Review & Installation Video

Review & Install Video

Hey, everybody. I'm Justin with, and this is my detailed review and install of the Flowmaster Outlaw Series Cat-Back Exhaust System, available for your 2015 and up, 2.7-Liter EcoBoost-powered F-150. All right, guys, in this video, I'm gonna break down the sound profile you can expect when checking out the Outlaw Series Cat-Back for your EcoBoost. We're gonna dissect the construction and materials here with this system, and then finally we'll take a quick little walk through of the install. And for the majority of owners out there, one out of three wrenches on the difficulty meter. There is a small amount of cutting with some owners out there, but I will talk about that more in detail later on. The Outlaw Series from Flowmaster is without a doubt one of their most aggressive offerings and probably one of the most aggressive cat-backs available in the aftermarket. So with that said, this is without a doubt gonna be for the EcoBoost owners out there who wanna be heard and want a whole bunch of noise from that turbo six banger. Now, this is also gonna be one of the only aftermarket cat-backs available that will give you some options when it comes to configuration, thanks to the included piping from Flowmaster. You have the ability to do this thing as a Dual Split Side Exit or a Dual Split Rear Exit, depending on your mood. So with all that said, let's take a closer look. Since this is an exhaust, let's talk sound. First and foremost here, guys, and as advertised, the Outlaw Series is an absolute screamer with the EcoBoost trucks, an easy 5 out of 5 on my 1 to 5 or "One to wake the neighbors" scale. You're getting a ton of noise, a ton of turbo noise, a ton of engine noise, all the noises basically here. And as loud as this thing is on the outside, it's equally as loud on the inside. Some of you guys might be into that, others maybe not so much. Now, if you are the type of truck owner out there who takes a lot of trips with the family, long road trips, things like that, this one might drive the family a little crazy after a few hours on the road. So if you are looking for a slightly more quiet experience inside the cab, but you wanna stick with a name like Flowmaster, be sure to check out their Force II or maybe even the American Thunder. All right, guys, so we've established this thing is very loud with the sound clips and my description, of course, here, but what else can you expect when checking out the Outlaw Series? Well, again, one of the coolest things, I think, with this exhaust, is that it gives you some options when it comes to configuration, Dual Split Side Exit using these pipes or you can go Dual Split Rear Exit with these pipes, depending on what you're into. Honestly, Flowmaster is one of the only companies I see doing it at this point, and it does make them a little bit more desirable because of that. On the topic of price, guys, you think those extra pipes will add to the price a little bit, and they will, but really not as bad as you might think. In my opinion, the Flowmaster systems, in the grand scale here, are gonna fall in the middle of the road when it does come to price, along with some of the Magnaflow systems and even the Stainless Works stuff to a certain extent. You're looking at right around 800 bucks for the Outlaw Cat-Back here, which again really isn't all that bad when you do factor in that you're getting some options when it comes to configuration and you are getting some pretty solid materials as well. And speaking of materials, the Flowmaster is gonna boast 409 grade stainless steel. Much like that price being middle of the road, the 409 grade stainless is definitely a middle-of-the-road material. You're not getting the 304 on the high side, and you're definitely not getting the aluminized steel on the low side. Instead, 409, a great material overall and very solid and it's something that Flowmaster uses with a lot of their systems. And in fact, it's actually gonna be pretty good at reducing corrosion, if you live in a saltier climate, or maybe a state that sees a lot of salt during the winter months. Going even further with the construction, you're gonna find three-inch mandrel-bent tubing pretty much throughout the entire Outlaw Series System. Again, all 409 grade stainless steel, like we just talked about, the little baby Outlaw Series muffler here, and then finally the twin four-inch tips done up in black. Now, these tips are actually a ceramic coating. They're not painted, which is a lot better for you guys because that means they're not gonna chip, they're not gonna fade, or anything like that over the years. As far as changing out those tips, well, again, something that is very easy to do. You totally don't have to drop the entire exhaust system to do so. You've got the Dual Split Side here, the Dual Split Rear Exit, all of these held on by two clamps. So if and when you did wanna eventually mix it up a little bit, simply remove the clamps, switch out the pipes, and you're good to go. Again, something very quick and very easy to do if you wanted to change them up. As I mentioned at the top of the video, guys, the install's gonna be very straightforward for a majority of owners out there, so let's call it one out of three wrenches on the difficulty meter. A few owners will have to cut, basically regular cab owners with an eight-foot bed or Super Crew owners with a six and a half foot bed. Luckily for you guys, though, Flowmaster lays out very clearly where you need to cut. If you are one of these owners, just make sure you have your Sawzall and a fresh metal blade ready to rock and roll. If not, you're really only looking at a socket set for the rest of the owners out there. So again, we'll call it one out of three wrenches on the difficulty meter, maybe an hour or two in the garage or driveway before you're making some noise. So if you're the type of EcoBoost owner who really wants to be heard and doesn't mind hearing a whole bunch of sound inside the cab of your truck, I think you'll really enjoy the Outlaw Series, and here's why. You're getting some pretty solid materials, thanks to the 409 grade stainless, you're getting a solid build overall, thanks to the Flowmaster quality, obviously that great tone, that loud tone, and then finally the interchangeable exhaust tips, which is a big plus for me. So that's my review of the Flowmaster Outlaw Series for your EcoBoost, which you can find right here at
