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.

    Amazing

    This exhaust is great!! Perfect fit. No cutting no bending, nothing. Lines right up with the stock hangers and everything. The sound is phenomenal!! It’s quite when you need it to be and when you want to open her up, that roar is right there. High quality, amazing sound. Definitely worth the money. If you have a lift the install is super easy and straight forward. 1.5hr start to finish.

    Worth the money

    Exhaust is exactly as described. Lot of volume when you get on it. Limited cab noise when cruising down the highway. Would definitely recommend if you’re looking for great sound without earplugs.

    Corsa Extreme Exhaust

    Installation was about a hour long, could be shorter with power tools and 2 people. Corsa triple packages the exhaust so no damage is done during delivery. Car sounds amazing. Aggressive tone during normal driving, anything after 3k rpm is like waking up the dead :). Can't wait for headers and gt350 intake manifold

    Not as loud as you think

    I just got my corsa Xtreme cat back system and I must say the no drone on the inside.. absolutely flawless. No drone, nice and mellow inside. Great job. Outside rumble though, could be louder. After all the reviews and YouTube videos I’ve seen. Everyone always said it’s loud, and the neighbors will hate you. Well I had a muffler delete with a standard x pipe and I’m positive that was louder that my corsa. More drone yes but louder when I drive by YES. So while this system is good so far. Trust me it’s not as loud as others say it is. It’s actuall fairly mellow on low rpm.

    WOW

    You won't be disappointed. Loud and aggressive it is. But no drone as advertised when cruising. Can be pretty quiet when you want it to be and loud as heck when gas it. That's why I personally think this is the best performance exhaust on the market. It's the priciest but it's worth it.

    Exactly what I expected!

    Very loud upon cold start up but settles down nicely once the RPMs drop off. Very tame cruising but the moment you give it the beans it absolutely screams. For and finish was top notch as you'd expect for the price. No regrets whatsoever about this system.

    Corsa xtreme happiness

    Talk about satisfaction! You really will not regret getting this exhaust! I've been contemplating on an exhaust and at first I was a bit hesitant about the xtreme but I said, "wth let's do it". Best decision ever, its loud, aggressive and at high gears keeps a low purr sound. Let the world know how much power is under that hood. Your stock setup has nothing on this.

    Neighbor Hater

    First off Cold starts are brutally loud, so if you are close to your neighbors then these might change that relationship lol. Anyway I do like the growl and the install is super easy just connect and clamp then tighten. This is the best Catback system period. Don't settle, If these are to expensive save your money till you have enough to buy. Period!!!

    Wow

    First exhaust I’ve ever had on my 2016 GT and I love it. Sounds absolutely amazing and LOUD when you step on it, but quiet and no drone when cruising...just as everyone else has said. Cold starts sound soooo good. I think I almost gave my neighbor whiplash on the first cold start in my garage. It will definitely turn some heads. Super easy install..can just be a pain to get everything just so when you’re done. Having a couple extra hands will help with that.

    Love the sound

    I love the way it wakes the car up when you give it a little but no drone while cruising. I wanted black tips but not for 150$ so I bought black bbq paint for 8$ and painted my self and it’s been 6 months and still looks good and sounds like a monster. Corsa is the only way to go in my opinion I love these pipes
