Work with 2013 GT? I am getting a 2013 Mustang GT Premium. Does this work for the 2013 as well, or is there a new product coming soon? Looking at the FRPP website their's works with the 2013's now. Also, does this come with the actual procal tuner, or just a voucher for a dealership to use their own and I would never get a tuner?


  • Yes, this Power Pack Upgrade Package will in fact work on the 2013! We are updating our site as we speak to reflect that! You will at first receive just a voucher for the ProCal. Due to multiple power-train calibrations, you have to registration online with Ford Racing and then you'll receive the ProCal calibration tool after purchase. Hope this helps!

Will this tune work with a cold air intake? Thinking about the Ford Racing Power Pack, but am wondering if the tune will work if/when I iupgrade to a cold air intake such as the Airaid?


  • This Power Pack would not work with an aftermarket CAI that requires a custom tune as Ford doesn't support other manufacturers CAI's. If you plan on going with an aftermarket CAI you would want to look into a tuner like the SCT or Diablo models.

Is this the same kit as Ford part # M-FR1-MGTB? I ask because you list the mufflers as Ford Racing GT-500 and Ford Racing site lists them as "2011-2012 Mustang GT - SVT Muffler Kit (50 State) M-5230-MGTCA1" . Now they might be the same part but I just want to know.

    The product is all there besides the pro cal tuner which you have to reorder on the ford website. The exhaust itself has the perfect tone and loudness. Also the drone is almost non existent on the highway.

    Better Than Expected!

    Enough reviews have been written that I cannot add much more. I didn't really expect as much performance response, through all RPM range, as this little tuning add-on has provided! I agree with one really long review/novel size review (I read twice and made my decision), the exhaust note is PERFECT. Not too loud; I can listen to may SHAKER (w/Crutchfield upgrades) while cruising through town with the windows down, listening to that wonderful burble; or coming home from work, downshift to lower gears when I arrive in the neighborhood to pleasantly announce "I'm home" with the slight pops that make it out!

    Nice Upgrade

    Delivery of the GT500 exhaust, air filter and oil filter arrived 3 days after purchase which was a Friday. Ordered Procal that night and received it the next Tuesday. Wednesday tuned my vehicle my self with the procal, pretty easy but I did have to run jumper cables from wifes car to mine in order to have the necessary voltage. Drove it after tune and yes you can tell the difference, more low end torque and better acceleration. Then installed the GT 500 mufflers in my drive way with help(highly recommended). Im not a mechanic and neither was the help. But it took us about 2hrs total. The driver side muffler is a pain to install, the passenger side was pretty easy. But after a little frustration and a rubber mallet it all went in pretty nice and centered, the driver side pipe sticks out about a cm more than the passenger side. I will fix that tonight. Normal gas milage driving to work was 23MPG, this moring it was 26MPG. So nice gain there. And yes the exhaust sounds awesome. Final note I was going to have ford do all the work. The quoted me $500 for 4hrs of work. Needless to say I went straight to youtube.

    This should be any Mustang enthusiast first mod! Ordering from American Muscle was super easy and the install was pretty straightforward. You need to pay careful attention to the procal installation as this was the trickiest part of the power package but definitely worth the effort! I could of ordered this through other vendors but found AM to have the best price and customer service!

    Ford Racing Power Pack

    Great value for the money. The mufflers and tuner come out to $300 each and that excludes the K&N filter & oil filter. Compare that to the Flow Master American Thunder that's high $400's and other tunes that are quite a bit more. The exhaust sounds great at cold start up and WOT, but are as quiet as stock and cruise speed and if idling for a while. The PROCAL tune is an amazing value! It changed my Mustang for the better. I noticed more aggressive throttle response, the car pulls harder and greater responsiveness. Paid $85 for dealer to install which is worth it to not void warranty. Since I have a Rouch CAI, I ended up selling the K&N on eBay.

    I own a '14 GT Convertible w/6MT and 3.31's. I wanted something with a little more "sound" and "oomph." This package hit those spots well. The nice deeper rumble when I start the car is great, and it's "quiet" when I need it to be (neighborhood, or when I have the top down and the old lady in the car) and roars nicely when I want to play. The tune made the car come a bit more "alive", and I also think I picked up a mile or 2 on the mpg; however, if you really want a pin in your seat experience through all gears, think 3.73's are the way to go (....maybe next year?). I ordered from AM (love all the videos and the reviewers posts) and had it shipped direct to my dealer. I then stopped by the dealer once in, took the procal sheet home and ordered it, and once the procal arrived at my house I made an appointment to have my dealer install it all. Labor was $250, and it took him ~2.5 hours (includes oil change, axle backs, change air filter, tune, and re-box old stock mufflers). Anyone need a set of stock mufflers with ~2500 miles on them?

    Great Power Pack!

    I've first had the Roush exhausts mounted on my 2013 Mustang GT and I really love the sound of these exhausts, but the're too loud for The Netherlands when I take my Mustang back end of this year. The Ford GT500 exhausts are more quiet (stationary in the garage, but also during normal driving) than the Roush exhausts. They still give more sound esp. at WOT than the stock exhausts. Note: I've already sold my Roush exhausts on Craigslist. I was impressed by the Ford Tune: it gives a lot more torque ar low rmp's and also gives a better mileage (about 2 mpg). The wheels spin much easier now when I hit the gas after a standstill. Overall this is a very good kit for the money.

    Just what the doctor ordered!

    The FRPP basically "fixed" any disappointments I had with my '14 GT. First off, the GT500 axle backs sound mean- but not obnoxious. Turning the key on a cold start always brings a smile, there is a nice grumble during acceleration, but things stay "civilized" during highway cruising. IMO, these mufflers should have been included in the Track Package from the factory. The only drawback was damage to one of the exhaust tips. The packaging isn't sufficient to protect the tips, and one of mine had a nasty ding on the top of the lip- which took about an hour for me to straighten. I should note the packaging seems to be done by Ford Racing- not AM. The tune absolutely fixes the car (again, this should be the factory tune for the Track Package, IMO). I feel a lot more torque down low, and- most importantly- the accelerator acts the way it should (i.e., immediately and consistently). The result is the shifts through 1st, 2nd, and 3rd become much easier, smoother, and more satisfying- AND there is no more issue with stalling when I back up my driveway. Finally, it really makes 6th gear more practical (no longer have to shift to 5th for passing on the highway). Registering the Procal is easy, and it arrives the next day. I installed the mufflers myself (bending the forward mounting rods up slightly at the ends makes installation much easier- but doesn't affect final mounting location). To keep the warranty, I had my dealer install the tune (they charged $232- be sure to be clear on how much the install fee will be... it takes about 20-30 minutes, but my now former dealer charged me 2 hours labor). All in all, the FRPP produced the sound I was looking for and the street performance a 420hp car should have.

    should be stock

    My first mustang (2014 GT convertible) and I was very impressed with the handling and performance of the car. One thing that annoyed me was how quiet the car was! I would pull up to cars at a light and i could see them lowering their windows to hear the 5.0! Well they were in for a surprise because the original pipes are Lincoln quite! So being in my 40'S I Didn't want to stand out and scare little children so i did many many hours of research For the perfect axle back. My first choice were the American Thunder from flowmaster. I feel it's the perfect sound for this V8 but when i saw that i can get a performance kit from Ford for the same price i went for the power upgrade! The GT500 axle back are perfect. No drone when cruising and just the right tone when accelerating and at idle. Not the best looking exhaust tips but better than stock ones. The tune....WOW! Still have my warranty and the car feels more responsive! Highly recommend this power pack for those who aren't hardcore sound and power freaks. This really should be stock set up for the GT's. American Muscle was amazing! I live in Canada and received my order within a week!

    Ford Racing Power Pack

    This is the best addition to 2013 & 2014 Mustang GT owners that don't plan to track their car all the time. The throttle response is improved and the torque in the lower RPM range is really noticeable. My gas mileage has improved as long as I keep my door out of it which is hard they way the GT500 mufflers sound. American Muscle is fantastic the product arrived within 2 days and was really easy to install. In fact if anyone near Atlantic city that orders this kit and needs help just let me know.

    Big difference in both sound and feel

    The lower rpm range and soundyou of my 2011 GT was somewhat disappointing until I purchased the frpp powerpack with GT500 mufflers! Have gotten many compliments on the exhaust note and can feel a difference in the car with the power pack installed, and still keep my warranty after paying Ford a $50 install fee for powerpack! !! Can't beat that for the price... (I installed mufflers/filter myself, but the procal needs to be installed by ford dealer to keep warranty). All in all, extremely happy with my purchase

    Easy to install. The GT500 mufflers are perfect for being quiet in a neighborhood, but increase volume north of 2000 rpm. I don't know why Ford bothers with the K&N since they have proven to loose HP on dynos. Oh yeah, and FRPPs procal registration website drastically needs an update!

    Great Bang For Your Buck!!!!

    For the price you cant beat what you get with this power pack. The GT500 mufflers sound sweeeeeet! I had shopped around for axle backs for some time and these offer the best sound and are one of the least expensive. Totally changed the tone of the exhaust without making it a whole lot louder. I drive in and out of my apartments at 5am and these are great when you want to sneak out and really open up when you step on it. The tune might not be the most aggressive out there but it does take care of two of the biggest issues i had with the stock tune, major throttle response lag and slow automatic shifts. The low end torque got a boost and it picks up a bit faster. I'm also seeing a bump up of 2 MPG, 21MPG mostly highway. Very satisfied considering my mustang is a daily driver.

    Great upgrade, incredible sound!

    I can't speak for the increse in performance yet, but I need to share how happy I am with the way those new GT500 axle back sound. More aggressive while you play with the shifter, same sound levels on the highway. I liked my car, now I love it! I can't wait to see what improvements the tune will add. I had to call Ford Racing' 800 line since the voucher code provided in the box had already been used. Teh agent quickly provided me with a new code, no questions asked. Fast and efficient, the way I like it!

    Noticeable Improvement in Performance and Much Better Sound

    I purchased a 2014 GT Premium Coupe w/6AT, Brembo brake package, and 3.15 rear. As other reviewers have mentioned, I wanted more response and more throaty "sound". The FRPP was recommended to me after I expressed concerns about warranty coverage--nor did I want issues with my dealer. The ProCal tuner delivered crisper shifts in Sport Mode (6A remember) and noticeable low end push once past 1500RPM and improved top end too. Ford Racing Parts personnel were very responsive in sending me the car-specific tune once I received the package (they provided 1 day mailing which was impressive)--and offered great advice--in fact directed me to AM to buy package.) I expect the KandN filter contributes to performance at the margin (the competition oil filter is a nice perk that will be installed at next oil change). The big difference that others notice and I love is the low bass rumble when at idle and then the progressively louder snarl as you go heavy throttle up the gears--no comparison to the stock sound which was too mellow. Turns heads on downshifts but can be almost civil when one needs to avoid undue attention. I can't tell if MPG has improved or not (I normally get 22-23 in commuting) because I'm enjoying the playing with throttle in Sport mode way too much! Dealer agreed to install package and support it under warranty (after a little negotiation) with 3 hour labor estimate at $120 rate. But it was worth it - and dealer service people were pumped when they delivered it to me and said "start her up!". I am very pleased. This is my 3rd Mustang (previous was 1996 Cobra and 1990 GT Coupe) and the best yet in terms of performance, comfort, and style.

    Setting a new baseline

    As stated by some other reviews, this should be how a stock mustang sounds and handles/reacts. That being said it would be great if the mufflers were a little bit louder at stable speed, because they're *really* factory quiet when cruising (and quite close when warm idling) which is kind of a let down. On the other hand, they are quite loud on acceleration, maybe a little too much because even quite smooth acceleration make it seems like you try to break some record. But hey, no regrets at all here, just nitpicking. It's worth noting that cold idling is awesome... like... really awesome. Also the included tune is nice for city driving and highway overtaking without downshifting. A real plus for daily drivers.
