      Video Review & Installation

      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
