Add Horsepower. Stop choking your Shelby GT500 with a stock factory exhaust system and enjoy more horsepower with a Magnaflow Competition Axleback. By reducing back pressure and giving your Mustang GT500 a free-flowing exhaust, you'll see great power and torque gains.

Aggressive Muscle Car Sound. The Magnaflow Competition Axleback has a straight through muffler delete design for minimal restriction and the most aggressive sound you can get with the stock factory cats still in place all while improving exhaust flow for more power.

Magnaflow Quality. Constructed from 100% stainless steel for long life and durability, this Magnaflow Competition axleback exhaust system features free-flowing mandrel bent 3" tubing and two quad 4" black finished tips that exit in the stock locations for impressive styling.

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

    I put these on my 2011 GT

    I have a Saleen rear bumper and lower valance that has large exhaust openings to accommodate the 2013 GT 500 quad tips. They quad tips look amazing and are seriously loud without mufflers. My GT is set-up for road courses and a I track my GT at HPDE's regularly. The loud exhaust note will need to be toned down...I will be adding mufflers in the near future.

    Amazing just amazing...

    Put them on my 13 GT500 less then two days ago and I've fallen in love. Had them installed by my local performance shop. Install took less then an hour. As soon as I started the car after installation the entire shop jumped. No one expected for a axle back to make that much of a difference. If you own a 13 GT500 this needs to be your first add-on not only does it free up some extra HP but it also gives your beast that race car sound.

    Wow - You want Loud & Aggressive? You got it with these...

    I simply wanted the most aggressive Axleback I could find and this is definitely it. Quad Muffler Delete. Finish is great. The black color is mean looking. Fitment took a one star hit only because it was a little difficult to align the driver side ---- needed some hangar bends to get the alignment correct, but not bad at all. Now, when I cranked it up, oh wow. Exhaust note is very aggressive and really turns this beast into a bigger beast. I don't really notice any drone ----- maybe a little at 1900-2200 RPM. Overall, if you are just going with an Axleback and you want loud, aggressive, and mean, install these. You won't be disappointed.

    a great product

    I just got the axel backs for my 5.0 GT/CS and their amazing, but for some reason the right one sticks out more the the left one and the machanic said it's longer than the left one and he suggested me to cut it and I didn't so I kept it that way. overall they're just amazing and I'm in love with the sound

    2014 GT500

    I've never had Magnaflow products before, but I am thoroughly satisfied. The weight saving is ridiculous and the sound is awesome. Highway drone is pretty common with aftermarket exhaust; I don't notice it at all with these. In town driving around it sounds like it should, then on the highway they aren't noticeable. A++ My only wish would be that they were made in chrome, but that just has to do with Magnaflow. American Muscle is a class act, my exhaust were shipped and received before I even expected them to be in stock.

    No Muffs

    I purchased this exhaust with the rear valance which was sold separately. I am giving the entire kit 4 stars instead of 5 because CJ pony parts sells them together at a cheaper price but the sake of convenience I still purchased the kit thru americanmuscle because there was a 15 dollar coupons I used but i still paid slightly more of 5 dollars for the entire kit. They gave me the option to call but I decided to dive in and purchase them anyway. The exhaust package was huge when I received it from the mail. Since I wasn't familiar in installing the exhaust myself or the rear valance I taken it to a shop to get it done professionally. I was quoted at 150 dollars which seems fair. The installation taken 3 hours (since the old exhaust needed to cool down a bit). When I got the call to pick up my car the mechanics were complimenting the sound. The moment I turned my ignition I was immediately overwhelmed how loud she roared. Even on when she was idling she growled like no ones business. I was definitely pleased how she looks on my car. I love the fact these exhaust have no muffler and how it compliments my car being white. Not only it will make her loud but I had noticed my car has gotten faster in accelerating. This is definitely worth your purchase if your planning to buy a new set of exhaust. It will really make your car look like your driving a gt500. You can't go wrong.

    Too loud

    I bought the bbk shorty x pipe and long tube headers with it and installed them on my 2014 GT. The sound is just brutal and I love it. However, I have to point out that if you are a daily driver and you drive the car more than 1 hour per day, that loudness and drone will make you go deaf in a couple months. Also if you are going mad fast on the street, the cops can hear it from miles away. Besides that it's perfect.

    The perfect exhaust for a modern muscle car!

    Great exhaust overall. This exhaust is exactly what I was looking for; it has a great blacked out look and is extremely loud with a great tone. This exhaust is not for the faint of heart or for anyone that wants a sleeper. The only downside is the price; however, if you want a quality product, it usually comes at a price. Finally,it fit well and was an easy straightforward install.
