Ready To Rock! These are the same exact premium mufflers that are included as original factory equipment on the Ford Mustang RTR designed and developed by Vaughn Gittin Jr. This RTR Axle-back not only looks and sounds great, but will also improve your Mustangs exhaust flow for an increase of up to 9 horsepower at the rear wheels. This system was made in close collaboration with Magnaflow Exhaust.

Loud Aggressive Sound. RTR worked closely with Magnaflow to achieve a very unique aggressive sound that gets rid of the robotic tones of the Coyotes variable cams for a clean and crisp consistent exhaust note with very minimal in car "drone."

Quality Construction. Manufactured from 100% stainless steel for long life and durability, this RTR Tactical Performance Street Spec Axle-Back Exhaust has free-flowing mandrel bent 3" tubing and chambered mufflers that feature 4" black finished tips and the "RTR" logo for truly aggressive styling.

Black Ceramic Coating. This RTR Tactical Performance Street Spec Axle-Back has been finished with a Black Ceramic protective coating that not only gives this exhaust a dark and intimidating appeal, but it also provides a high temperature thermal barrier for additional protection from the elements.

Lightweight. The RTR Tactical Performance Street Spec Exhaust is 14 lbs. lighter than the stock factory Ford axle-back system making it perfect for street, track and drag racers who are looking to shed unwanted weight in the pursuit of quicker times.

Direct Bolt-On Installation. Engineered to be a direct upgrade replacement, this RTR Axle-Back will easily bolt straight up to the stock factory piping without any modifications or special tools required for an easy installation.

Application. This RTR Tactical Performance Street Spec Axle-Back Exhaust System is specifically designed to fit the 2011-2014 GT Mustangs equipped with the Coyote 5.0L DOHC V8 engine.

    I got this muffler, litterly the same week CDC released it for sale. I've been looking for something that was nice and mellow with a deep growl. (aka the 80's 5.0 days) Upon scouring youtube I settled on Magnaflow Street series. But then I saw a vid of the RTR being tested #at the time the only vid available#, with these mufflers. They sounded awesome. So these became my new must haves. Finally got them orderd and installed... Started the pony up and heard a super deep growl that reverberated against the garage walls. Way louder then I expected them to be. So much so, that I wanted them off. I needed something quieter. But then I drove around for a couple weeks and realized, yeah they are louder than I wanted, but they sound pretty good. And they really do fit the 5.0 muscle profile perfectly. Now I feel like driving my car just to hear the things! What a turnaround that was. So the best way to describe them: -Take a Magnaflow Street and a Magnaflow Competition series and put them together. So litterly a straight-pipe with a chambered half. -very,very,deep growl sound, especialy between 1000-2000rpm. -but higher RPMs actaully get's a bit quieter. -sound is smooth, not tinny or ratty -let off the throttle and you hear a nice deep burble. During downshitts too. This has to be one of the best features of this exaust. So in conclusion: This muffler is NOT for you, if your looking for: -a quiet muffler -a super load muffler -a ratty tinny muffler, #like all the other straight thrus out there) This muffler IS for you, if your looking for: -deep,smooth growl -deep backfire -louder than stock by factor of 3 -listening to a V8 sound track while you drive As a side note: I've heard from a couple people that the exaust sounds like a proper V8 exhuast, not soemthign over the top, too much. And suprisingly, Crazy as it sounds. I've actually noticed a slight performance boost, the car seems to breath a bit easier. Smoother throtle through the range.

    I'm Ready to Rock

    I, like Cannonballer, purchased this exhaust just a week or two after it first came out. It was not available yet through American Muscle, or I would've purchased it here. I was fortunate enough to hear this exhaust in person on RTR #4 here in Charleston, SC. I was trying to decide between an MBRP exhaust and Borla, but as soon as I heard that RTR crank, i was done shopping. Incredible sound at crank. Deep, loud, rumble. Cold crank gives you 15 to 20 seconds of 8/10 loud, then it quiets down to nice mellow rumble. Hit the gas and it wakes up and sounds like a v8 should. What I love about this exhaust is that there is no rasp and no pop. The new 5.0, and 3.7 for that matter, are so poppy, and I hate that. This RTR eliminates that pop, even during deceleration (which by the way sounds absolutely wicked). When I think v8 sound, I think RTR up to roughly 2500 rpms. In fact, when I first cranked it at work, my workmate (a Corvette owner) said its perfect, nice low rumble, mellow, no pop. "Absolutely perfect" he said. But i say, not so fast... Now, i gave it 4stars because I want that sweet sound I hear below 2500 rpms to be there up top too. Unfortunately, its not. The exhaust quiets down dramatically while accelerating, the exact opposite of what I was hoping for. At Mustang Week 2012 Vaughn Gittin Jr. described it as a "robotic sound". Ummm, ok...if you say so. But more than anything it just gets quiet and that's a shame. Now, Vaughn Gittin Jr. also claimed that this exhaust netted a 9hp gain. Is it true? I have no idea, there is no way that I would feel 9hp. But what I did feel was smoother acceleration. All through the RPM range, the 5.0 pulls with no lag and throttle response is excellent. That's a testament to the car itself, but I do feel like this was increased by the exhaust. All in all, I really like it, but don't quite love it. If it kept its volume through the rpm range, it would be a perfect 5 stars.

    • Response from AmericanMuscle

      Just wanted to note, these RTR mufflers get rid of the robotic sound of the factory Mustang and I believe that is what Vaughn was describing. Hope this clears up any confusion.

    High quality, deep sounded muffler.

    I'm satisfied with this muffer, I had 4 sets of mufflers, so I'm not just saying because I'm having it. I had Ford Racing GT500 Style muffler, Pype muffler and Flowmaster muffler. RTR muffler: This muffler sound deep but not that loud, you feel deep bewteen 1500rpm-2000rpm. And the quality of this muffler is great. Overall, it worth your money. (Not to buy this muffler if you want a loud one.) GT500 Style muffer: This muffler is the deepest sounded muffler on a GT I've seen so far, so if you want deep sound, get it. And it's also cheap, but in good quality. Pype bomb: This muffer is REALY LOUD, I never knew that my car could be so loud by just replacing mufflers. If you're looking for a loud one, this is the right one to have. I don't hear myself talking in the car, specially bewteen 1750rpm-2250rpm. LOUD PIPES SAVE LIFES! Flowmaster muffler: Not that deep, not that loud, cheap and low quality.

    Magnaflow RTR Mufflers Exceeded My Expectations

    After listening to countless exhaust videos, I decided to try the Magnaflow RTR mufflers. I have a FRPP X-pipe and I did not want the raspy sound that the typical Coyote 5.0L exhibits. The idle sound is incredible with the FRPP ProCal II calibration. People cannot believe the motor is stock. There is no drone at 2000 rpm and the sound reminds me of a 1965 Ford Indy V8 on acceleration. I could not be happier with these mufflers. I did swap out the black RTR tips for a custom polish tip. I prefer polished tips.

    This axleback exhaust is great. I received it for Christmas, and had it installed a few days later. It is pricey for an axleback, but well worth it. On a cold start, it is loud then quiets to a deep rumble. It has almost no drone, a bit more than stock around 60-70 mph. Sounds like a V8 should, much better than the factory exhaust, and the black coating is an added bonus.

    Not Much Louder But Deeper

    The quality of these mufflers is excellent. They are made by Magnaflow and have a nice thick black ceramic coating that is show quality. They are also much lighter than the stock mufflers, weighing about 12.5 lbs each compared to 21 lbs each for the stockers. Installation was easy, all bolts and clamps use a 15 mm socket. You do have to cut or break off the tab and reuse the clamp off the old muffler. The only negative I had with this product is that I had to cut off about 3/4" of the exit pipe on the right side muffler. That is because it prevented the new tip from sliding on far enough to match the alignment of the left side tip. For some reason the right side muffler mounts slightly rearward as compared to the left side muffler. This in turn prevents you from sliding the tip on far enough. On closer examination, I think my right side muffler was manufactured slightly off. I really didn't like the idea of having to modify the muffler, especially at this price point. The sound has a very nice roar at start up and is deeper than stock. There is no more drone than what the stockers have so it's almost nothing. Overall, this is not a loud muffler but much deeper and that suits me just fine. The quality of the sound is way better than stock. BTW - my Mustang is a Boss 302 with the side exit quad exhaust. Overall sound might be somewhat different on a GT.

    This exhaust set sounds awesome! Such a deep growl that sounds mean when you rev the engine, when you can hear it that is. I was expecting them to be louder than they are. On a scale of 1-10 (10 being loud and 1 being silent) I'd put the stock exhaust at a 4 and rtr exhaust at a 5 or 6. If you're behind the car it sounds awesome. If you're in the car the sound of the engine drowns it out at around 3000 rpms. Still with all that being said I do love the sound and along with the easy install and nice looking black tips I recommend this if you're looking for a medium loud exhaust with a beautiful deep growl.

    Very Unique Sound!

    I purchased this axle back from a different site since I had a coupon. It is a great, unique sounding exhaust. Like nothing I have heard yet. First I had the roush axle backs, which sounded great with the stock exhaust, but when I installed high flow 3" cats, and the heartthrob kit with flowpacks, the exhaust just became crazy loud! Then I purchased this kit. It seems to flow a lot better, and is certainly more quiet. 1-10, 10 being the loudest, it's about a 5 or 6. It actually gets quieter as you go faster. I think if I had the flowpacks removed, it would be just perfect. There is also no rasp or popping like the roush. It sounds very smooth!

    Sounds Awesome

    i had questions before i bought that. soon as it arrives, i had no chance to wait so i put them on the car to hear what is sounds like. it was what i want... but also i suggest you to put boss302 side exhausts... also it is not so easy to install... That's why you should take it too muffler place...

    Nice and deep but a little quiet and muffled

    I had the Borla Atak axle back and it was beyond loud so it had to go. I also wanted something a little deeper sounding and not as raspy. I watched some videos of the RTR and it sounded pretty good so I decided to try them out and they are about half as loud as the Ataks. Plus with my white car and blacked out everything else I figured the tips would look good. Overall the sound is pretty good. Its very deep but has kind of a muffled sound inside the car. Outside the car it sounds much better. I read how people said it seems to get quieter as you get on it more and it does seem to. There is also a drone at 2000 RPM although its not awful and can be covered up by having the stereo on. The Borlas had no drone whatsoever. The tips are not welded on which allows you to adjust them unlike the Borlas which stuck out too far and couldn't be moved. The tips are also much smaller than the Borlas. Installation was pretty easy with a lift and 2 people but doing it on the ground would not be too fun since we had to remove the hanger brackets from the car to get the old mufflers out. It took about an hour to do the whole thing.
