      Review & Installation Video

      Hey, everybody. I'm Justin with and welcome to my detailed review of the Corsa Sport Catback Exhaust System, available for your 2015 and up Fastback GT.The Corsa Sport Catback is the combination of the Touring Series Axleback here paired with the unique double helix X-pipe from Corsa. Now I'm not going to lie, the Corsa Touring Series Axleback by itself paired up with the factory resonator is pretty mild. But once you remove that resonator and replace it with the double helix X-pipe, the exhaust really comes to life as you guys just heard. In my opinion, it's going to be the perfect middle-of-the road catback. Meaning it's not going to be too aggressive and it's definitely not too mild.These systems aren't exactly cheap. In fact, the Corsa systems are some of the priciest here on the site. But with that in mind, those of you who are prepared to throw down a rather large investment on a quality catback will not be disappointed and here's why. You're getting full 304 grade stainless steel from tip to tip, 3" mandrel-bent tubing, beautiful welds, the included double helix X-pipe of course, and 4-1/2" tips. Polished is going to be your stock option. You can spend a few more dollars and opt for the black chrome, which I have on the table with me here. And last but not least we have the Touring Series mufflers.Now I know what you're thinking: "Touring series? I thought this was a Sport Catback?" Well, here's the deal, guys. Corsa has essentially created four different systems using only two mufflers. You start with the Touring Series muffler here, add in their double helix X-pipes, and you they have the Sport Catback. Start with a slightly more aggressive Sport Axleback, add in that same X-pipe, and now you have the more aggressive extreme cat-back. I know it sounds a little confusing, but you can consider yourself brought up to speed.The mufflers also include Corsa's patented RSC Technology or reflective sound cancellation, which basically means these things are going to offer plenty of bark when you're on the loud pedal but are going to be whisper quiet and drone free when you're cruising on the highway. As you guys just heard, the Corsa definitely delivers some solid tone. It is pretty aggressive. So for that reason we'll call it a four-out-of-five on my one-to-five "I don't want to wake the neighbors" scale. Now my opinion, it is the perfect cat-back. It's not too loud. It's not too quiet. The Corsa Extreme, if you are going to sheer volume, then that is going to be the cat-back for you. This styles it down a notch or two, and again it's just right in the middle. It's not going to be too crazy or obnoxious but it's still going to be heard when you're on the road.All right, guys, we talked about a lot of things so far in this video. Now let's get into the install. One of the nice things about the cat-back systems for the new S550 GTs is they require no cutting for the most part. That's certain true here with the Corsa. This is a direct bolt-on modification, it's an easy one-out-of-three wrenches on my difficulty meter, maybe an hour or two worth of your time when it's all said and done. I will say it's a little easier if you do have an extra set of hands on hand ready to help you out here. But either way, figure some basic hand tools and you'll be making noise in no time.The Corsa Sport is one of my top three favorite catbacks for the new S550 GT and here's why. It offers a tone that's going to be get you heard. It's not going to be obnoxious yet it's still livable even if and when long tube headers do get factored into the equation. If you're cool with selling a kidney to get a top quality premium exhaust system, then you're definitely going to love the Corsa Sport. Available here at

        This exhaust is fantastic. The sound is tame when idling and cruising, but when you really get on it, then it livens up and sounds amazing. Install was fairly easy, hardest part was getting the stock exhaust off, took a little over an hour. Very happy with this purchase.

        Great sound!

        My Corsa cat-back exhaust were everything I had hoped for and more. The install was easy and the sound is great on my 2016 Mustang GT! I wish I had done this a long time ago.

        Great sounding

        The Corsa Sport cat back is quiet when you need it to be and aggressive when you get on it. Got it with my car when I purchased from the dealer and couldn’t be happier with the deep sounds and thunderous backfires you get every now and then.

        Unbelievably happy!

        Like many who have reviewed I knew I was going to buy Corsa just was on the fence between Extreme and Sport. After watching video clips ad nauseum I ordered the Sport. It is the perfect exhaust for my 50 Anniversary Edition appearance package in Oxford White. One sleek and classy machine. This exhaust is LOUD! No obnoxiously so but you will get noticed. Now it sounds as fast as it is! Get the Corsa Sport. You won’t be disappointed. Only bummer was delay by UPS in delivering. It was at their local distribution center, less than 10 miles from my house, for 3 days before delivery. finally came late on Thursday night. I didn’t want to miss my installation appointment on Saturday. Happy, happy, happy!

        No drone with headers

        Took a chance with this system to eliminate the drone after installing headers with my old system. It did exactly that. Louder than I wanted but no more drone.

        Excatky what I was looking for

        I had a hard time picking the best sounding exhaust for me that was loud when I wanted, but didn't wake everyone up on cold start. This is the best exhaust for that! Cold start is definitely louder than stock, but is not obnoxious. While driving around it's pretty tame with no drone inside, but it really wakes up when you get on the throttle. I would definitely recommend this exhaust to anyone who thinks the louder systems aren't for them.

I am glad I chose the sports over the extreme the sports are not as obnoxious and they sound good have a deep growl to them! It is also a headturner/neckbreaker everywhere I go I get compliments , you won't be dissapointed with this exhaust.

        The perfect exhaust

        This exhaust is perfect. Loud when you want it tame when you don't. Endless compliments on the sound and gives the s550 the right character. American Muscle takes care of you too. When mine showed up damaged they got a new one out to me asap with minimal hassle.

        Corsa Sport

        After a lot or research, I went with sport over extreme. It was delivered the next day and with no damage to the box. Buying with AM has always been a positive experience. I haven't heard extreme live, but the sport is loud at WOT and low enough to talk in cabin in lower revs. It's pricey but a solid investment. The build quality is good, installation was fast and it changes the attitude of the car entirely. By nature, it is not obnoxious, but can get that way if that's what you want. It's nice to have the option. I have and will continue to spend my money with AM as long as the customer service quality stays the way it is, which is excellent.

      Would you recommend getting new exhaust gaskets for this system? It doesn't look like it comes with them.

      • It would only be necessary if what you're working with currently prior to the purchase of this kit would need replacing. Otherwise it would not be necessary.

      will this give me an increase in hp?

      Will this bolt up to both stock shorty headers and Corsa long tube headers?

      • Yes, the cat back can work with long tube or short tube applications.
