    Im Running GT500 Mufflers on my 13 GT. But they are a bit 2 quiet for me. Are the Sport louder or the same as the GT500 Muffler? Greetings from Switzerland :)

    • The Corsa Sport Mufflers are great choice! I personally like them due to their lower volume low RPMs to help reduce drone. But as soon as those RPMs start climbing these mufflers start to scream! I think these would be a great upgrade for you! Cheers from the U.S.A!

    Difference between these and the Extreme corsa

    • The Corsa Sport Axle-Back Exhaust will use less aggressive mufflers than the Corsa Extreme versions, allowing it to offer quieter, deeper exhaust notes at the expense of the louder, more raspy note of the Extreme mufflers. These will still be an aggressive and loud muffler, just not to the same extent as the extreme version.

      Review from Corsa Sport Axle-Back Exhaust - Black Tips (11-14 GT; 12-13 BOSS 302)

      Great exhaust!

      I had the roush axle back exhaust installed on my car, then upgraded to a high flow catted x pipe and it was nascar loud. After doing countless hours of research and watching videos online I decided to go with these mufflers. The build quality is absolutely amazing! Very high quality steel, the exhaust tips are a thing of beauty and form to fit reflecting body lines in the bumper as well as the rear valence. The black chrome tips are amazing as well, the finish is something you don’t see very often. As far as the sound goes, drone? No. None and I mean none. When you are just cruising around it has a burply rumble that won’t alarm the neighbors but as soon as you get into it these mufflers open up and are loud! It’s as good as it gets without having electronic cut off valves in the exhaust. If you are looking for the best quality for your mustang and need it to be quieter around the development to avoid those noise complaints but still want to hear that loud muscle car V8 when you are out on a spirited drive, look no further.

      Everything I wanted and more

      This exhaust sounds amazing, if not the best. In my opinion it is the best hands down, it produces a beautiful sound throughout every RPM and sounds rather quiet when you want it to be. And the best part is.... NO DRONE. I wish I bought this to start with.

      Review from Corsa Sport Axle-Back Exhaust - Black Tips (11-14 GT; 12-13 BOSS 302)

      Bought by Accident

      I actually meant to buy the Corsa Xtremes and didn’t even realize til AM told me to review my Corsa Sports! Had my resonators removed while installing these, and it is quiet when you want and a deep loud growl when you want. Couldn’t imagine the Xtremes sounding much better! Black tips look sleek with the murdered out look I’m going for.

      Review from Corsa Sport Axle-Back Exhaust - Black Tips (11-14 GT; 12-13 BOSS 302)

      Best exhaust ever

      Just put on my new Corsa Sport mufflers with the black tips on my 2013 GT/CS. They sound and look great!! Installed them with a Pypes after-cat x-pipe which gives them a great sporty tone. Finish and fit was perfect. They are the perfect level of loud for my taste. Not much louder than the stock mufflers at idle but will let you know they're there when you get on the gas. Definitely would buy again. Great product and great service from American Muscle.

      These are quiet when they need to be, but loud when you want them to be. The tips look great as well, filling the rear valance up nicely.

      Couldn't be happier

      My wife and I wanted an exhaust that would turn heads, let everyone know it wasn't stock, but not obnoxius. The Corsa sport exhaust is exactly what we wanted. We couldn't be happier.

      5 Stars for Corsa

      Quality and fitment are exactly what you would expect from a top tier product with a lifetime warranty. Installation was straight foward and requires a minimal amount of tools. Sound department: Corsa's RSC tech lives up to its claims. It's perfectly quiet enough to carry a conversation or listen to the radio while at cruise with a nice undertone and won't rattle your door panels apart. Slow cruising offers enough tone and volume to turn plenty of heads. And it's ready whenever you are to poke the loud pedal and snap necks. I've experienced plenty of undesirable exhaust noises that are either too quiet or over the top, over priced or substandard in general. Overall, I am very impressed with the quality and fitment as well as the sound and I would have no issues recomending this company to a friend. Worth the cost.

      WORTH THE MONEY - NOTHING COMPARES

      Before getting these mufflers I went through a ton of other brands, only to find drone and ugly sounds. after getting fed up with it, I went back to stock and then purchased these. SOUND: The exhaust note is simply incredible. I can honestly say that my mustang has a more fine, expensive sounding exhaust note than most exotic cars. Sounds silly, but it's true. No other exhaust Ive heard comes close to the sound of Corsa. see volume later in review. while decelerating in gear, the mufflers create a kind of rolling thunder sound that's almost like bubbling or popping, but not in a bad way... in a great way. under acceleration the exhaust keeps the same deep deep tone,, and goes insane above 5Krpm. if you pair this with an intake, you'll really hear it. above 5000 it sounds as if I just hit a nitrous button, it's insane, in the best way. LOOKS: Gorgeous tips. solid stainless steel construction, perfect welds, rings like a titanium aircraft turbine when tapped. incredible quality all around. FIT: You will have to unbolt (just so they can swivel) the over-axles from the midpipe to make your life easier here. Getting the old mufflers off and these on requires some serious creativity and patience. Tips are to grease the hangars on both sets to ease uninstalling and installing, and when mounting the Corsas, seems like the forward inboard hangars should be slipped on first. be patient, it's like solving a puzzle trying to work these on or off. VOLUME: started it up, cold start, thought it was stock haha. very quiet start up and idle, barely louder than stock, but with a muuch different sound. Gorgeous tone. again, idle is quiet. Not too bubbly like Roush, but very "5.0"ish. under normal acceleration you can definitely tell they're there and you'll be smiling from ear to ear. during cruise, at ANY speed, the cabin is as absolutely as quiet as stock. zero drone. at all. even at 90mph. WOT acceleration is where you'll really realize you're not stock anymore. These are LOUD at full throttle. These mufflers can be used for any Daily, even in an apartment complex,etc. I leave my tight complex at 5am 6 days a week and no one has complained. although its night and day compared to stock, you will still never ever wish these were quieter. Exhaust videos dont really sound like the mufflers actually sound. If you're looking for something a bit louder, get Corsa Xtreme. I feel like after a year of owning these, one might wish they were a bit louder. Overall, if these were double the price, theyd STILL be worth the money. Once you ride Corsa you'll never go to any other company.

      Everything I could have asked for

      I received my Corsa Sport exhaust 4 days after I ordered it. Quick delivery from American Muscle. I had it installed at a local muffler shop. They completed the install in less than 45 min. The look of the 4" chrome pipes are badass. The sound is true Mustang great rumble when idling and awesome sound when accelerating, but not to much to be annoying. No Drone at all.

      Review from Corsa Sport Axle-Back Exhaust - Black Tips (11-14 GT; 12-13 BOSS 302)

      Mustang 2014 GT CORSA Axle Back System

      I installed this exhaust system in about 2 hours. I took my time and did some cleaning of the under carriage while I was at it. Backed the car up onto a set of ramps and install was easy to do. I did move the pan hard bar down as stated in the instructions and it made the installation much easier. This CORSA system fit perfectly, sounds great, and the Black Chrome tips are different and look great. I as many listened to as many sound clips as possible and talked to different retailers about their opinion on sound quality and loudness. I also spoke with the CORSA representative several times. In the end I choose the CORSA Sport system. I wanted a high quality system with distinctive looks and a sound that is louder than stock but civilized when not fully into the throttle. The CORSA Sport delivers on all fronts. It also gives you the ability to modify the rest of the exhaust system if you want to add or change the sound such as adding headers, deleting the stock resonators or putting on an x-pipe in place of the factory H-pipe. In my option unless you actually hear the exact exhaust system you want you will never be sure of what you will get in terms on sound. In lieu of not being able to hear a system in person I think it is best to concentrate on what your desired sound level is, how you want the back end of your Mustang to look and if you are going to do any future modifications. The CORSA sport system will not disappoint, it is a great product.

      Best Exhaust set up.

      I bought the Corsa Sport Axle back and man let me tell you love the sound of it with all stock exhaust parts but then paired it up with Kooks Long tubes, high flow carted x-pipe and deleted resonators and it was a whole new symphony. Best part of it it's the awesome back firing it breaks necks everywhere you go. Love the set up and quality, will not go with anything else and will buy again. Highly recommend it.

      Bettter tone that factory with absolutely no drone

      If you are looking for something sounding better than factory with no drone these Corsas do the job. I had a set of Flowmasters for a year or so but the drone just old. The Corsa sound clearly announces these are not factory exhausts. At crank and idle they almost sound like you have a V-8. Put your foot into it and they sound great without waking up the neighborhood. Fit and finish is perfect. Chromed tips were angled perfectly (they are welded so you can't adjust them). Install was one hour with a 13mm socket and wrench. There are two brackets on the Mustang - I had to remove the bracket closest to the differential to get the Corsas on. Start to finish is about an hour. If you want something a lot louder than stock these are not for you. I really like the extra sound without any drone. Well done Corsa.

      Review from Corsa Sport Axle-Back Exhaust - Black Tips (11-14 GT; 12-13 BOSS 302)

      Black is beautiful

      Confirmed: No drone at cruise. Confirmed: Loud under hard acceleration. Had my mechanic install it, so can't speak to ease or difficulty of the install. Black tips look sharp against my ingot silver pony. Nice startup rumble. Very quiet at idle, though slightly different tone than stock. Wish it was a tad deeper note under acceleration, but it is definitely better than stock.

      Quiet at most times, loud at half throttle or more

      I tried to install these myself (backyard mechanic) with the Stang on ramps, but could not due to the lowered suspension. Too much interference with the suspension and/or exhaust pipe. Hired my mechanic friend who has a lift. He had to remove and reset the exhaust pipe. The sound is sweet. When engine warm, the exhaust is quieter, but deeper sounding. Volume increases with throttle increase. It can get VERY loud. Sounds louder than stock when first started until warmed up (30 seconds to near stock volume). After five minutes quieter than stock until the throttle opens. It puts a smile on the face of any gear head.

      Awesome

      Just installed this exhaust today (December 24th, 2014). What a great exhaust. There is absolutely no drone at all!!!! Louder than stock but much more quiet than a Roush exhaust. I ordered a Roush axel-back from American Muscle 4 weeks ago. I had to get it off my car. The drone was driving me crazy. This Corsa exhaust is very comfortable at cruising speed (2,000 RPM) whereas the Roush was horrible at cruising speed. Thanks American Muscle for your great service once again. My buddy has a lift in his garage. Took us maybe 40 minutes. Super easy.

      Corsa Sport

      I love these mufflers, quiet when at idle and highway speeds and nice sound when you get on it. Start ups are not that loud too. I did not believe such mufflers existed until I purchased the Corsa Sport. If you want same experience but much louder Durring hard acceleration than I guess Corsa Extreme would be the the better choice.
