    Axle-Back. Constructed from high quality stainless steel tubing with dual slant cut stainless steel tips, this Shelby GT500 Axle-Back exhaust system features specifically engineered Straight-Through mufflers to eliminate that annoying exhaust drone that is heard at sustained RPM's.

    Rear Valance. Made from OEM quality high pressure injection molded thermal plastic for it's long lasting durability, this rear diffuser valance features an OEM grained texture for increased longevity against rock impacts from daily driving.

    Application. This Rear Diffuser and axle-back kit is a direct fit replacement for the 2013-2014 Shelby GT500 and BOSS 302 Mustangs, can also be installed to upgrade the appearance and sound of your V6 or GT models with modifications.

    GT and V6 Installation Note. Installation of this Shelby GT500 rear valance diffuser on a GT or V6 model will require modifying the factory rear bumper fascia cover. You will need to cut and remove the lower section of the cover and cut slits to retain the valance. Fortunately, Ford pre-marked the backside of the factory fascia cover showing exactly where you need to cut, making the job much easier. Due to differences in the size of the axle-back piping diameter, V6 models will require additional exhaust modifications.

    Fits the item above under the 2013 GT/CS without cutting the bumper? Do I have to cut the bumper of my 2013 GT/CS so that the GT 500 Rear Valance fits or does it fits without cutting the something??? The bumper of the GT/CS is split like the GT500 bumper. Thanks and regards, Carsten Bruns

    • No you don't have to cut anything. It clips in just like the CS diffuser.

    Can anyone tell me the difference between this axle-back and the other Gt500 axle-back sound.

    • This axleback here is the factory axelback included on the Gt500 mustangs, whereas, the other GT500 ford performance axleback featured a single exit so it could be used on the normal GT's while having a similar sound.

      Looks great and arrived fast

      As of this review I have yet to install it, but I cannot wait! I’ll be able to post some videos of the sound with an O/R x pipe and Borla over axle tubes soon so people can get the gist of the sound. Overall the parts arrived undamaged and all the necessary hardware and ford instructions are there. As always American muscle was extremely helpful and I appreciate there customer service tremendously. Thanks again!

      Sounds great with off road x and no resonators, not really loud at all. Good mufflers for someone that drives and travels a good bit. Valence fits good pretty simple

      Solid exhaust

      I bought these exhausts for the look, sound and reliability. It hasnt let me down in any of those factors. Sounds great with my off road x pipe, long tube headers, and over axel pipe. Literally the perfect sound. Not crazy loud when im driving around town but when I get on it she screams! Definitely worth the price and looks amazing

      Meanest sound for a 5.0

      Fantastic exhaust. I had the rear valance installed professionally, and swapped the mufflers. This is the meanest exhaust you can get for the 5.0, it keeps it deep and rumbly down low, and roars wide open. No drone too. If you pair this up with LTH over axle pipes and a JBA H-pipe you'll have an amazing sounding 5.0, I got compliments everywhere.

      Great Purchase For Sure.

      The sound of the car from the manufacturer wasn't bad, but I knew it had to be enhanced. I didn't want to be obnoxiously loud, but the V8 needed justice, so I bought the GT500 exhaust and did it myself in my garage in about 5 hours. Before trading in my first car Betty, a black 2007 V6 stang, I knew the next car had to be a mustang. I ended up getting a 2013 5.0 and I fell in love all over again, I noticed the sound was pretty quiet even if you put the hammer down with the stock exhaust so I decided to look up different exhausts and this one had me from the start. The sound is incredible from idle to redline, and a quad exhaust looks amazing on the tail end. It is a perfect exhaust all around the board. I never waste time with reviews but this one deserves it. Get it.

      GT500 quad tip exhaust

      The videos i have seen of the exhaust note do these no justice. Couldn't be happier. They fit perfectly, look amazing and love the sound. Much more Mustang sound without being obnoxious.

      Changes EVERYTHING!!!

      I didn't like the huge gap of the stock exhaust cutouts, so I wanted this to fill that ugly gap, and also loved the look of the quad tips. Great sound too! I didn't want anything too loud, or with a lot of drone. These have ZERO drone, and are quite a bit louder than stock. And be prepared for the symphony of snaps, cracks, and pops (Bacon!) when letting off the gas or down shifting! I would not recommend doing this on your own unless you have experience and the right tools. My lift and body saw turned this into a 2 hour install for me, plus an extra set of hands played a huge role in that.

      GT500 Valance Exhaust review

      Hands down the best purchase I have made for my mustang. Installation took a while but in the end it was worth it. After installation, it looks like it came out of the factory like that. The Exhaust tone and note are perfect (I did get my resonators deleted by a local shop). This exhaust is perfect for someone that is looking for a quiet cruiser that can also be very loud on demand.

      Sounds good, looks amazing!

      Just installed this on my 13 GT/CS. Since it was the CS I didn't have to remove or cut the bumper so that definitely helped with the install. Overall, it was very easy and it looks great! It's a little bit louder than the stock mufflers (everything else on my car is stock) but has a really good rumble to them, especially in the low end. They're a little pricey, but I'm definitely glad I made the purchase. And as always, AM is the best service!

      First off the kit was delivered fast and packaged well. The fit and finish was perfect. YouTube instructions were easy to follow and it looks awesome. It's very quiet cruising but sounds great when accelerating!! Couldn't be happier.

      Sick Axelback

      I've been deliberating on which kind of axelback to get for my mustang for a while. I was looking for an exhaust that was louder than stock, but not too raspy or obnoxious. Finally pulled the trigger on this kit and couldn't be happier. My review below: 1. The sound: A very deep growl, roars when you hit the gas. Sounds perfect. Sounds way better than on the youtube videos. 2. The appearance: Looks beast. The quad tips are really sharp, and the black rear valance looks good with deep impact blue. 3. The price: Definitely pricey. If you don't need the valance, then you can just get the mufflers on ebay for a decent price. However, I needed the whole kit, along with a shop to install it. The install cost was 366$, so along with the original parts that's a good bit of cash spent. Overall I'm very happy with the purchase an have no regrets! I'm aware that mufflers don't really add HP, but it sounds like mine gained 100.

      The best exhausts on the GT!

      I had always wanted the Shelby look on my '14 GT and planned to get these even before I actually bought my car. The sound from the exhausts is definitely louder than stock. The kind of loudness I like and that people appreciate. I never wanted something that is so loud that cruising on a road trips gets irritating with other passengers. The best part is the throaty noise that it makes and the little pops and crackles upon downshifting or letting off gas. Puts a smile everytime I do that :) My car now sounds like a proper V8 with 420bhp :D

      GT500 Quad Tips are GLORIOUS!

      At first I was unsure of what exhaust to get for my v6. Borlas seemed to be a crowd favorite, but I had also heard some bad reviews on them, and they are becoming increasingly common and I felt the need for something a little different. And WOW am i glad i stumbled upon these!!!! they are hands down a no brainer for any mustang owner. The sound that these exhaust with the combination of my Airaid Intake sounds phenomenal. Smiles per gallon have skyrocketed! The bumper was needed to be cut to fit the valence on, but that was a task easily handled by my local bodyshop, the actual install of the exhaust was also handled by a shop, and they were done in less than an hour. There is virtually no drone, and its almost as quiet as stock when cruising or when you want it to be. But punch it, AND SHE SCREAMSSSSSS!!!!! very deep true muscle car tone. I could not be happier with my purchase. If you are on the fence about these exhaust for your V6 look no further these babies are worth every penny!
