        Worth it

        Put a new complete system on. From long tubes, high flow catted x pipe and new over axle pipes without resonators. These mufflers were the cherry on top. No drone when cruising. When you floor it, it’s freedom time...

        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.

        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.

        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.

        Great Purchase

        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.

      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.
