtreme is arguably one of the loudest
cat-backs that’s available on the market. I’m gonna call it a full five out of five
in the loudness meter. It’s also top of the line when it comes to
both quality and fitment. This is gonna be a good option for someone
who doesn’t mind paying for those qualities. The Corsa Xtreme cat-back cost about $1,650. I’m gonna call the install a two out of three
wrenches in the difficulty meter and should take you no longer than three hours to complete. We’ll go ahead and show you how it installs
now. For this install, we used a 15-millimeter
deep socket, a deep 13-millimeter socket, a shallow 13-millimeter socket, a medium-sized
extension, a cordless ratcheting wrench, and a 3/8 drive impact. All right, guys, so we’re gonna drop our factory
cat-back as one big piece. The first thing that we’re gonna do is grab
a 15-millimeter socket. We’re gonna go ahead and loosen these two
clamps right here at our resonator. Then we’re gonna move towards the back of
the car and unbolt our two sets of hangers back there. So, we have two sets of hangers in the rear
here, one here right behind the diff and then the other set of hangers is actually up by
our mufflers. So what we’re gonna do is we’re gonna unbolt
them with a 13-millimeter socket, but we are gonna leave the hangers clipped into the body
still, it’s gonna hold the exhaust up for us. Okay, guys, you can see that we can remove
the bolt, but that the hanger is actually clipped into our frame right here at
the top. So, there are two bolts that are holding the
last rear hanger in place. There’s one underneath right here, and one
up on the side. We’ll do the same thing on the other side. So, at this point, we’re ready to drop our
cat-back. You guys might need a second set of hands. I have Tony here to help me. What we’re gonna do is Tony’s gonna unclip
the hangers from the body of the car then we’re gonna push backwards on the resonator
and then release it and we’ll drop the cat-back. So, here’s our factory cat-back laid out compared
to our Corsa cat-back. So, there’s a lot to say about the Corsa cat-back,
but the first thing I’ll say is that this cat-back, the Corsa Xtreme, is the loudest
in the Corsa lineup and it’s arguably one of the loudest cat-backs that you can pick
up that’s on the market. The other thing I’ll say about the cat-back
is that it is 3-inch. It’s full 3-inch from the X-pipe back and
it’s made of 304 stainless steel, which is gonna be the best option when it comes to
corrosion resistance and it’s also gonna give you the longest life of the product. So, since this is a 3-inch X-pipe, of course,
it does give you two adapters in case you guys are bolting up to your factory headers
and cat pipes like we’re gonna be doing today. If you guys already have some sort of 3-inch
system in place, you won’t need the adapters and you can just go ahead and bolt up your
X-pipe. Now, speaking of the X-pipe, this is Corsa’s
Double Helixx X-pipe. And generally speaking, an X-pipe is gonna
be louder than an H-pipe and it’s also gonna give you a little bit of a raspy tone. Of course, this Double Helixx X-pipe just
gives a little bit of a different path for the exhaust to travel through, so it’s gonna
change the sound of this just a little bit as opposed to a standard X-pipe. Corsa’s Xtreme mufflers are straight-through
mufflers and they’re gonna reduce back pressure too. The great thing about these mufflers is that
not only are they extremely loud, but they also have absolutely no drone at all, which
is great news coming from such a loud system. Finally, this cat-back ends in Corsa’s gunmetal
tips. So, we do have a couple of things that we
have to transfer over from our factory cat-back to the Corsa before we can go ahead and get
it bolted up to the car. And that’s gonna be our hangers, so we’re
gonna go ahead and transfer those over now. All right, so we’re just gonna pull our hangers
off of our factory cat-back. A little PB B’laster or WD-40 might help you
guys out here. And we’ll transfer them over to the Corsa. The first thing we’ll do is get our adapters
in place. So we’ll go ahead, use our factory clamps
for these, then slide our adapters into place, and then we’ll tighten these clamps down. So, now we’re ready to get our X-pipe up into
place. Two things that I have ready to go with me
are my clamps. So, I have two clamps on the X-pipe already. They are facing downward so that I can tighten
them once I get this installed. The other thing I have here is a pole jack. This is gonna help me get the X-pipe lined
up and into place. I am gonna leave the clamps loose until I
can go through and tighten everything down. Make sure it’s all lined up, but that’s gonna
be one of the last steps. So, the other thing to be mindful of with
this X-pipe is that this support bar down here at the bottom of your X-pipe down here,
this needs to be facing towards the ground. So, the X-pipe actually needs to be installed
in this orientation here with the bar facing towards the ground. So, now we’ll get our first muffler assembly
up into place. I already have my hangers, so we’re good to
go there and I already have my clamp positioned and in place too. Once again, I have this so that I can easily
tighten it from underneath the car. So, what we’re gonna do is slide onto our
X-pipe and then we’ll get our hangers clipped into the body of the car. So, I am gonna go ahead and get the bolts
in this back hanger here just because it’s going to make sure that our cat-back doesn’t
fall out of place. All right, guys, so we’ll grab the other side
and do the exact same thing. We’ll slide onto our X-pipe here. We’ll make sure we have a clamp in place and
then we’ll go ahead and get our hangers clipped into the body. We’ll also get the bolts in place in the hangers
on this side as well. So, what we need to do now is go through,
straighten out our system, and tighten up our clamps. We’re gonna start with the two clamps up here
upfront on our X-pipe. These are 15-millimeter clamps. We’re gonna go ahead and tighten these down. All right, guys. So, next, we’re gonna tighten these clamps
here for our muffler pipes. One thing you wanna make sure is that the
pipe is pushed up as far as possible, and you can just imagine where the tip is gonna
be. Before you tighten this, you wanna make sure
everything is lined up nicely. So, this right here is what I was talking
about. You can clearly see that this muffler is not
hanging correctly, so before we can tighten this clamp, what we’re gonna have to do is
push up on this and rotate this so that it’s sitting correctly, and what I might do is
actually use my pole jack to hold this in place so I can tighten this clamp down. So, I’m basically taking a peek, making sure
my X-pipe is sitting parallel with the ground. I’m imagining where my tip is gonna be so
that I can get this tightened down in the correct location. So, with this hanging correctly, we can go
ahead and tighten our clamp down. All right, now we can slide our tips into
place. Make sure you have a clamp on your tip before
you get it installed onto the muffler. Before I tighten that down, I’m just gonna
take a step back and make sure that it’s perfectly straight. All right, so we’re gonna do the same thing
on the other side. All right, last thing, and we can’t forget
to get our hanger bolts back in place here, so we’re switching back to our 13-millimeter
socket and we’ll get these tightened down. That’s gonna wrap up this review and install. Keep in mind that you can always check this

  2. Love this exhaust note. I have it with the same tips on my 2016 GT and it looks and sounds amazing. The cold start is very loud. If you park up against a wall it’s loud as well. My favourite is to leave the door open and cold start it. Oh man it’s so loud, it never gets old. I sometimes have to start it at 5:15am omg nothing subtle about this exhaust. Big thumbs up from me? Not changing it unless something even louder comes out.
