Review & Installation Video

Review & Install Video

Hey, what's going on, guys? Adam here with americanmuscle.com. Today, I'm bringing you a detailed review and quick installation of the Ford Racing GT500 Style Axle-Back Exhaust, fitting all 2011 to 2014 Mustang GTs. So, in this video, I'll be going over the sound and expectations of the GT500 Style Axle-Back Exhaust, which, from the sound clip you just heard, gets a two out of five on our loudness meter. Then I'll talk about the materials and construction, of course. I'll top it all off with the installation, which, I'll let you know now, will get one out of three wrenches on our difficulty meter, something anybody can do with the right tools in the driveway at home. So let's jump right into it. With the sound clips you just heard in mind, you can already hear the slight difference between the '11 to '14 5.0 stock exhaust compared to that of which with the GT500 Style Axle-Back installed from Ford Racing. This particular axle-back from Ford Racing is the exact same muffler system that was used on the '11 to '12 Shelby GT500s, which, of course, is something that everyone wants to capture in their own S197. With that said, this isn't gonna make the world of a difference when it comes to sound on your stock 5.0, but, again, it will give you a two out of five on our loudness meter, making it something that does give you a slightly deeper growl compared to the stock exhaust, which, of course, is always a plus. And, of course, you're not breaking the bank here with something of a full cat-back, but you are still getting that slight difference over that stock muffler. There definitely are some good things about the Ford Racing GT500 Style Axle-Back, one of which is the fact that there is absolutely no drone involved with having this one installed on your vehicle, which is basically the overbearing exhaust noise you would hear inside the car. And, with this, it's just completely nonexistent. Now, a lot of people would argue that this exhaust should've come stock on all '11 to '14 5.0s, but, of course, it's never too late to upgrade. Now, with that upgrade, you're getting that slight throatier sound, and nothing too overbearing, nothing too over the top, and, of course, not the loudest option on the market, which is why I said, again, this one gets the two out of five on our loudness meter. Now, another couple of bonuses about picking up the GT500 Style Axle-Back from Ford Racing is that it actually is 50-State legal. Basically, that means if you're located in an emissions restrictive state such as California or a noise restrictive area, this one is going to comply with all local laws and regulations. Another bonus is if you're worried about voiding your vehicle warranty from the dealer, this one will not have to worry about that one, because it doesn't void any new vehicle warranty. Of course, you can always check with your dealer just to be sure. Now, as far as materials and constructions goes here, expect a very durable, long-lasting, 409 stainless steel for the mufflers and, of course, a polished 304 stainless steel tip with a four-inch-wide mouth coming outside of the rear end for your GT500 styling that will fit perfectly in your rear diffuser coming from the factory. Now, I do wanna point out that the welds here aren't the most beautiful, but, again, they will do their job correctly, coming from Ford Racing like a trusted name they have. Now, of course, when shopping around for an axle-back such as this, the price tag is always gonna be a factor, because you're gonna consider what you're getting out of it, how much you're spending, and all of that good stuff wrapped into one package. Now, with this option here, expect to be spending just about $400, which is a pretty typical price tag for a Ford Racing part like this. Although you are getting a two out of five in the loudness meter, it's not too crazy over the stock exhaust, which I would give a one out of five. This one is gonna give you that slight rumble over that stock exhaust, so if it is something you're looking for, about $400 for it. You're getting the 50-State legal emissions and noise, as well as a very simple bolt-on installation. Moving along to the installation portion of the video, like I said in the very beginning, this one is gonna be simple enough for anybody to care of with very light mechanical skills required. All you'll need is a simple ratchet and simple socket set. Now, with that said, you'll have to jack up your rear end. Of course, you wanna have a jack and jack stand on hand here. You wanna unbolt it, unclamp your factory axle-back, and, of course, pull them off from the over axle pipes, and, again, just simply swap them out with the Ford Racing GT500 Style using the hardware provided. The clamps are already even welded onto the end of the tips. With that said, once you get those bolted up, put the car back on the ground, and you're good to go. I'd say about an hour's worth of time overall, maybe a little bit more for those of you who aren't too familiar with the process, of course. Then, again, it gets one out of three wrenches on our difficulty meter. Just to wrap things up here, guys, if you're the owner of an '11 to '14 S197 5.0 GT and you're looking for a way to swap out your factory axle-back exhaust for something that gives you a little bit more growl coming straight off of the '11 to '12 Shelby GT500s, you might wanna check out the Ford Racing GT500 Style Axle-Back Exhaust, which, of course, is available right here at americanmuscle.com.

Will these bot up directly to BBK's Longtube headers and x-pipe? I want to install BBK Longtube headers and the offroad X-Pipe. Will these mufflers bolt up directly to them?

Which exhaust to go with? Hello, I was wondering which would be more beneficial, a catback exhaust or this axle back and an X pipe? I am trying to decide which direction to go in since the cost would be reasonably similar. Thanks.


  • Stick with the axle back...more than sufficient for sound quality and air flow. The GTs already have decent flowing cats and mid pipe exhaust, better than the V6s. Swapping out all the other exhaust pieces will get you a voided exhaust warantee and probably a failed emissions (if applicable in your area). The cost between the 2 options isnt even close.

Will they fit 2014 mustang v6 or they would have too be wielded?


  • Unfortunately this Ford Performance GT500 Style Axle-Back Exhaust is only intended for use with 11-14 Mustang GT's. We can not guarantee it will fit if purchased for a V6 Mustang.

  • The Ford Performance GT500 Style Axle-Back Exhaust has not been tested with the Pypes Pype Bomb Super System. We recommend contacting Pypes directly, as they will have all of the technical specs required to determine if these will fit since they designed the exhaust.

Can install these on the Mustang Ecoboost? I know the hangers dont match. A muffler shop can make it happen right?


  • The way the product comes out of the box is not intended to be installed on the V6 platform of the Mustang. However with some modification it may work but that is not something we can guarantee will work.

    Great Sound - Needed something less Obnoxious

    I purchased my first Mustang GT about 2 months ago. It had the HeartThrob (I think) exhausts which are essentially straight pipes by what I could tell. It sounded mean, but REALLY REALLY loud. As a mid-thirties guy and as a daily driver it just became too much. I purchased the GT500s and my 13 yr old son and I installed them in a couple hours. It is much quieter at idle and highway speeds and zero drone! It still sounds really good with acceleration and WOT but I don't blow peoples windows out just trying to keep up with traffic haha!

    These GT500 axle backs are perfect, no drone just excellent enhancement of the sound that Ford has engineered into our cars. Every time I'm cruising I'm hearing that great sound of Steve McQueen driving the green bullet car in the movie. Great shipping and service from American Muscle.

    Perfection, whisper quiet cruising between 35 and 55. Deep awesome sound when punching the throttle ( all mustang drivers do ) I didn't want it to sound like a Harley, I'm mid 50's not mid 20's. I have a 2012 GT convertible, so you hear everything. I am so glad I waited for these to come out, I LOVE them.

    Louder than Stock

    Exhaust is a little louder that stock without any drone at 65, 70 or 75 mph. When you get on it it is louder than stock with a deeper pitch. I wanted the Borla S but wasn't wanting to spend $800 on axelbacks. My exhaust and engine is otherwise completely stock. The tips are not chrome plated and sit farther inside the bumper than stock. I hope it won't discolor the bumper.

    Good, bad, and ugly

    I was astonished to see the huge box these came in. Ford racing really did a good job packaging the mufflers. I put my car up on ramps and took the mufflers out of th box, that's when I started to feel ripped off. The welds on these mufflers are terrible. The metal is scorched in several places and the alloy they used to weld it together was all over the place. They actually looked used. I had to take a good look at the inside to make sure they were new. Oh well, at least you won't really see that unless you're looking for it. I'll post pictures so you can see what I mean. The install was straightforward, there are no instructions, but if you can get your mufflers off you can put new ones on. The sound is okay. I have an o/r h pipe and it has a slightly sport bike tone to it while cruising. When you get on it the sound is pretty loud and maintains a decent tone. I'm not really impressed or disappointed.

    GT 500

    I am very pleased with the GT 500 Exhaust. It replaced the Flowmaster outlaw series. The drone from the Flowmasters was horrible and there is virtually no drone with the GT 500's. They are quiet when they need to be and expressive when they have too. The install took right around an hour to complete.

    I installed a Steeda cold air intake and a performance tune. Next morning took car to Midas and for a mere 70 dollars had the mufflers installed. All I can say is Wow! Like everyone before me has said, the appearance of the larger tail pipes is great, but the sound improvement just can't be properly stated in words, but every comment I read was accurate. Great sound at all RPM's and no more drone! You can't go wrong here. Buy them and you will love them.

    Great Exhaust

    I listened through many sound clips of various axle-back exhausts and read a ton of reviews before deciding to purchase the GT500 axle-backs. They are exactly as advertised, factory quality and fit, and a good upgrade over stock sound. Cold startup has a nice deep V8 burble to it, once the engine gets warm it blends in and is only slightly louder than stock. You can hear the difference when you punch the throttle and it sounds great, but under normal driving conditions it is barely louder than stock, and absolutely no drone. Pretty easy install, took about an hour and nothing unexpected, did it myself with basic hand tools and jack stands. Would highly recommend for those like me looking for a more aggressive sound when getting on the gas but not wanting a loud and annoying exhaust during daily driving.

    Best sound at best price

    1) Loudness and Note. The exhaust is much louder than I anticipated from YouTube videos and the like, but in a good way. I was very pleasantly surprised when I fired her up. The note and volume are both perfect for me. I wanted something that screamed muscle car but still sounded like something from a factory instead of just pure obnoxious noise, and that's exactly what I got with this product. 2) Fit & Finish. Fits perfectly and looks like stock, but installation can be really tricky especially if you're alone so even when you finally get it mounted make sure to take a step back and make sure it's not touching any body or otherwise misaligned. I had to re-tweak my efforts a couple times. 3) Installation Time. I rated this at Afternoon but it took me something like 4 hours with a friend. Personally, this is the best axle-back exhaust I've heard out there and somehow it's also the cheapest. Buy it and enjoy.

    Loving The GT500 Axle-Back

    I must admit I was shocked to hear, feel and see what a difference this Axle-Back Kit made in my GT. It's more throaty, and has better tone without being loud or obnoxious. It's the perfect enhancement for someone that wants a little better sound, but doesn't want to awaken the entire neighborhood when they drive by.

    Great sound, great price.

    I was looking for something with a slightly more agressive with a deep, almost subvocal "thrum", but without roar or drone. After countless sound samples and YouTube videos, I decided that this one sounded the best for what I wanted. The big surprise was the price, which was very reasonable. Installation was relatively easy, and the bolt-on clamps made fitment and adjustment a breeze. The only issue was that it came packaged in a Ford Racing box, and the tips are NOT padded enough for the way UPS treats a box. The weight of the mufflers caused the tips to punch through the styrofoam padding and hit the cement of my porch upon delivery, bending it and scuffing it. Luckily, the tips are not super-buffed or double-walled, so I was able to hammer it out with a mallet and a wood dowel, though there's still a bit of a scuff. The tips themselves are pretty no-nonsense. Nevertheless, I'm very happy with this muffler. Car is a 2012 Mustang GT with the stock H pipe.
