Review & Installation Video

Review & Install Video

Hey guys, I'm Justin with, and this is my detailed review and install of the Magnaflow MF Series Cat-Back Exhaust system, featuring the dual same side exit configuration which dumps before the passenger side rear tire, available for your 3.5 liter EcoBoost-powered 2015 and up SuperCrew or SuperCab F-150. In this video, we're gonna cover three big topics. We're gonna talk sound you can expect here with the Magnaflow MF series, we're gonna talk about the materials used in this system, and then finally, we're gonna do a quick little walk through of the install itself. And honestly, to the most you guys out there, it's gonna be a one outta three wrenches on the difficulty meter, nothing too crazy here, so we'll have a little more detail coming up on that later on. The Magnaflow MF series Cat-Back here is gonna be a great choice for the newer EcoBoost owners out there who are after a really well-made system from a quality brand like Magnaflow. You want just a little bit more noise both inside and outside of the truck, and finally, and maybe more importantly, you want the very cool dual same side exit configuration that will dump before the passenger side of your tire. So again guys, this is just gonna be for someone who wants a little bit more sound and maybe isn't concerned with being the absolute loudest truck on the block. So with all that said, let's take a closer look at this Cat-Back. Magnaflow is definitely one of those companies that's known for making some pretty solid stuff overall, using 100% stainless steel for the most part, all of which is gonna fit great and produce some pretty well-rounded tone. Now the MF series that I have here certainly checks all of those boxes, and I think you'll find that this is just one of many different offerings for your EcoBoost-powered truck here on the site from Magnaflow. This particular option, again, that I have in this video is that very cool dual same side exit that will dump before the passenger side rear tire, much like the older SVT Lightnings. They also offer the same exact system a little longer that will dump after the rear tire, a little bit more traditional of a configuration. They also have the very popular dual split side exit system, and just a more traditional single side exit system as well. So again, as you can see, guys, they have just about something for everyone. Now, all these systems I just mentioned are gonna utilize the same MF series muffler here, guys. So don't expect a huge variation in tone from one system to the next. Instead, it's really just gonna boil down to what kinda look you're after with your exhaust, and how much dough you wanna spend. As far as the tone, you can expect when installing the MF series here, well, you guys heard the sound clips, ultimately you can be the judge, but in my opinion, guys, this is one of my favorite exhaust systems for the EcoBoost-powered trucks and here's why. You're getting just a little bit more tone over that factory system. Again, these are turbo V6 engines, a lot of us guys don't wanna really advertise that too much. We know it's not a V8, it'll never sound like a V8. So if you can get something that says, "Hey, I'm not stock, but at the same time not gonna drive the family crazy," well, again, this is gonna be a great system for you. Breaking out the wake the neighbor scale, I'm going strong, two out of five here, guys. Again, just slightly louder than your factory system. Interior noise is practically nonexistent. So a perfect choice for a daily driver or family hauler that does see a lotta road trips. But let's talk about how Magnaflow achieves that nice, deep tone here with their cat-backs. And as you might imagine, a lot of it's gonna come down to the MF series mufflers that they incorporate with a lot of their EcoBoost or truck systems in general. You're gonna find a perforated tube inside of the actual muffler itself, and also a combination of a stainless steel wrap and an acoustic material that does a great job of rounding out the sound with their systems. But again, you are getting that nice, deep, rich tone with the Magnaflow here, I like to call it a nice, full-bodied tone. You're not getting the high-end or raspy pitch with the Magnaflow systems whatsoever. So if that's what you're into, this is a great choice. You're also getting that straight-through muffler. Again, you might see a little bit more performance out of the truck with this system, but ultimately when you're adding a cat-back to your newer EcoBoost F-150, you're mainly making a sound and an appearance upgrade more so than a performance upgrade. Bringing down the fine details here with the construction, guys, you're gonna find three-inch mandrel bent tubing. It's a smaller system overall, as you can see. And of course, the three and a half inch brightly polish/cut tips, they look awesome when installed on the truck. Again, I really dig this style of system. You're looking at 409 grade stainless steel here throughout. Again, do a great job of reducing corrosion, help keep the price down slightly compared to those more expensive 304 grade systems. Everything's made in the U.S.A., and everything is backed by a lifetime warranty. On the topic of price, guys, I think you'll find a lot of the Magnaflow options here on the site for your F-150 are gonna fall on the higher side of the mid-level price range. And what does that mean to you? Well, these things aren't gonna set you back as much as the Corsa stuff or the Borla stuff for instance, but you are gonna be dropping just south of 1,000 bucks, which still is a good chunk of change, I'll give you that. You get the factory and you're getting some pretty solid materials and an A+ plus build quality. Now, if you really like the dual same side exit configuration but you have a really tight budget, MBRP's gonna make a few systems that'll give you this similar look, not gonna be as nice as the Magnaflow, but it'll definitely get you there if that's what you want. As I mentioned at the top of this video here, this is gonna be a simple one outta three wrenches on the difficulty meter when it does come time to get everything bolted up. In fact, removing your factory system, getting this new guy in place here, only gonna take you about an hour or two using some basic hand tools. And by basic, I'm talking 13 and a 15 millimeter socket, cordless impactor air will certainly help the job go a lot quicker, but overall, you can do this thing with basic hand tools on your back if need be. Now this is a SuperCrew or SuperCab specific truck, so go ahead and remove that factory system first. Get the new Magnaflow in place in reverse order starting from front to back, and you should be making noise in no time. As an EcoBoost owner myself, I really enjoy the Magnaflow MF Series Cat-Back based on the sound alone. Now again, a lot of us V6 owners don't exactly wanna crank up the volume like the V8 truck owners out there, and if that does sound like you, then I really do think you'll enjoy the system. Pair that with the quality build, the great materials, and the very cool dual same side exit configuration, and again, you get a great system if you don't mind spending close to 1,000 bucks. So that's my review of the Magnaflow MF Series Cat-Back, which you can find right here at

Free Flowing Exhaust. When replacing the factory exhaust on your 3.5L EcoBoost F-150, make sure you add the ultimate exhaust to your truck. If you're unsure what to get, that is where Magnaflow comes in with their MF Series Cat-Back Exhaust. This MF Series Cat-Back reduces back pressure and gives your Ford truck a free-flowing exhaust, that will provide an increase in horsepower and torque that you would want at the rear wheels. On top of it all, the unique dual same side exit gives your EcoBoost the old school SVT Lightning styling that will set your rig apart from the rest of the crowd.

Smooth, Deep Tone. Give your F-150 the smooth, deep sound it deserves with the Magnaflow Cat-Back. The included MF Series Muffler feature a free-flowing, straight-through perforated stainless steel core. The muffler is filled with a stainless mesh wrap and acoustical fiber to deliver that smooth, deep aggressive tone.

Magnaflow Quality. Proudly Made in the USA, this MF Series Cat-Back is constructed from durable 3 in. diameter mandrel-bent 409 stainless steel tubing for its strength and corrosion resistance. This exhaust system features a single inlet/dual outlet muffler, that connects to a pair of brightly polished 3.5 in. stainless steel tips that exits before the rear passenger tire for an impressive look and sound.

Bolt-On Installation. Magnaflow designed this Cat-Back System to be a direct bolt-on install using the factory hanger locations. You will only need access to basic hands tools, as the system does not require any welding or cutting. The kit includes all of the necessary hardware for a painless installation.

Application. The Magnaflow MF Series Dual Same Side Exit Cat-Back System is specifically designed to fit on all 2015-2017 SuperCab and SuperCrew F-150s powered by the 3.5L EcoBoost engine. Does not fit Regular Cabs and Raptor models.

    Awesome magnaflow exhaust

    This exhaust was a breeze to install minus it not fitting the 6.5ft bed. I made this system work anyway. Just a little extra pipe and I was good to go. It really adds a sporty look with the side exit before the rear tire. Definitely more of an aggressive sound too. One of the best you can get out of this V6. Very happy with this exhaust and American Muscle with great service and support.
