    Does this Axleback system and the Borla ATAK Axleback have a similar volume or is one significantly louder than the other?

    ThatTungstenGT

    • This exhaust and the Borla ATAK exhaust will have similar sounds as mentioned with our loudness meter on the axle-back exhaust page. However in direct comparison, the ATAK exhaust will be slightly louder as the muffler chamber is smaller in size and shape than that of the FR500S axle-back exhaust.

    I have a set of Bullitt axlebacks on my 2010 GT yet it says the FR500S axlebacks arent compatible with my car. I basically have the same engine as on the Bullitt ( really regret it a bit having bought this odd model year because it's either listed as 5.0 which it isn't or you have to research a lot to make sure the parts fit ) Are the hangers different? The Bullitts sound ok but lacks some deep sounds, i assume the FRs would do the trick? Also are these originally for the GT500 or GT?

    AlexanderA

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

    KurtM

    • 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.

    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?

    Jesus127

    • 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.

    ANYONE KNOW IF THESE ARE LOUDER THEN THE ROUSH AXLE BACK?

    Roly

    • Hello, RolyT5U1501189 We rate both systems about the same when it comes to loudness, With that being said the roush is a bit deeper.

      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

      This should have been my first mod !

      I fell in love with the car again. I'm kicking myself for waiting this long. Now it sounds like a Mustang ! I find myself downshifting constantly just to hear that awesome sound. Its loud when you want it to be and totally tame (almost stock-like) when just cruising. No drone ! And I got a little of my snap, crackle, pop back again which I lost after the bama tune. You can't go wrong with these. It is louder than stock (obviously) and I was worried about early morning start ups but its fine.

      Ford performance exhaust

      These axle back mufflers sound really good but a warning to you if you have an off road X pipe and want to quiet some of the rasp down these mufflers do not do very well for that I originally had magna flow muffler delete pipes on and that was totally insane for loudness these mufflers quieted it down a little bit but not as much as I was hoping for I just have to live with my neighbors being irritated with me LOL but overall a good product fit Well and sounds good

      That's the sound I wanted

      My 2008 GT has had a set of FlowMaster Thunders since about the 10K mark. They were annoyingly loud when traveling the highways as we do. I even added DynaMat to the entire interior with little quieting. Now at 76K, I wanted a throatier sound with no drone. After much research, I selected the FR500S, and I couldn't be happier. Loud when I accelerate, and quiet when cruising. I really don't like seeing the mufflers so I always paint them with high temp black paint. These took some cleaning before painting, as they do not come in a clean finished appearance. Ford needs to re-think their packaging, as with no noticeable damage to the box, the one muffler dented and scratched the chrome tip of the other muffler, as bubble wrap does not stop metal from damaging metal. Since I have experience with 5th Gen Mustang exhaust installation the installation was straight forward, but for some reason on my Mustang I cannot get the two exhaust tips level. It may require loosening the connections between the high flow cats and the x-pipe. I try that the next time I get her on the lift.

      Awesome!!

      Very easy to install. Great look. The sound with these is unbelievable! This is the way all V8 Mustang's should sound! I couldn't be happier! One of the best moves I've made with mods. Pricey but totally worth it! Quiet at idle but when you're dropping the hammer you and everybody else knows it! And very tolerable in 5th gear on the highway.

      Worth the price

      Nice upgrade over stock. Easy installation with basic tools. Didn't even have to jack the car up. Loud when you want them to be and quiet when you don't. Zero highway drone. A bit pricey but worth it for the look and sound. I've had them on for a little over a thousand miles and have no complaints. 10/10 would buy again.

      Great mix of sound!

      When I was 17, in1969, I cruised around in a 1967 327-ci Chevy Impala Super Sport; my pals drove a 440-ci Dodge Coronet R/T, and a 383-ci Dodge Charger. We thought we were pretty tough stuff . This set-up on my 2008 Mustang GT recalls the very best of those period muscle cars: throaty rumble, mellow, fluted sound when accelerating lightly, and raucous, righteous roar when gettin’ it. And no annoying drone in cruising. It’s perfect. I couldn’t be happier. FYI: My buddy with a 2003 Mustang GT with cherry bombs is envious and says it sounds better, with less drone, than his friend’s GT with Dynaflow.

      FR500s on 2009 GT500

      I got this installed at a nearby shop for $125.00. Took an hour. People in the shop waiting area heard it start up before I did and they wouldn't stop complimenting the sound. Absolutely amazing sound, screams when you step on it, perfect gurgle idle, zero drone. Also I felt an increase in throttle response by letting her breathe. 100 would recommend.

      Great, but loud with LT's and no cats

      These are great, but very loud with long tube headers and an off road H-pipe. I think I like them enough that I'm willing to give up the LT's to reduce the loudness and keep these! I'll try to update my response afterwards.

      Best Sound For The 08 Bullitt

      Closest sound I have come to the movie car. Absolutely no drone. Easy installation. Less weight than the stock Bullitt mufflers. Tips same as stock Bullitt’s. Body was a bit messy but clean-up nicely with a 3m scratch pad, warm water and dish soap for those that are particular. Good buy.

      FR500S axle back for a 2006 GT

      Dee's muffler sound awesome. I'm happy they turned out the way they did after reviewing many videos going back and forth between many name brands finally settled on this set then they do sound very good. Only problem I had was with the Box they came in the packing material allowed the Mufflers to rub against each other resulting in one of the Mufflers stainless steel ends having scrape marks luckily after mounting the mufflers the scrape marks are on the bottom of the end cap which you can't see. Other than that I'm very happy with the sound that is now coming out of my Stang!

      I listened to a lot of sound bites on YouTube on MANY different Axle-Backs. I anted NO DRONE inside the car but great sound. These Hit the Nail On The Head!! They Look Great, Sound Amazing when on the gas, But only a slight rumble while cruising. Worth every Penny! Easy to install in my driveway with no jack. Installed by myself in 2 Hours.

      Just what I wanted

      This was the best decision ever! During Highway driving it's barely louder than series but when you get on it it sounds great. Nice deep rumble when idling and a little bellow on start up. Devilery was super quick and my questions were answered perfectly. Install just took 1,5 hours. For any future mods I will definitely come back here!
