    Review & Install Video

    Hey, everybody. I'm Justin with and this is going to be my review of the Corsa Xtreme Catback Exhaust System available for your 2015 and up Mustang GT Fastback in your choice of either a black or polished tip. Corsa actually got their start making high-end exhaust systems for marine and boat use back in the '80s. Their systems were such a hit that they figured they'd try the automotive world and, as a result, the Corsa Exhaust Systems have been a favorite with many car owners ever since. All right, with that out of the way, let's get down to business. Now the Corsa Xtreme is going to be for the S550 owner out there who is looking for quite possibly one of the loudest Catbacks available on the market today.Now, as you guys just heard, this thing certainly delivers in the tone and volume department and so for that reason alone this is a strong five out of five on the one-to-five, or one-to-wake the neighbors scale and it's going to be awesome. Now it's going to be a little bit more high-pitched, too. A lot of you guys have actually pointed out on the reviews that it has almost an exotic kind of sound to it and that's largely in part here thanks to the unique double helix, or double X pipe design as Corsa calls it, unique to the Corsa systems, working in conjunction here with these straight through mufflers and it's going to give you that higher pitch tone. A little bit more raspy, of course. Now if you're looking for the volume but maybe you want something a little deeper toned, may I make the suggestion of checking out the Borla S-type or the Borla Stinger. It's still going to offer plenty of volume, but it's going to have a little deeper tone to it. Getting back to the Corsa Xtreme here, now I like to refer to the Xtreme as the Jekyll and Hyde of the exhaust world because, yes, it can be crazy loud and melt faces when you're on the pedal, but it can also be whisper quiet when you're lugging around town or cruising on the highway. And that's always been one of the big pros with the Corsa system. A lot of companies say that their exhausts don't drone but Corsa defines zero drone. It's the benchmark. Now I've actually had a Corsa Xtreme on my '14 before, one of my favorite systems for the reasons I just mentioned. Again, super loud when you want it to be but super quiet when you want it to be. A lot of this is due to the tech and the design in the systems themselves. Corsa uses the patented RSC technology, or reflective sound cancellation which, again, is going to give you the best of both worlds.That RSC technology in addition to the killer quality Corsa is always known for is certainly going to push this Catback into the premium or high-dollar price range here. But, as the old cliché goes, "You get what you pay for." Looking at the build quality here, guys, full 304-grade stainless steel starting with the Xtreme mufflers. Again, straight through by design. We're also looking at three-inch mandrel-bent tubing throughout. Again, full stainless. The double helix unique X-pipe here with the Corsa system, it is going to help give you that raspy note as you guys heard a little earlier. And, finally, we have the four-and-a-half inch Pro Series slash-cut tips available in either a polished finish, which is going to be the stock option here when you order the system or, for an extra 100 bones, you can opt for the black chrome finish. Now normally, guys, I would say paying an extra $100 for tips might be a little crazy but the black chrome is totally baller here with the Corsa system and it's actually going to discolor nicely as it goes through a few heat cycles.Getting to the install here at the Corsa Xtreme, really not that bad thanks to the independent rear suspension. So figure removing the factory system and installing the new Corsa in its place really isn't going to be that big of a deal. For that reason alone, we're going to give it a strong one out of three wrenches on the difficulty meter. Again, not hard, just a little cumbersome especially when you're dealing with this larger X-pipe here. So if you have an extra set of hands, maybe attached to a friend or relative to help you out, it's certainly going to make life a whole lot easier. Figure about an hour or two before you're making noise here with this system and, again, basic hand tools, jack, jack-stands, or a set of ramps and you should be good to go. So if you're on the search for both volume and quality from your new GT's exhaust, I can assure you you're going to get plenty of both here with the Corsa Xtreme. While pricey, it continues to be one of the favorites on Don't take my word for it, read up on some of the customer reviews and be sure to check out a Corsa system for your ride right here at

Corsa Performance Xtreme Cat-Back systems are acoustically styled and engineered to give your 5.0L Coyote powered S550 Mustang a throaty aggressive sound under acceleration and a deep growl at idle all without annoying interior cabin drone.

    Race Car Growl. The included Corsa X-Pipe for the S550 GT Mustang's not only helps improve exhaust flow for an increase in power, but with its modern double helix "X" crossover design it also adds a crisp raspy, race car growl to the sound of your Pony's exhaust.

    RSC™ Technology. Corsa designs their mufflers using their own patented Reflective Sound Cancellation® Technology (RSC™) to give your Mustang an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Cat-Back systems are manufactured in the USA from 3.0" diameter premium grade 304 stainless steel tubing for a improved exhaust flow and a perfect fit. The system includes a double helix X-pipe and features two straight-through mufflers that end with black chrome 4.5" Pro-Series tips. This 3" Cat-Back also includes step down flanges so it can be installed with the stock 2.5" exhaust.

        Hi, My current setup is a resonator delete, X pipe and roush axle back. Will this be a problem when installing the corsa extreme? Thanks

        • The Corsa Xtreme Cat-Back Exhaust will require the removal of the X-pipe to be installed but will work yes.

        I've got a '17 GT premium convertible, will this system fit WITHOUT removing some structural support? I've seen some systems that require removal of structural support to make it fit.

        • The convertible option for the Corsa Xtreme Cat-Back Exhaust will fit your 17 GT Convertible without having to remove the added support bracing.

            Unreal exhaust note

            Absolutely love the sound of these. Best described as loud and crisp. They really tend to wake up around 3,000 RPM. Cold starts are pretty obnoxious and may bother neighbors. To be honest, it's not as bad as you think with startups. Unless its 5:00 A.M, should be fine. When cruising, you get a snarling rumble. WOT absolutely screams. You sometimes get crackles and pops on downshifts. Took about an hour to install. Some fitments were a little too tight and was a pain to work through but the build quality was stellar. Would recommend. A

            Install, super easy. Just unbolt the stock exhaust and throw it right up in there. Couldn't be easier. If you want to let your neighbors know, that you're leaving. This is the exhaust for you! I find myself listening to this exhaust note everyday as I got through the gears. Then I look down at the speedometer and I'm glad there aren't any cops around lol. Couldn't be happier with this exhaust!

            Spend the money...

            Videos on YouTube dont do this system justice. Install is super easy even with hand tools and jackstands. It can be relatively quiet when you want, but give it the beans and it screams! Only fitment issue was getting the tips to line up, which is an easy fix by just bending the hangers bit by bit until the tips are where you want them. Recommended you get a buddy to help you install. I tried using rhino ramps but they didn't get the car high enough off the ground. Ended up just using jack stands my buddy brought. Took us a little over an hour to install without air tools and a lift.
