    Review & Install Video

    Hey, everybody, I'm Justin with AmericanMuscle.com, and this is my detailed review of the Magnaflow Competition Catback Exhaust System, available for your 2015 and up EcoBoost-powered Mustang. You should be checking out the Competition from Magnaflow if you're after a top quality exhaust system made from 100% stainless steel, and one that's going to add a deep and aggressive tone to your EcoBoost Mustang. Now Magnaflow even goes a step further, and offers prospective buyers the option of grabbing this system in a more traditional polished or silver version, like we have on the table here, or for a few bucks extra, you can grab this system with black mufflers and tips for a totally different look. Magnaflow is without a doubt one of the most popular and well-known names in the industry and for good reason. Their systems consistently offer great sound, quality, and fitment. Now, guys, this is an exhaust after all, so let's talk about the sound you might expect with this thing, and as you heard with our sound clips, the Magnaflow Competition is going to deliver a deep and aggressive tone for your EcoBoost with the included Y-pipe. In fact, it's probably one of my favorites for the EcoBoost-powered S550. Now, even though the Competition muffler is traditionally one of Magnaflow's more aggressive systems, this thing is not going to be over-the-top. It's not going to be raspy. In fact, it's going to be very daily-driver-friendly and be pretty quiet while cruising on the highway. Overall, though, you're still getting some good volume, so I'll call it a solid three, maybe even a four out of five on my one-to-five, or one-to-wake-the-neighbors scale. Breaking down the construction with the Magnaflow, guys, here's what you can expect: durable 409-grade stainless steel throughout, including the 2½" mandrel bent tubing, the included Y-pipe that does utilize the 2¼" factory connect, or will work with any aftermarket downpipe as long as it includes a 2¼" connection. You're also getting the Competition series mufflers here from Magnaflow, and finally, their large 4½" tips, again, in polished or black, your choice. I do want to point out that to my knowledge, guys, Magnaflow's one of the only companies offering a large 4½" tip. Most of the other offerings I've seen are basically 4". I prefer the 4½" tip because I think it looks much better on the S550, just fills out those bumper holes perfectly. Now, as you heard me mention earlier, guys, you do have a couple of options when it comes to picking up the Magnaflow. For instance, we do have the more traditional polished version on the table here. This thing's going to set you back just north of $1,000, or for a couple hundred bucks more, you can grab it in the black powder coating with the mufflers and tips here if that's the look you're after. This system is made in the U.S.A. and, of course, it is backed by Magnaflow's lifetime warranty if you should ever need it. Now, one small nitpick here with the Competition series, guys, is that the materials, for the price you're paying, I would have preferred to see the 304-grade stainless as opposed to the 409 that they used. It really isn't going to affect the performance whatsoever, but it's something I just wanted to point out. The Magnaflow does feature a bolt-on or clamp-on design, so no cutting, no permanent modification needed whatsoever, so for you guys, expect a very easy one-out-of-three wrench job on my overall scale of difficulty. Now, removing that factory exhaust can be a little cumbersome since it is one piece can be a little heavy, so while not needed, an extra set of hands would certainly make your life a whole lot easier. When it does come time to bolt this thing up, though, get some basic hand tools ready. Basically, a socket set, a few wrenches is really all you're looking at here, guys. You're only going to need about an hour or two in the garage or driveway to get this thing bolted up. And, of course, all of your work is done underneath the car, so make sure you have your jack and jack stands ready to go, race ramps or a lift if you're one of the lucky ones. All right, guys, armed with those sound clips and my review, hopefully, you have a better idea of what to expect with the Magnaflow Competition and if it's going to be the right system for you and your EcoBoost. Now, what I can tell you is that the Magnaflow's built extremely well. It's going to offer some nice, well-rounded sound with a good amount of volume. So be sure to learn more about the Magnaflow options for your EcoBoost Mustang, right here at AmericanMuscle.com.

    Add Horsepower. Stop denying your high powered 2.3L EcoBoost Mustang the power it deserves by keeping that factory exhaust system. Enjoy more horsepower and torque with a Magnaflow Competition Cat-Back, by reducing back pressure and giving your Mustang a free-flowing exhaust.

    Aggressive Muscle Car Sound. Give your EcoBoost Pony a deep, aggressive rumble by adding this Magnaflow Competition Cat-Back. This premium quality exhaust features free-flowing, straight-through mufflers that increase power and give your 2015-2019 EcoBoost an unmistakable muscle car sound.

    Application. Made to be a direct bolt on, this Magnaflow Competition Cat-Back Exhaust will bolt straight up to the factory Mid Pipe without any extra modifications required on the 2015-2019 EcoBoost Mustang without the Active Valve Exhaust.

    How does this exhaust compare with the Borla ATAK in terms of sound? I am looking for a deep and smooth tone.

    • The Borla ATAK is one of the loudest exhausts offered. In terms of how loud it is, I would rate it an 8. The Magnaflow is closer to a 5 in terms of how loud and aggressive the exhaust is.

      Way better than stock

      This is my first mod and i couldnt be happier with it. Its loud but not obnoxiously loud has a deep agressive tone. Im not very experienced with cars but me and my brother who also isnt very experienced installed it pretty easy. The hardest part is taking off the stock exhaust but after that its easy took us about an hour. Mufflers are big and aggressive looking. This is how a v4 stang should sound.

      This is great, when you start it up it has a nice growl now, it is loud when you need it top be and quiet when need it to be. I have a convertible and it does not get so loud it ruins the ride, but it sounds very tough now. The pipes look great out the back end as well.

      Just what I expected

      I wanted a deep tone and a bit of rumble. Something refined but said "I'm a sports car!" I got exactly what was in my head. I will say it's louder than I thought, and because of that, you may want to consider the MF Street vs. Competition. The only time it gets annoying is at 70 mph and I have to take a phone call via the bluetooth in the car. Folks can certainly tell I'm driving! :) I love the tone, sound and decrease back pressure. I gave 3 Start for "Bank For Buck" as this is a pricey kit without having 304 SS. Note of caution to 15 and 16 owners, you may see some blue smoke at idle after installation. This is caused by a decrease in back-pressure and a faulty PCV valve. Check TSB 15-0192. Regardless you should get that taken care of regardless if you do a tune or exhaust. Essentially the PCV valve is either seized or defective. A tune, downpipe or cat-back exhaust will cause you to hit this defect if you have the old PCV separator.

      Better than expected

      My eco sounds amazing now. The videos don't do enough justice. It's also a tad bit louder than I wanted but you can manage it depending on how you drive. Also if you take it to a muffler shop make sure to have them weld the pipes a couple of times at the connection points, they told me sometimes they become lose and even get lost on the highway when they get hot and expand.

      Noise maker

      I was contiplating between this and Borla for months. Borla was a bit more so I ended up getting the Magna flow. It's pretty quiet, but could definitely tell the cat delete. But I'm comparing from my last 2012 gt with Roush axel back so not really equal comparison.

      Deep Growl

      2015 Mustang Ecoboost. Ever since I put them on I've been having white smoke come out the back when idling. Going to invest in an after market oil seperator and see if that fixes the problem. I know the smoking is a known problem for the ecos, and is common with new pipes... I forget if I ever got the recall fixed. Instead of using the clamps that came with the system, I paid a shop to weld the system together. I recommend doing the same. After weld; wayyy better fitment. Deep tone, I can hear the turbo whistling out the back, cold air, and tune. Paired this system with an off road downpipe and holy smokes... My lil beast is coming together. This system woke her up.

      Giddy UP! Easy Install and it Sounds Great

      Installed on a 2016 Ecoboost and I'm LOVING it. The sound is good - when you punch the throttle your presence will be known. But its not too loud for my daily driver, or my quiet neighborhood. I was worried the car might sound like a loud lawnmower since its not a v8, but it has a nice throaty sound! I'm happy with it, it was just what I was hoping for. I don't think the videos I've heard, including the one I made, really capture the sound correctly. Not sure why. But it has a nice throaty note now. Install was super easy! Quality Build. No adjusting or tweaking was needed. (as a FYI, this system install was a Huge Huge difference from the install of different manufacturer that was done the next day on another 2011 Mustang, Had to spend a good 30 minutes trying to get that system tweaked so it fit properly, and the quality of the pipe work was just not the same as Magnaflow!) The quality of work/bends and construction of this system far outweighed the other manufacturer, and this system was built and spec to fit like a glove in the 2016 Ecoboost. If you are on the fence with this system or others due to price, just pay the $. The quality here is evident when I had the 2 systems side by side. Removal of old system and install of this was an hour tops.

      Deep sound

      If you're not a fan of deep tone than this thing is not for you. I had a little problem while installed this at a shop. The tips fitted awkwardly but we were being able to solve the problem. Overall very good quality, I'm happy with the sound and the look, though the tone is too deep it could get annoying time to time when you were in traffic. Ps: the installation fee was $80

      Deep and loud but never noisy.

      I was extremely worried that this would be too loud and almost bought the Magnaflow Street Catback. Honestly, its not as loud as you or your neighbors would imagine. The loudest it gets is during a cold startup, especially in a small garage, but again it's not THAT much louder than factory. The tone is what differs the most. You will hear a subtle purr while idle, and an audible growl during acceleration in the cabin. Of course, the looks are top notch and the install was easier than removing the factory exhaust. I got it done with a jack and jack stands, and I've never done maintenance on a car before this. One thing I would recommend is taking off the four bolts holding up both factory mufflers near the rear bumper, and resting the rear end of the exhaust on the ground; it will be easier to slide the resonator end out of the factory down pipe, which was the most difficult part for me. Anyhow, get this if you are stuck between the comp and street series, as long as you're not afraid to be heard.

      So glad I bought it!!

      It definitely doesn't sound like a V8, but man I am happy!! I wanted this to be my sixth Mod, but I could stand hearing the stock exhaust. The only thing about it, is that you MPG will be at least 16MPG.. And 11MPG if you want to keep pushing it to hear it lol.. I'm enjoying every second of my car now. I though I was buying the EcoBoost to save gas, But now I don't even car about it lol.. Before I was getting at least 25MPG.. I'm giving you the go ahead!!! You won't regret it!! P.S I gave it a five star, because it's the only exhaust out there that gives you the aggressive sound for the EcoBoost.. ((You won't have to look elsewhere to find it))

      Super easy install

      Notable difference when throttling. I carries a deep note outside, but also a steady hum can be heard from the interior. This may get annoying over time...or not ;) Im an old Jeep enthusiast and used to working on my own vehicle, so anybody with any mechanical ability will find this install extremely easy. The install took about 40 minutes working alone in a shop with a lift. I paid $6 for the stall and only used 1 socket. This was a super-easy install with NO cutting. Hint: remove the rear mid-section bracket holders when removing the stock pipes. It's easier. Highly recommended.

      Great looking and aggressive deep sound

      I have to say that I chose the right product. As we all know the ecoboost mustang's 4 cylinder turbo sounds too smooth and weak so definitely the exhaust has to have a deeper tone to cover the turbo sound. Magnaflow competition exhaust is clearly a very good choice. It took me about 1 hour to finish changing, the product has a very fantastic looking on the car also. As you start the engine you will hear a very deep and strong sound coming from the back of the car, it really sounds much better than the stock exhaust, and also lighter too. I love the put to "S" gear as the rpm will goes higher and the sound is more attractive. Now, if you're looking for something loud and crispy, you may have a look at Borla Atak or Flowmaster outlaw, because Magnaflow sounds very deep, as I would say this is one of the most "V8" sound for ecoboost. People may ask me the competition and street which is better, well, the competition is louder of course, and sounds thicker I guess. Personally speaking competition is loud but not noisy, the volume is just enough to hear. Overall, I highly recommend this product.

      Deep Tone Screams When You Step on it!!!!!

      Night and day difference from the stock exhaust to this Magnaflow Competition Catback. I can't speak on the installation difficulty as I had a shop do the install, but they told me it took about a couple of hours to install. This exhaust has a MUCH deeper tone than stock when idling. It's not over the top loud in my opinion especially when cruising along but when you step on it, it lets you know its there! Some drone when hovering around 2k RPM and I know some folks will say any drone is bad but it's not loud to me at all or irritating in the least. You'll notice it more when in Sport mode as it keeps the RPMs higher but not so much when drive mode is normal. If this sounds concerning to you, go with the Street Catback as those mufflers probably eliminate this. The competition model is designed to be loud, and when combined with a cold air intake that vents to atmosphere, the sound is incredible. Overall, I'm very satisfied. Always heard good things about Magnaflow's exhaust kits and this validated what I've heard. Price is right about where a majority of exhausts cost for the Ecoboost model and if you're looking for more bass in your exhaust as well as one that sounds great when you step on it, look no further!
