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.

Took close to two hours to install. Driver's side was a pain but passenger side was a piece of cake. Make sure that you remove the hanger brackets. Worth every penny. My wife's first statement, "it now sounds like a GT".Helpful (0)

Took about an hour to install from start to finish. The look is perfect on the back of the car. The tips are centered in the stock exhaust holes perfectly. The volume of the exhaust is a bit louder on startup and simmers down when the car goes to a normal idle. There is an exhaust tone change but there is almost no sound difference on the interior of the car when driving around the normal rpm ranges 2000 rpms-2500 rpms. When you open it up there is a major change in exhaust sound and volume. It actually sounds like a mustang now.Helpful (0)

Ford racing gt500 axel back
I have Cooks 1 and 3/4 long tube headers and catted x pipe along with these mufflers. Really nice sound and a bit louder than I anticipated probably due to the headers but still reasonable at cruising speed. Also, on a cold start up where your RPMs are initially around 1500 the neighbors will look over but it quickly quiets down to a low rumble. The 4 inch stainless tips look so much cooler than the stock tips with rolled edges. Just an FYI. I was going to go with the quad tip GT500 with Valance but decided to save a couple bucks and go with these. But still quite happyHelpful (1)

GT500 Axle Back Exhaust
I run a 2011 GT/CS. PURRS LIKE A KITTEN! ROARS LIKE A LION! Hard to keep my foot out of it. Ford did it right with this exhaust.Helpful (0)

Had a super loud exhaust system. Couldnt hear myself or the radio or a phone. New gt500 exhaust has a sweet note and no drone out. Its in my opinion the best sound a mustang can make. (5.0) Perfect daily driver.Helpful (0)

Bought the mufflers to tone down my exhaust on my 13 GT with kooks headers and high flow cats. Recently had Roush axel backs but they were very raspy and obnoxious. The GT500 style did exactly what I was hoping by bring the exhaust note down while still being pretty loud.Helpful (1)
I have been hearing that this exhaust will fit a 2014 v6. Is that true?
The Ford Performance GT500 Style Axle-Back Exhaust will not be a direct fit on the 2014 V6 Mustang due to differences in exhaust piping diameter between the V6 (2.5") and the GT (2.75")
Can any increase in horsepower / torque be expected with this system on an otherwise stock application?
Unfortunately the Ford Performance GT500 Style Axle-Back Exhaust will only increase the sound of the exhaust, and generally does not offer any performance gains.
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?
Yes they will work.
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.
Do these mufflers require any gaskets where they bolt up? If they do, are they included in the kit?
Gaskets would not be needed with this kit, no.
Unfortunately, we do not have listed decibel stats at this point in time for this setup.
These are designed for the 11-14 Mustang GT models. Unfortunately we have not confirmed fitment for the 2010 GT500 models.
The Ford Performance GT500 Style Axle-Back Exhaust is located after the catalytic converters which will allow this exhaust component to be legal for use upon highway in the state of California.
Yes, this exhaust will fit all 11-14 Mustang GT models.
We do have a quad tips exhaust set up for the 13-14 Mustang- https://www.americanmuscle.com/gt500-rear-valance-exhaust-2013.html
The Ford Performance GT500 Style Axle-Back Exhaust will weigh in at approximately 40lbs. At this time we do not have a reliable weight for the OEM axle-back.
The GT500 style exhaust is designed to work with 11-14 GT Mustangs models only and will not work with a 07 GT.
The Ford Performance GT500 Style Axle-Back Exhaust would be the completekit yes.
The Ford Performance GT500 Style Axle-Back Exhaust will quiet down the exhaust when compared to the Roush exhaust yes.
The Ford Performance GT500 Style Axle-Back Exhaust will only fit 11-14 GT Mustangs.
