        How much louder are these than stock? Looking for a more aggressive sound than stock but do not want something obnoxious.

        • The Ford Performance FR500 Exhaust has a very nice and throaty sound that easily beats the original factory exhaust without having to settle for an obnoxious option. This will have a nice muscle car sound when accelerating and a nice quite sound when driving at highway speeds.

        Can these be modified to fit a 2011 GT?

        • This axle-back exhaust is desinged to fit the 2005-2009 Mustang GT models only and unfortunately will not work with the 2010 and up models.

        This is a good price for this exhaust. Can you confirm that this item is an actual Ford factory part which would normally be available from a Ford dealer or is it an aftermarket reproduction?

        • This Ford Performance FR500S Axle-Back Exhaust (05-09 GT, GT500) is a genuine Ford Performance part. The MPN M-5230-S listed below item number stands for Manufacturer's Part Number and can be cross referenced to Ford Performance's website as well.

        I have a 2006 GT it is automatic. Would there still be an advantage, "thrill" of adding these? I see people talking about being in 5th gear, etc. Will I see that benefit with automatic transmission? Thanks

        • The Ford Performance FR500S Axle-Back Exhaust would still provide an aggressive tone and louder exhaust note than your stock axle-back exhaust.

        Is this axle-back exhaust louder than a corsa xtreme?

        • The Ford Performance FR500S Axle-Back Exhaust is definitely one of the loudest exhausts offered for the 05-09 GT models. When compared to the Corsa Xtremes, I would honestly say they are actually very even in terms of how loud they are. Both offer a very aggressive sound.

            Ford engineers get it right

            If you look down inside these are actually straight thru resonators. So... tuned for NO DRONE at all (thank you Ford racing!) yet rattle the windows when mashed! Dad is going to hear you when sneaking out of the girlfriends house, but the neighbors will be happy enough. On a stock 2005 w cats. Oh, and they fit like a glove, unlike the other ones I had.

            Nice

            I had the Pypes Pipe Bomb before these and they had way too much drone to them. I wanted a nice deep sound without the drone so I took the chance on these. They are definitely worth it. Real nice sound on start up and when you are on the gas. When you have the cruise set, they tone right down very close to stock. That is what I was looking for, a nice growl when on the gas and no drone when you are at a steady speed. Nice exhaust.

            2008 GT 500 Fr500 axel-back

            Ordered the FR500 exhaust for my 2008 Shelby GT 500 got them in on time opened the package and the exhaust was in great shape,put the car on Jack stands in the driveway and removed my old stock exhaust,installed the ne FR500's in about 45 min with no problems at all fit and finish was perfect! I took several weeks reviewing and listening to sound clips of the mufflers and the tone was spot on they sound great BUT not as loud as I wanted,I am not disappointed at all and would not chang my choice,I will be installing a Off Road X pipe to get the volume I'm looking for and if that doesn't please my ear I will add long tube headers lol! If you are looking for a mild GREAT sounding axle-back this is your best choice by far!

            You Pay For Quality! , 5/5

            I recommend you install these yourself due to the fact that it will make you feel more connect with your Pony. This took me and my brother about 1.5 hours, we i dont work on cars on the daily. The Axle back fit like a glove. Now onto the fun part... i have a 2006 Mustang GT (AUTO) 80k miles and i replaced the original owners Magnaflow. Magnaflow cant even come close to the FR500s. This car grumbles in all the right places with ZERO drone, i dont even know how its possible to get as loud without drone? This Axle back is not cheap, but with the Ford Stamp onto my Mustang GT i will never buy another exhaust. I will say it is louder when you first install and do a few Pull so it drops from 5 / 5 to 4/5 on the loudness after about an hour of driving. The popping sound will subside fairly quickly, but all u get is pure mean Grumble as a GT should sound end of story.

            Like angels singing......

            I spent weeks researching and listening to sound bites..... Sound bites do NOT do these justice. I have stock exhaust and these are perfect. Deep throaty muscle car sound without being obnoxiously loud. Sounds EXACTLY how a Mustang should sound and ZERO drone. I got the idea from another reviewer to paint the cans flat black to make them disappear under the car. Used high temp grill paint, and it worked perfectly. Had a shop install in less than an hour for $60, and after install they looked a little like Marty Feldman's eyes....... His welding guy was gone, thank God since he quoted me $100 to even my pipes out. Midas, you're fired. A quick trip to an actual exhaust place, sawed off the low side hanger, cut a piece out, welded it back. Ten minutes and $40 later I was on my way. I highly recommend these!

            Sound that gets attention

            This was an easy install, and what an upgrade! The sound when starting, idling, running, and especially revving is so dramatic. Heads turn. And the aesthetics of the tail pipes is a major plus.

            Awesome sound

            After reading many reviews and listening to a lot of sound clips, I went with the FR500S axle backs. I am100pleased with my decision. My Stang now sounds like it should. Just the right rumble and a glorious roar when opening up. Sound is a little louder than stock when cruising at highway speeds and zero drone. If you are looking to upgrade your mufflers, d not hesitate. Get these, they are just as the reviewers say. Buy from American Muscle, best price and I received mine on third day from ordering. Installation was 2 hours, no lift, just worked on the ground. Exact fit.

            The Best Sounding Exhaust on the Market

            I purchased my 2008 GT with a set of Flowmasters already installed. They sounded nice and burbly, but the drone was terrible when cruising, just absolutely awful to commute with. The FR500S axle-backs have completely transformed my car. There's absolutely no drone and they're downright civilized when cruising around, but when you open the taps they scream louder than the Flowmasters ever did. I've always been in love with road racing Mustangs from the 60s and very early 70s, and that's exactly what my car sounds like now when on the power. Raw and raucous, with pops and crackles on the overrun. This was the best investment I've made for the car to date.

            How your Mustang should sound!

            The FR500S Axle Back is one of the first modifications I've done to an otherwise stock car so far, and what a difference! The new exhaust tone is impressive, with a low, trans-am race car like rumble at lower RPMs that would make you think your car has cams. Full throttle is another experience entirely, and the FR500S mufflers come alive with a great, aggressive bark Cruising, they are barely audible at highway speeds and make for a pleasant ride. On deceleration, they make great popping and burbles. As others have stated, there is NO DRONE through any RPM, which was the main attraction for me to this set-up. They are a quick afternoon bolt-on to really liven the experience of driving your Mustang. The longest part of the install was using a box wrench to get the hanger bolt above the factory mufflers on both sides. Once the factory mufflers are off, the FR500S mufflers are routed perfectly around the bolts to be able to use a socket set or power tools. The original packaging from Ford left a lot to be desired, and my axle-backs were boxed with no other packing materials then some bubble wrap around the tips. The box was tattered when it arrived, so be sure to inspect carefully for any damage. Additionally, I'll knock a star on fit and finish because of the weld splatter on the mufflers. It could be cleaner. Overall, the FR500S axle-back has taught me you get what you pay for: OEM quality, great aftermarket tone and no drone! These are a definite must have!

            WOW! Just what I was looking for... FINALLY!

            So many people say they should have bought these years ago. I couldn't agree more! I have a 2007 Mustang GT 5 speed with 3.55 gears and the Ford Racing cold air intake and tune. Everything else is stock. I wanted louder exhaust but still be able to daily drive with kids and my wife. I tried Flowmasters with the Super 44's and could not handle the drone. Sound quality was not the best. Also fit and finish was poor. Went back to stock mufflers and then came across some youtube videos of these. I cannot believe first how well they fit. No adjustment needed. Tips look great! But then the sound... The sound is AMAZING! Start up is exciting every time. Under normal driving, you hear the growl but it isn't too loud. Just sounds like you have something without screaming it. And will make you smile every time. My favorite may be accelerating part throttle to about 3000rpm then hit the clutch and slowly shift so I can hear the exhaust gurgle down to a lower rpm. When you get on it, these mufflers open up! Sounds like a race car and will get people turning their heads! To me it is the absolute best; loud when you want it loud. Quality sounding rumble for normal driving and NO DRONE. I agree with others when they say it may actually be quieter in the car at 60mph cruising. As soon as you hit the gas, you hear them but cruising is silent. About me so you understand my viewpoint: I am 37 years old. I have a 68 Charger with built 383 with dual 3" and Magnaflows. Its loud all the time. Sounds great but definitely too loud for daily driving. I also have an 82 Cutlass with a 350 crate engine breathing through dual 2.5" and hooker mufflers. This is very loud and raspy all the time. Again fun for me to take out on the weekends but not so family friendly. The FR500S mufflers on the Mustang get loud similar to the others but are much easier on the ears for normal cruising. They seem like they have an active dampening system like new mustangs and others are coming with from factory. They really are amazing. The sound just makes it all worth while. I cannot wait to drive the car just to hear the exhaust. I have about 1000 miles in the exhaust and its still just as exciting as the first time I started it with the new mufflers. Watch video's on youtube. There are plenty. Then go ahead and make the purchase! Don't wait like I did.

            Droneless with Great Bite

            I've got a 2008 v6. This is, by FAR, the best muffler you can get for one. I've been through others, SLP etc, and all had drone and didn't achieve the legit, deep growl I wanted through the whole rpm range. You'll have to convert to duals for these, but it's worth it. I paired it with a MAC prochamber and catback piping, which did not line up well at all with it. It may be because it's a 6, it may be better with ford performance dual conversion, who knows. But the sound is insane. -No drone -Burble at idle -Quietish at cruising rpm, screams at WOT -High Quality It's not exactly cheap, but if you want to do your car right it's the right buy.

            Very disappointed

            After reading tons of reviews I decided on to get the Fr500s axel backs but they weren’t what I expected. The pretty much sound stock and are not as aggressive as they are advertised. My sisters v6 with magnaflows sounds louder than my v8. I’m very disappointed in AM for saying that these are some of the most aggressive ones available. Wish I could return or exchange them
