Shelby GT500 Styling and Sound. This Lower Rear Valance and Axle-back kit is the exact same one that is featured on the Shelby GT500 Mustang. Offering aggressive race inspired styling and sound this rear diffuser kit makes the perfect replacement part or appearance upgrade for your Mustang.

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.

GT/CS No Bumper Removal? So this fits the GT/CS bumper without having to cut anything since it's split the same way, can I just swap out the two valances without removing the bumper at all? Or do you actually have to remove the bumper to be able to reach the valance clips? Thanks.

  • While the GT/CS bumper may be similar, to ensure that the install is done correctly please follow the guide that is given for the Ford Performance Shelby GT500 Rear Valance & Exhaust Kit (13-14 All).

size of the tubing what is the size of the tubing of this exhaust, the end that goes in the x-pipes or the H-pipes

Biggg

  • The same size as the factory axle back. I believe it is 3". If you added the x-pipe to the stock axle back, you shouldn't have any fitment issues. I added this kit to my 2014 GT\CS, and it looks and sounds Amazing! Good luck!

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.

    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.

    Installed the quad exhaust in about an afternoon, couldn't be happier. Great rumble, no drone, and cruising at 1800rpm sounds amazing. You do have to cut your bumper, but there are lines on the inside of the bumper that tell you where...but still...you are cutting up your Mustang. I spent an afternoon (about 5 hours) on mine, taking my time and I had the help of one other person. Anyone with a little DIY in them can knock this out.

    This is the exhaust to get. People were saying to get Borla and that this won't make much of a difference on my 2014 v6. The sound is unbelievably better. Throaty like a muscle car, not sporty. Also very loud. Looks fantastic as well. The diffuser is the unsung hero in this bundle because it is so beautiful. Also, since the diameter on the pipe is different on the v6, it had to be welded.

    Sounds awesome

    Easy to install just take your time. Sound is unbelievable but pleasant at cruising speed. Spray paint the muffler walls with hi-temp black. Paint them before you install (not sure why Ford does not do this for all mufflers).

    sounds like 400 horsepower car now

    pretty straight forward install, took me about two hours in my driveway. being factory Ford parts the fit was perfect. to cut the bumper, I used a dremel with 1/8" multipurpose rotozip bits, recommend doing a test cut in the area you'll throw away to get a feel for it, then trace the line on the inside of the bumper. I used Ford's install instructions here, http://fordracingparts.com/m/CatResults.asp?c=54#/m/Part.asp?p=23404 gives the car a nice loud aggressive tone without being obnoxious, yet quiet enough to not disturb neighbors on early mornings and late nights as long as you keep your foot out it.

    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!

    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!

    Awesome appearance, great fit and sweet sound!

    First of all, I love pretty much everything about this exhaust! The install was very simple and straight forward and the valence was a perfect fit! It looks amazing! As far as sound of the mufflers; I have an off-road x-pipe and resonator delete on my mustang so those upgrades paired with the GT500 exhaust sounds MEAN! I do wish it were a little louder but still i'm not complaining it sounds great! This kit is a tad pricy but totally worth the money! And of course, as always, awesome customer service and fast shipping from AM!

    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

    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.

    Love it!!

    My brother and I did this install and it took an entire day. I labeled afternoon because neither of us are mechanics so we really moved slowly and took our time. What can I say the product looks great! The sound is awesome, (people looking for really loud exhaust this is not for you!) I love the deep rumble that isn't deafening, no drone at all, very tame at high speeds, sounds great around town in the lower gears and downshifting.I prefer a tamer exhaust, I like to have people riding and I want them to enjoy it as well. The best thing hands down is the look! completely changed the rear end of the car to a more aggressive and sporty look with the quads and valence. As I said the install was not difficult, just took us a while. One note that helped was i used a jig saw for some parts, if you can, use a body saw. Anyone can do this install! Highly recommended!

    Amazing exhaust!

    I won this at the American Muscle Mustang Show 2014 at the raffle and I could not have been happier. I had been debating getting an exhaust over the summer but chose not to and instead saved my money. I had a local auto shop install this because I have a 2014 V6 and the V6 requires welding, which is not my bag, baby. I picked it up after a half a day and I am in love with my car all over again. Sounds meaner than I imagined! No drone either!
