      Application. Made to be a direct bolt on, this Magnaflow catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on your the 2013-2014 Shelby GT500 to give it the deepest, most aggressive sound possible.

        Great sounding exhaust that bolted right to factory mid pipe. Install took me and neighbor 3 hours. Had to drop rear end to get the clearance needed using jack stands. Overall not to bad.

        Super mean!!

        I put this on my 13 gt and it made a huge difference, if your scared of getting pulled over these aren’t for you! Super loud and mean Super easy to install if you’ve messed with exhaust before but will not work so well without a lift

        loud easy to install

        This is my 4th mustang and 1st Shelby and doing exhaust on these cars is pretty straight forward. If you have a lift this shouldn't take more than a half hour. The sound is super aggressive with a slight drone around 2500 rpm. This will wake up your neighbors every time you start up.

        Not for your incognito people. They are LOUD but tasteful still. Compared to Corsa and Borla these are way cheaper with the same result, obviously due to no muffler as well. Simple install just use common sense

        2013 Mustang GT

        Overall pretty good buy, I wouldnt recommend this for daily driving. It drones way too much on the highway and the exhaust is so loud its almost obnoxious. I love the mean aggressive loud sound, so i dont care what others think but your neighbors will definitely hate u after just 1 day. Easy install maybe 30 mins real clean look. Just super loud!!!!!!!!!!!

        My Ears are in Heaven!!

        I bought this catback along with the GT 500 rear Valance for my 2013 Mustang GT, to replace the GT500 axlebacks that where on it from the previous owner. What a upgrade it was too! The sound this exhaust makes is just flat out mean as you know what! When I cranked the car up for the 1st time the sound literally scared me. I didn't expect it to be so loud and aggressive. You can feel the extra power the catback gives you as soon as you take off, the car really gets to breath. I would highly recommend this catback exhaust to anyone that wants their Mustang to sound just flat out mean!

        Magnaflow Competition Catback Exhaust w/ Black Quad Tips look amazing on our 2014 Oxford White GT Mustang

        I don't have a single negative thing to say about this kit... it looks and sounds very aggressive. If you are installing this on a GT, don't be nervous about trimming your lower bumper to install a GT500 valance. It wasn't too difficult at all and this exhaust is sure to turn heads! We have a lot of people ask about it at meets and it gets the car many compliments. Not sure how much power we gained from it alone because we installed a JLT cold-air and Bama Performance loaded SCT x3 tuner as well. Thanks again AM!

        Took me longer since it's a catback and I don't have a lift so we had to lower the rear axle but it was worth the time, everyone turns and it is extremely loud. Literally scared me the first time we turned it on. And the quad looks amazing too. Very good choice

      5 Top Rated Questions

      Will it be a direct bolt on to complete stock 2013 5.0? (Aside from having to cut out the valance)

      • This Magnaflow Cat-back Exhaust is basically a bolt on application, though they will require clamping at the downpipe after cats.

      Helpful (1)

      Will this catback exhaust bolt on to the factory h pipe on my 2014 5.0?

      • Yes.

      Helpful (1)

      Does this system have resonators in it in front of the rear axle like the factory system? I see several systems that specifically say that they delete the resonators but this one does not.

      • Yes, this will be replacing everything after your mid pipe so once installed on an otherwise stock application, you have a mid pipe, cats, and headers.

      Does this exhaust system pass emissions in New York?

      Would this bolt straight up to a 2014 gt stock midpipe? Or would there be more modifications to the piping necessary?

      • The Magnaflow Competition Cat-Back Exhaust w/ Black Quad Tips will work with your mid-pipe however you will need to get the GT500 rear valance for the quad tips to work.
