The perfect exhaust

Extremely well made and a perfect fit. Zero drone and it sounds great. I've had many exhausts on many cars and this is one of the nicest built systems i've ever seen.

wil this fit a 2014 v6 if i have a gt500 rear valance


  • The piping on the Corsa Sport Axle-Back Exhaust - Quad Tips (13-14 GT500) is a half an inch larger in diameter than your current piping, so it won't bolt up without modifications. Otherwise, the valance will allow it to fit!

    Corsa Sport Axle Backs

    These are excellent mufflers that meet or exceed all advertisement. They sound very much like stock at idle and around drone. They explode with muscle car sound at WOT. I felt the cans were a bit bigger and lower than stock. Corsa advised to paint the back plate of the muffler with flat black high temp paint. This made the muffler housing disappear under the valance and really made the awesome O-Sized chrome tips really pop !

    Corsa sport axle back on a 2013 GT500

    Looks and sounds really good. It could be a little bit louder though. Install is about hour and a half. Even though I keep scratching my head how am I going to make this a little louder, i'm happy with the product and would recommend it.

    Corsa Sport 14321 Exhaust sounds has a nice deep tone. It sounds good at an idle and sounds great when accelerating and at WOT. At cruising speed there is no drone inside the car which is one reason I bought the Corsa. It feels like it freed up the exhaust and has more power than the stock exhaust. The polished tips look great coming out of the back of the car. Looks great, sounds great and has a little extra win!

    Wicked look sound

    I installed these myself with the help of one other - there are a plethora of helpful videos online to do this comfortably in your driveway. Cutting your bumper to fit the GT500 rear valence is a bit nerve racking, but TRUST me. DO IT. I used a dremel tool to cut the bumper along the lines Ford so graciously provided. Hooking the mufflers into the rubber hangers takes some SERIOUS muscle. It is a bit tricky to get the quad tips to be even on both sides (mine were uneven until I took it to the shop for my X pipe install). Now when the install was complete and I first turned the key to my ignition, I literally almost teared up. The sound these mufflers make is the most beautifully violent noise I've ever heard. Such a deep, aggressive rumble and at about 2k-3k RPMs it sounds MEAN. However, the only drawback is that anything over 3k sounds hollow. When I paired it with an O/R X pipe, it screams like a cross between a Ferrari and a demon. The best thing about this product? It sets your car apart from the horde of rival 'Stang owners, and that's all that matters!

    Installed this on my 2013 GT along with the GT500 rear valance and its perfect. Yea its expensive but worth every cent. It's not loud and obnoxious like some exhaust systems out there, health sound while cruising and regular driving but definitely possible to make your presence known if you want. By far some of the best money I've spent on my car thusfar.

    Sounds even better!

    Installing this exhaust was a peice of cake. One tip though, I didn't do it, but loosening up the next set of pipes will give you much better clearance. The view and sound after install is awesome especially with the staggered slash cut tips.

    Not Loud, Deep but Almost stock like

    Great quality mufflers, but when I first installed them they seemed quieter than the stock mufflers. After awhile they warmed up and have a good deep sound to them but I wouldn't say they are louder than stock at all. The matched cut tips to look stock is what really sold me but I kinda wish they were louder. Pairing with LT's and high flow cats later on but if they remain this tame after that I will be looking for something more aggressive in sound. I recommend these for quality but sound is just a preference thing to the beholder.

    Awesome Look and Sound

    These mufflers are a little pricey but the look, sound and quality make them well worth the price. I installed these along with a GT500 rear valance on my 2013 GT, and they transformed the rear of my car from run-of-the-mill to supercar. The sound is powerful and loud when you are on the throttle but "gentle giant" when cruising. I hesitated spending this much, but now that they are installed, I am glad I bought them. Absolutely awesome!

    I'm so sad I didn't find these sooner.

    Now normally I'm not one to praise a company, or even write anything that even resembles a review, however, I'm hoping someone at Corsa comes across this. JUST purchased and Installed the Sport GT500 Quad Tip exhaust on my 13' GT/CS after pulling off my Borla ATAK's...I've never been more please with an exhaust in my entire life. Not only is it absolutely gorgeous (and not just the tips, the chambers are stainless steel and chromed as well) but the sound is unparalleled. My ATAK's were loud, race car loud, and at WOT it sounded great, but while driving normally anything over 2k RPM made it unbearably loud within the cabin. The Sport's from the get go, sound perfect, you can drive normally, upwards of 3,500 RPM and not be deafened by the exhaust note, however, when you step on it...oh boy when you step on it, the beast is released. I noticed that the Corsa also has a deeper tone to it, much more muscular sounding than the Borla which had a higher pitch to it. If you are considering anything other than Corsa, stop considering, Just do it. They say you get what you pay for...They couldn't be more right in Corsa's case. TLDR : Corsa is the absolute bomb and I'm so upset I didn't come across them sooner.

    Best sound out there!

    The price was worth it on this axle back setup. Corsa came up with an exhaust that doesn't make it sound like a farm truck that all the other competitor mufflers have achieved. The sound is just pure greatness! Highly recommend these. No drone at all either inside.

    A beautiful rumble like no other.

    I am the proud owner of a 2014 GT, I had this exhaust installed with the GT500 rear valance and is paired with the Flowmaster X pipe. It really transforms the rear of the car into something beautiful and aggressive. Everyone I know has Flowmasters or BBKs, which are great, but if I wanted my car to sound like everyone elses I'd have left it stock. I guess what I'm trying to say is that this exhaust is diffrent than most. It caters to a select few that are willing to blow two to three times the amount of money than some more common axle back systems to have that uniqueness. The sonud is, as my girlfriend put it, "a refined beast." At start up and idle the beast is quiet. It slumbers with a deep and foreboding rumble. When the gas is pressed however, the beast awakens with a majestic roar unlike any other car on the road. There is no drone on my setup and everything has been fantastic. I recommend this product highly and I can assure you a I was a skeptic before, that you will not be dissapointed.

    Expensive but you get what you pay for

    These things are really a work of art. The welds, the finish, the laser cut tips. This is easily the best looking exhaust on the market IMO. Tone is quiet and tame at idle, at 2k it starts to purr, anything 3k and it SINGS. I couldnt ask for a better tone, it really is perfect in my opinion. Pick these up, you wont regret it! Only problem I had one the right muffler does not come out of the valence as far as the Left one. Will need to take it to a muffler shop as this type of adjustment is out of my skillset.

    Significant improvement over stock!

    This looks amazing with paired with the GT500 lower valence. The finish and welds on these are perfect and appear to be of high quality. The exhaust note is very aggressive sounding. It has more of a deep rumbling growl, definitely not raspy sounding. It is almost stock quiet at idle but as soon as you hit the throttle it really growls. Very pleased with this purchase.

    Wow! Awesome! What a difference!

    This exhaust system is heads and tails above the stock dual exhaust my 2014 GT/CS came with. It growls and looks mean from the back. It is exactly the sound I was looking for and no drone on the highway. People turn their heads when I drive by! I would recommend these to anyone who wants to make a tiger out our your GT. We ordered them - they came when we were told they would. They were well packaged so there would be no damage. We also ordered the GT500 Valance to match which fits perfectly. American Muscle Rocks!

    Top quality product!

    After researching the different makes of axel back mufflers for my 2014 Shelby GT500, I decided on the Corsa sport quad tip exhaust. I was expecting a high quality product and received a product that exceeded my expectations! Installation went very well...take your time and follow the instructions. This put the finishing touch on the looks and sound that I wanted. Money WELL spent. Highly recommend this exhaust.
