    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.

    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.

    do these have the ford logo on them and are allowed in all 50 states

    bhoff55

    • The Ford Performance FR500S Axle-Back Exhaust (05-09 GT, GT500) will not have the Ford logo on them. This is however CARB legal for all 50 states. However if you have questions about restrictions, contact your state DMV for further information.

      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!

      FR500S Axle-Backs

      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!

      fr500s

      This is the second axle back exhaust that I have installed. Installation was easy, takes a little over an hour with the car on ramps. The finish is not the best but overall I am pleased with the look. Most important the exhaust note is exactly what I was looking for. It is loud on start up, and you can hear the car when driving, but on the highway at around 1700 to 2000 rpm there is no drone and can hardly hear anything except a slight tone. Very happy with these mufflers

      FR500S KR's - "Best of the Best"

      I read through so many reviews and listened to countless sound-clips of Mustang axle backs. I can honestly say that I did my homework on selecting the perfect axle back. First, the quality of FRPP is unmatched. The construction, welds, and fitment are impeccable. Second, the overall sound being produced is a deep, throaty, true muscle car roar that is even more evident when you go WOT. Otherwise, it produces an incredible low rumble with absolutely "ZERO" drone at start-up and at cruising. Lastly, once again American Muscle comes through. They provided me with a military discount on my purchase, which was the best price anywhere. Thanks American Muscle!! In my opinion, this is hands down the best axle back on the market for a 05-09 Mustang GT or GT500. FRPP KR’s are Best of the Best!! - Brian

      NO BETTER SOUND ANYWHERE.

      1st, , it's not a complicated install, take it to a less expensive shop you trust. 2nd, sounds amazing. I don't know why I waited to do this. The sounds creates a dramatic feeling when accelerating, it feels like you're moving faster, obviously not real, but if feels that way. 4th, sounds is so perfect and 0 drone if cruising, and not loud with windows up. 5th, honestly, its the best sounding muffler Ive ever heard on any car anywhere, muscle, pony car, import, truck, anything, really. Don't think. Don't look at anything else. Get it.

      GET THESE! I'M SERIOUS!!

      Holy smokes! Put these on and you have a different car. First, the most important note: NO DRONE! ZIP, ZERO, NADA. Enough said on that. Second, my Mustang GT now sounds like a race car! The only time you really get any noticeable increase in sound in the cabin is when you 'get on it' and then -- it's BEAUTIFUL! Go easy on the throttle and you won't disturb the neighbors... You want to turn some heads? Just up the RPM's and you get a growl that lights up your heart! SO glad I got these! Did I say ZERO drone? yes, ZERO.

      Best sounding axle-backs

      From the stock exhaust to long tubes, high flow midpipe I've kept this axle back, it sounds great and doesn't suffer the constant drone other axle backs have.

      This is how mufflers should be

      I own an 05 GT and an 07 GT500. I have this exhaust on both now and it is perfection! It turns heads when you get into it but remains quit at cruise. Both cars are convertibles and I swear thsee are quieter at cruise then the stock. NO DRONE! NONE! NADA! I love the roar when you hit the gas and believe me people notice, but only when you want.

      Perfect sound and improved perfromance

      The sound of these is perfect. Loud enough when you get on the gas, but won't make you sound like a 17 year old trying to tick off the neighbors. I noticed better throttle response as well. It took a few hours to install, only because I didn't use a lift and reaching around the stock mufflers to unbolt the hangers was a bit tricky. Installing the new ones was easy, because they are way smaller. Just installed the Airaid CAI Bama X4 tune and the car is really coming alive.
