    Review & Installation Video

    Review & Install Video

    Justin: So, the Corsa Sport is a system that's very near and dear to my heart as it's one of the few that I've had the pleasure of installing on my personal S197. And honestly, guys, I've no intentions of taking this one off anytime soon because it just sounds so darn good, especially when paired up with a set of catted long tubes and the corresponding X-pipe. But enough about my car, let's talk a little bit more about the sound clips that we just showed you guys at the top of this video. And for reference sake, the car we did use had stock manifolds or headers in place and just basically had the Corsa Sport cat-back rocking. And the sound is awesome. Just the right amount of bark, in my personal opinion, without being too loud or too over the top. So, going to my patented and very much scientific wake the neighbor scale, I have the Corsa Sport coming in at a robust four out of five on my one to five to one to wake the neighbor scale. Yet you're getting some volume here, guys. Don't get me wrong, this is not a quiet system but at the same time, it's not gonna be nearly as loud and unruly as that Corsa Xtreme or other five out of five systems out there.Now, if this is the first time you're checking out a Corsa exhaust system, then one thing you do need to be aware of is that yes, again, you are getting a good amount of volume out back but inside the car, things are going to remain extremely quiet, thanks to the company's patented tech known as RSC or reflective sound cancellation. Now, this just allows Corsa to punish those eardrums on the outside while still being able to carry on a conversation inside the car while cruising on the highway. And in my opinion, they are one of the best at doing so. But let's step away from the sound and talk a little bit more about that premium build that we mentioned at the top of this video and you are definitely getting the good stuff here from Corsa. We're talking premium 304-grade stainless steel from tip to tip including the three-inch mandrel bent tubing, unique double helix X-pipe as they call this thing. Check that out. Pretty cool stuff. Everything is gonna exit through the mufflers here that are incorporated into the system and finally out of your beautiful four-inch quad tips done up in black. Now, speaking of those quads, this is a great time to remind you all that this system will bolt directly up to your 2018 and newer Mustang without active exhaust along with any 2015 through '17 GT who may have installed that Roush rear valance or modified the rear bumper in order to fit those extra tips. Now, price point will be right around 700 bucks here. But with all that out of the way, guys, what do you say we switch gears and talk briefly about the install? Again, really easy stuff here on the '18 and newer cars. Site's just automatically gonna bump this one up to a two out of three wrenches simply because you do have to do all of your work underneath the car. But without further ado, here is that walkthrough that we promised you, in addition to a quick tool breakdown.Man: Tools required for this installation: 3/8 drive with an extension, 13 and 15-millimeter socket. Optional but extremely helpful: white lithium grease, exhaust hanger removal tool, and an impact.All right. To uninstall your factory exhaust, to start, we're going to work on these clamps and this is going to be for the 2015 and newer owners. So I have a 15-millimeter socket, I'm gonna just loosen up these clamps. All right. So, I'm just gonna slide one of them back now and then we can work on the exhaust in the back. All right. So, just behind your rear differential, you're gonna have two hangers with 13-millimeter bolts. Let's go ahead and remove those now. All right. Now, we're actually gonna pop these hangers out and off. I'm just gonna put them to the side just like that and then I'm gonna grab an extra set of hands and get this exhaust out of here. All right. So, if you're working with a lift, you might need a friend for this next step. He's going to be at the front section of the exhaust, he's gonna grab that last clamp, slide it back towards me releasing it from this front section of the exhaust. Then I'm gonna grab the tips back here and simultaneously push forward releasing it from the exhaust hangers underneath this back bumper. So, go ahead, Rob, with the clamp, then it's gonna drop down just like that and I'm going to push it out of these hangers. And it's free.All right. So, with the stock exhaust laid out on the ground, we are gonna need two things from it, those stock hangers and those stock clamps. So, we're just gonna pull these hangers off. You can use a little bit of penetrating lubrication or white lithium grease to get them off a little easier. And then we'll just pull our old clamps off and transfer them back onto the car. All right. So, what we're gonna do now is put back our factory clamps. You may have to just move them a little bit to get them to slide back on. And then after that, we're actually gonna put our adapters into them. These you definitely have to slide and twist to get them in there. And we'll get our 15-millimeter and we'll tighten those back up. You're gonna wanna make sure those are nice and tight so you don't have any exhaust gas leak. So, now we're gonna bring in our X-pipe and slide our clamps on it before we install it. And we're gonna bring it into place here, slip it over our couplers, twist it around a little bit, make sure it seats all the way down, and slide your clamps over and tighten them up. Now, we're gonna tighten these up. Same 15-millimeter socket. Slide that back a little bit.All right. So, what we're gonna do is bring up one of our mufflers. We're gonna start on the driver side. Let's get our clamp in place and then we're gonna bring up the muffler, stick on our stock hanger, slide that on. Bring this hanger up to the rear here and just insert it, slide it back as far as you can because you got to get this tailpipe into our X-pipe. So, let's do that now. Bring it back, slide it on just like that. So, let's get our clamp in place. So, let's get our hanger in place here, slide it in. Then, we can get our final adjustment when we get that other muffler on there. All right. Moving on to the passenger side muffler, again, let's slide on that clamp. So, with the clamp in place, let's go ahead and get the muffler into the hanger all the way back here. Just slides on and we can put our muffler tube onto our X-pipe, and then our hanger in place up there. So, let's go ahead and bolt our hangers back down.So, the next step we're gonna do is tighten down our mufflers. The clamp is back here, I'm gonna hold it up with one hand over here, get my impact back on that nut and get on there first. I like to clock them about 90 degrees from the ground. I'm just gonna start the clamp so it stays, bring my muffler up and tighten it up. We're gonna do that on both sides now. And to top it all off, let's add our tips. Clamp first. We're just checking for fitment right now. Now, it looks like we need to bring the muffler up just a little bit and we can accomplish that by loosening that clamp we just tightened, pushing it up and tightening it even more. Let's go ahead and get this tip tightened up. 15-millimeter socket on all these clamps.And with that, that's gonna wrap up my install of the Corsa Sport Cat-Back Exhaust with Black Tips. For all things Mustang, keep it here at

    Sport Performance Sound. GT Mustangs possess all the power, performance and impressive good looks of a modern day muscle car, now if it only had an exhaust note to match. If you're one of the GT owners that wants their Mustang's exhaust to sound as well as it performs, you need to invest in a Corsa Performance Sport Catack Exhaust System. Acoustically engineered and tuned, this Corsa Sport Cat-Back will give your coyote powered Mustang a robust, sport performance sound under acceleration and a distinct rumble at idle, all without any annoying drone while cruising. As an added bonus a Corsa Sport Cat-Back will also improve your Mustang's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

    Race Car Growl. Corsa Performance Sport Cat-Back Systems feature a very unique double helix X-Pipe that replaces the factory resonator Mid Pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.

    RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Performance proudly manufactures their Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-Pipe and two high flow, straight-through sport mufflers. The mufflers feature a pair of black chromed twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.

    Application. This Corsa Sport Cat-Back Exhaust System with Black Chromed Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018-2020 Fastback GT Mustangs that is not equipped with the Active Valve Exhaust System.

    Application Note. The 2015-2017 Model Years will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.

        Will these have any negative affect on emissions? I live in California and don't want to have to deal with that sort of thing. Also I have a 2018 GT with a Performance Package that already come with stock Quad tip exhausts so will these fit without any issues?

        • With how strict California is with emissions, it is highly recommended to contact the state to confirm before purchasing. In regards to the installation, it will be a direct bolt-on for the 2018 models that do not have the active exhaust option.

            Poor Fitment

            I do love the way it sounds, and it is made from quality materials. However, fitment is poor at the rear valance. Only purchase this if A. you don't mind it looking bad, and touching your rear valance on both sides, or B. you don't mind spending $$$ to have a good muffler shop bend/cut or otherwise customize to fit properly in the factory valance exhaust cut outs.

            Sound is amazing fitment not so much

            This is the way to go if your running long tubes. The sound is's quiet if you stay out of it and wakes up when u get on it. It has a very clean,smooth rumble all the way through the RPM range. It sounds very exotic and NASCAR rather than that old school low growl. My complaint is that the exhaust didn't fit well.. fortunately with a few cuts and welds my exhaust guys were able to move it over 5 inches and make it fit go to a skilled exhaust shop and warn them ahead of time and you will be good to go

            Go with the xtreme

            I was under the impression that I purchased the extreme kit (stupid me) only to realize it after I installed it. AM does not accept returns so just learn from my mistake. Didn't expect to pay more for a quieter exhaust.

            I love it!

            You can drive through the neighborhood without making too much noise. But as soon as you get away you can let this baby growl. Everyone loves how it looks and sounds. I had no problems with the placement.

            3 2018 GT - ParkerD Installation Time: Afternoon

            Great tone, louder when you step on it

            I’m giving this exhaust 3 stars because the tone is great! However, the fitment is just as bad as you’ve read in YouTube comment ls and reviews. It will rub on your bumper, no way around it. Also, I was shipped an exhaust with a large dent in the muffler, and dented pipes both the end of the muffler, and the x pipe which required hammering to get them to slide inside each other. The exhaust has a healthy volume for a cold start, but the idle is too quiet for my preference. When you step on the gas, the exhaust does open up and become pretty loud! I’d say if you were debating between this and the Xtreme, just go with the louder option so you don’t look back. In terms of the install, the instructions say that you can slide the stock exhaust out of the hangers, which for 2018 I was not able to do, so I had to remove the hangers completely to get everything out, and to put the new exhaust in. So install time was much longer than quoted, about 3 hours. If your on a budget and not completely sold on the Corsa tone, then you’re better off going with the Roush catback for $600 less.

            2018 Owners Beware!

            As you can see in everyone’s pictures, the figment is absolutely terrible. Even CJ Pony Parts install is still not centered, so this is not an install issue. I contacted Corsa, but they just put the blame on the shop that installed my system. Their tip design is also extremely poor for a company that’s been in the game like Corsa has. Be prepared to do some bending on your brand new $1,600 exhaust in order to get the tips not to rub on the rear valence. If I were you, I would save a few hundred bucks and buy the 15-17 system and have someone custom make you a quad tip for your 18 Mustang.

            The music this thing plays is beautiful, especially when your under an overpass and you give it a little rev :) My wife says my dog runs to the door like 3 minutes before i get home! The quality is superb, I love the black chrome tips, very stylish. My car is supercharged, and when I lay on it people jump back, but if I'm at relative low speeds, I won't wake up the neighbors. The sound in the cockpit, is just the right note, no overbearing and no drone. The quad tips just look mean, you can't go wrong! What are you waiting for.......Buy it! lol

            Wow. It's loud, I mean it's awesome so so awesome. But if you get on it, holy cow it's loud. There's no drone, it can be very very reasonable when you're just cruising which is great. If you don't want to wake up the neighbors, you won't. Absolutely fantastic, I definitely recommend it. And black tips are worth every penny.
