    Sport Performance Sound. GT Mustangs possess all the power, performance and impressive good looks of a modern day muscle car, now if it only had an exhaust note to match. If you're one of the GT owners that wants their Mustang's exhaust to sound as well as it performs, you need to invest in a Corsa Performance Sport Catack Exhaust System. Acoustically engineered and tuned, this Corsa Sport Cat-Back will give your coyote powered Mustang a robust, sport performance sound under acceleration and a distinct rumble at idle, all without any annoying drone while cruising. As an added bonus a Corsa Sport Cat-Back will also improve your Mustang's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

    Race Car Growl. Corsa Performance Sport Cat-Back Systems feature a very unique double helix X-Pipe that replaces the factory resonator Mid Pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.

    RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Performance proudly manufactures their Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-Pipe and two high flow, straight-through sport mufflers. The mufflers feature a pair of black chromed twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.

    Application. This Corsa Sport Cat-Back Exhaust System with Black Chromed Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018-2019 Fastback GT Mustangs that is not equipped with the Active Valve Exhaust System.

    Application Note. The 2015-2017 Model Years will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.

    I have a 2015 gt convertible does it fit because I saw the other corsa exhaust has fastback and convertible

    I have a 2017 PP GT base model....if I get the MP Concepts GT350 style rear diffuser...will it be compatible?

    • The Corsa Sport 3 in. Cat-Back Exhaust will fit 2017 Mustang GTs equipped with the Premium Package, and a Roush rear valance.

    Will these have any negative affect on emissions? I live in California and don't want to have to deal with that sort of thing. Also I have a 2018 GT with a Performance Package that already come with stock Quad tip exhausts so will these fit without any issues?

    • With how strict California is with emissions, it is highly recommended to contact the state to confirm before purchasing. In regards to the installation, it will be a direct bolt-on for the 2018 models that do not have the active exhaust option.

    Do you expect this exhaust to fit the 2018 Mustang GT when it comes out in the fall?

    • Hello! Unfortunately we do not have enough information quite yet on the 2018 Mustang GT's to answer that question! I would check again when the car is released.

    Will this fit together with a custom GT350 valance I have installed on my mustang?

    • If you have a GT350 rear valance that has the ability to support a quad tip exhaust, than this Corsa Sport 3 in. Cat-Back Exhaust - Fastback - Black Quad Tips (15-17 GT) should be able to fit. Just make sure that you have the correct measurements for your custom valance!

      I love it!

      You can drive through the neighborhood without making too much noise. But as soon as you get away you can let this baby growl. Everyone loves how it looks and sounds. I had no problems with the placement.

      Great tone, louder when you step on it

      I’m giving this exhaust 3 stars because the tone is great! However, the fitment is just as bad as you’ve read in YouTube comment ls and reviews. It will rub on your bumper, no way around it. Also, I was shipped an exhaust with a large dent in the muffler, and dented pipes both the end of the muffler, and the x pipe which required hammering to get them to slide inside each other. The exhaust has a healthy volume for a cold start, but the idle is too quiet for my preference. When you step on the gas, the exhaust does open up and become pretty loud! I’d say if you were debating between this and the Xtreme, just go with the louder option so you don’t look back. In terms of the install, the instructions say that you can slide the stock exhaust out of the hangers, which for 2018 I was not able to do, so I had to remove the hangers completely to get everything out, and to put the new exhaust in. So install time was much longer than quoted, about 3 hours. If your on a budget and not completely sold on the Corsa tone, then you’re better off going with the Roush catback for $600 less.

      2018 Owners Beware!

      As you can see in everyone’s pictures, the figment is absolutely terrible. Even CJ Pony Parts install is still not centered, so this is not an install issue. I contacted Corsa, but they just put the blame on the shop that installed my system. Their tip design is also extremely poor for a company that’s been in the game like Corsa has. Be prepared to do some bending on your brand new $1,600 exhaust in order to get the tips not to rub on the rear valence. If I were you, I would save a few hundred bucks and buy the 15-17 system and have someone custom make you a quad tip for your 18 Mustang.

      I haven't been able to drive the car due to 24 inches of snow over the weekend but startup and rev sounds amazing tips do not fit perfect that's why I'm giving it a 4. Especially for a $1665 exhaust....

      The music this thing plays is beautiful, especially when your under an overpass and you give it a little rev :) My wife says my dog runs to the door like 3 minutes before i get home! The quality is superb, I love the black chrome tips, very stylish. My car is supercharged, and when I lay on it people jump back, but if I'm at relative low speeds, I won't wake up the neighbors. The sound in the cockpit, is just the right note, no overbearing and no drone. The quad tips just look mean, you can't go wrong! What are you waiting for.......Buy it! lol

      Awesome product

      Great for those who want a loud and aggressive V8 sound, but also need the quiet low rumble in the HOA neighborhood.

      2015 Mustang GT Corsa Sport

      Wow. It's loud, I mean it's awesome so so awesome. But if you get on it, holy cow it's loud. There's no drone, it can be very very reasonable when you're just cruising which is great. If you don't want to wake up the neighbors, you won't. Absolutely fantastic, I definitely recommend it. And black tips are worth every penny.
