Review & Install Video

Hey, everybody. I'm Justin with AmericanMuscle.com 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 AmericanMuscle.com. 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 AmericanMuscle.com.

Xtreme Aggressive Sound. 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. A Corsa Xtreme Cat-Back will greatly improve your pony's exhaust flow for an increase in overall performance.

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 mirror polished 4.5" Pro-Series tips. This 3" catback also includes step down flanges so it can be installed with the factory 2.5" exhaust.

Application. This Corsa Performance Xtreme 3.0" Cat-Back exhaust system is designed as a direct bolt on replacement for all 2015-2017 GT Fastback Mustangs equipped with the Coyote 5.0L V8 engine. Please choose from Fastback or Convertible in the options above.

With this exhaust is it still possible to slip out of the neighborhood at 4am without waking the neighbors? I go to work very early in the morning and a small part of me doesn't want to wake the entire neighborhood. I have read many reviews saying its all in your right foot but from what I have seen on YouTube that is only true in 6th.

ChrisC

  • The Corsa Xtreme Cat-Back Exhaust features a deep aggressive sound. You will hear a nice rumble when idling and cruising. It will also be loud and aggressive when you are at WOT. If you are just coasting through you neighborhood, it should not be to loud. But be aware, it will be louder than stock.

Are the muffler sections that come on this exhaust identical to the Corsa axle back system? I want to lower the sound volume. Can I purchase the touring axle back system to replace the mufflers on this system?

will this setup pass inspection and emissions in texas?

Angel

  • Hey Angel, This set up should pass all emissions restrictions, the emissions usually only has to deal with the catalytic converters and they are located on the headers of your S550. But each state is different in terms of inspection and emissions, though generally these won't effect inspection or emissions.

    Corsa Xtremes On A Daily Driver: A Review

    Okay, so this is as honest a review as I can give. Like many of you probably did, I watched (literally) hours of YouTube footage when trying to decide on the best exhaust for my 2017 GT. The Xtremes immediately stuck out to me as sounding especially good, but I was also worried about the volume since my Mustang is my daily. Now that I have them, here are my thoughts. Exhaust note: absolutely incredible. Seriously. The tone on these in person vs YouTube videos does not even remotely compare. In addition to the general sound (deep growl at low RPMs, screaming at high ones) there are so many subtle noises the videos don't capture. I've heard other reviewers describe it as the sound of exhaust gases racing through the double X and that's probably the most accurate way to put it. They crackle, pop, growl, and make an incredible variety of noises. The exhaust note is better than I could have ever hoped for. I think one reason it's so good is because unlike other exhaust notes for the S550s, this system doesn't try to stay deep throughout the whole RPM band. The Coyote engine is no longer the deep, growling muscle car engine of the old 5.0s. It loves to open up and rev and this system complements that perfectly. Honestly, it reminds me of the old 4-valve 4.6s (a la the 03/04 Mach 1). Volume: as others have said, the reason this system is so good is because it's loud when you want it to be and fairly reserved when you don't. Make no mistake: it's basically always louder than stock, but the stock exhaust is also *very* quiet. The cold starts *are* quite loud - if you live right next to someone, or maybe in an apartment right in front of someone's window, this may be an issue for you. If you have even a moderate amount of space between you and your neighbors, you'll be fine. Cruising through the neighborhood at 3AM? Just stay in lower RPMs and you're fine, you won't be waking anyone up. However, when you're on it, it *does* absolutely scream. These are very loud *when you want them to be* I was very nervous that they would just be loud all the time, and while they are *audible* all the time, they aren't melting-your-face-off loud unless you're driving in a way that would reflect that. So, is this system too loud for you? That depends on where you live, how and where you're driving, etc. In general, my answer would be no. But if you live right on top of someone, it may be. Just depends on your situation. I've had no issues here. Install: fairly straight-forward. Either get a lift or about three sets of hands or you'll probably be working longer than you think. Takes some effort to get everything lined up but overall it's nothing too terrible and can be done in a couple hours, maybe a little more. Cost: well, these aren't cheap. What they are, however, is 100 worth the cost. The tone is intoxicating, the volume is insane when you want, docile when you don't, the build quality is fantastic, and most importantly: no drone. Like, none at all. Seriously. You get what you pay for. If you want something that doesn't sound awful on the highway and isn't constantly destroying your hearing, this is what you need. Corsa delivers, end of story. Overall impressions: I am absolutely in love with this exhaust. Don't be scared of some of these reviews that say they're "INSANELY LOUD!!!" They *can* be, but they aren't all the time. This is the best exhaust I have ever heard on a 2015 Mustang, easily. If you're on the fence about these and have the money and your living/driving situation allows for it, get them. Stop thinking about it. Just go for it, I promise you won't be disappointed.

    Video doesn't even compare!!!

    I was debating on this exhaust and the atak which I'm sure is still good and I'm glad I went with this one. Absolutely no drone, and when you gun it, the mustang just sounds menacing!!! The install took me about two hours, had take off the stock exhaust system with jack stands and no assistance plus I took my time making sure every bolt was snug. Perfect fit, quick delivery, awesome sound. Almost sounds like the mustang has long tubes with this exhaust. The videos I've seen everywhere really don't compare to the real deal. You get what you pay for don't hesitate. Hope this helps!!

    Perfect exhaust

    Bought this exhaust and every time I start her up its music to my ears. I don't know why some people say it's too loud because in the cabin I can barely hear it, there is absolutely no drone. On the outside she screams and is a pleasure to listen to with the windows down. Overall I've had 3 Stangs and this exhaust is by far the best I've owned out of the 3 systems I've had on my others. Don't hesitate the price is well worth the sound and quality.

    Everything I wanted and more!

    As a lot of people have noted this exhaust has an exotic note to it. To me it sounds like you can hear the exhaust gases ricochet off the double helix x-pipe as it rushes, rolls, and rumbles out the rear! It sounds awesome making me grin ear to ear every time I start it and drive, and the best part of it all is that it can be as loud or quiet as you want. When giving it gas it even at the lower rpms it rumbles, accelerating north of 3k rpms and it will turn heads (in a good way), and letting off the gas in the higher rpm range results in a lovely tune as the engine brakes. As I mentioned earlier it can also be very quiet, I mean drive past your neighbors' houses in the country side without waking anyone up quiet. In addition to all that goodness, there is no drone what so ever, on the highway with a 2016 gt manual PP I hear more road noise than exhaust when I'm coasting or not giving it gas. The performance enhancement is noticeable by itself (I have not yet installed the CIA Tune I bought to go along with it), it climbs the rpms so much quicker and breaths better as a result of less back pressure. The Install was easy since I was fortunate to have a two-post lift to work with. The only problem I had was the reduction couplers, which I needed to grind and bevel a little for a better fit with the 2.5" factory catted headers. Otherwise seamless install, I would recommend exhaust paste made by permatex just for a little peace of mind (It does not require it). Finally make sure to avoid getting the anti-seize on your exhaust when putting it on the clamp bolts because it will tarnish it.

    Had this catback for over a year now...

    In my opinion, this is the best sounding exhaust I've heard for the mustang. The way the coyote is designed, it's not supposed to have a deep tone/growl, it's a 203 CI modern powerhouse. The Corsa Xtreme Catback is a perfect compliment to that. If you are taking it easy or highway cruising, it sounds almost silent.... BUT when you get on it, it is LOUD, REALLY LOUD, and it has that raspy exotic sound that is completely unique from any other Mustang exhaust I've heard. I recommend this exhaust 100. If I ever get another Mustang I will be getting this exhaust again. The black tips look amazing too btw.

    You get what you pay for!

    So being that this was one of the most expensive exhaust systems I got exactly what I wanted. A loud menacing beast when I put my foot down. But an unnoticeable purr when I'm in 6th gear cruising down the highway. The install was pretty straight forward. Only problem I had was with removing the factory clamps. But that was a misunderstanding on my part. Everything in the box fit together and lined up perfect. Took about 45 minutes from start to finish. The only complaint I got about this exhaust is from my neighbor who has threatened to call the police! But screw him!

    After I got my product on time I went in to install it. It took about 30 min not even an hour just to install it. When I started my car after the installation I was shock from the tone and volume this exhausted has. It's just really loud. Its loud by watching it by vídeo but even louder watching it in person. It really is worth the money and the timé waiting for to arrive. Thank You American Muscle for such great Service!

    I love this exhaust. It sounds exotic and super aggressive. My 2015 GT sounds so much better now. It has a deep rumble when idle and as you rip through each gear, it really opens up the engine. Excellent product for an excellent price. I'd highly recommend this exhaust for your 5.0 .

    Oh my goodness.....

    Hands down, the best sounding exhaust for the 15 GT. Installation took me and my friend about 45 min on a lift. Everything fits great. You can feel the quality, amazing. Then the 4.5" tips look fantastic and pretty much fills in. But once I turned it on.... Oh man, such a beautiful sound. Cold start is super loud and made my neighbor come out haha. Driving it around shifting at 3k rpm sounds good, and yes ZERO DRONE! But once you get on it, it sounds like it's shredding the streets. I've had people roll up their windows and tell me it's too loud...perfect :). Overall this is the best bang for your buck, and you can find it right here on American muscle, they'll get it to you ASAP. I would recommend everyone get this exhaust for their 2015 GT!

If you keep your foot out of it then it's nice and quite but when you get on it it really wakes up. This was a shop install. Took 2 hours at $75 an hour. Took a little bit to get the tips lined up perfect but it came out great.

    Corsa xtreme...extremely worth it!

    So before I bought this exhaust I debated for about two weeks between the frpp borla sport catback and the corsa xtreme catback. I watch tons of YouTube videos. Well I went with corsa. They were a little higher in price but let me tell you. ITS WORTH IT. My buddy has a 2015 get as well and he went with the frpp borla shortly after I reviewed my corsa. The corsa blows his out the water sound wise. And believe it or not. No drone what so ever unless you're laying your foot in the gas. Over I love the exhaust and couldn't be happier with it!

    Simple review

    Im barely going to hit 100 miles with them on. But, like what most people say... its loud from cold start, barely here at highway speed unless you punch it. They're fun to have and definitely make driving that much more enjoyable. Turning on my car at 5am to go to work is the only thing that makes me wonder if the neighbours get annoyed with it at all.
