    Review & Install Video

    So the Force II is going to be a simple, full stainless steel, single exit system that should appeal to the 5.0L truck owners out there after that iconic Flowmaster rumble, and want just a little bit more volume over the factory system. But really, don't want the loudest or craziest system out there. The Force II will be on the higher side of the price range, when comparing your single exit, full stainless options, at just north of $600. For most owners out there, there will be no cutting needed. However, depending on your wheelbase, you might have to trim a little bit off this pipe right here. Nevertheless, I'm still going to go a strong one out of three wrenches on the difficulty meter, and we will have some more detail on that later on. Now, one thing I do really enjoy about Flowmaster from a company standpoint is the amount of options they give hot rod owners, truck owners, or whatever, when it comes to their overall muffler selection. They have a ton to choose from. In fact, nearly 20 the last time I checked. The Force II for your 5.0L truck is going to incorporate their 70 Series muffler, which is one of the tamest in the company's rather expansive lineup. Flowmaster actually claims that this muffler is the preferred muffler of choice for truck owners, due to its quiet operation. That is pretty evident with the sound clips. Right, guys? I mean, you heard them. You can ultimately be the judge here. But the Force II is a very tame system. Yes. You're still getting that iconic Flowmaster rumble. But it's not nearly as loud as some of their other offerings for the 5.0L truck, like your Outlaw, or even their American Thunder Series. I do really enjoy that. Because let's face it, guys. Not everybody is after those extremely loud systems for their 5.0L trucks. Daily drivers, family haulers, things like that, you might actually prefer the 70 Series, because this thing will not drive you or the family crazy on those long road trips. So what does this all mean when it comes time to rate the Force II on my tried and true Wake the Neighbors scale? Well, you can probably guess where I'm going with this one. One, essentially being a stock exhaust system, to a five, all the way down the scale here, being an Outlaw Series, for instance, just an absolute screamer. I have the Force II coming in at a strong two out of five on my one to five or one to Wake the Neighbors scale. Again, you're getting just a little bit more volume over that factory system, which some truck owners might be after. If you're not, if you want to rattle the windows in your neighborhood, you might want to look into a different option instead from Flowmaster, like the American Thunder, or even that Outlaw if you're feeling a little brave. But moving away from the sound, let's talk construction and materials, and as we've come to expect from Flowmaster, a very solid build throughout. I've seen how they build these things, guys. I've been around the facilities, and they definitely take pride in their work. Now, their welds could win any beauty content at the end of the day. Well, probably not. But they're a hell of a lot better than mine and they get the job done, and ultimately you are getting a limited lifetime warranty with this particular system. The 70 Series muffler does feature their 16-gauge, 409-grade stainless steel construction. It is loaded with their traditional metal baffling, which is nice because there's no packing material or anything like that in this muffler. So you're not going to have to worry about that sound changing over the years, blowing out, things like that. You're also looking at 409-grade stainless steel for the tubing, all mandrel-bent. Three-inch is your diameter here, leading into and out of the 70 Series muffler, before exiting out the large four-inch tip in the stock location. Now, that tip itself is actually made from 304-grade stainless steel. That is a nice thing to point out, because that's what you're going to be seeing the most of and you shouldn't have to worry about any kind of corrosion on that. But let's switch gears and talk about the installation process here, with Flowmaster's Force II. As I pointed out at the very top of this video, depending on your wheelbase, you might have to trim up this lead pipe here, but it's really not that bad. One cut, a Sawzall, and a fresh metal blade should take care of it rather quickly for you. I do say "some people," because 75% of truck owners out there will not have to cut whatsoever, and make this a simple bolt-on job. Nevertheless, guys, I am going a strong one out of three wrenches on the difficulty meter, and maybe an hour or two from start to finish. As far as your tool list, well, you're looking at a basic socket set to do most of your work with this installation, in addition to that cutting tool if you do need to trim. Just make sure to reference those directions first, then determine if and where you do need to cut. I also always like to recommend a little spray lubricant, not only to help you with the bolts, but also those rubber exhaust hangers, PB Blast, WD-40, whatever you have in the garage. It just makes sliding those hangers in and out a whole lot easier. Now, once it is time to start wrenching, simply loosen up that forwardmost clamp to help you remove the factory exhaust system first. Once the clamp is loosened, go ahead and slide the exhaust off the factory hangers, and then drop it down off the F-150, working its way around the rear axle. Just be careful, guys. This thing is all one piece. It can be a little tricky to maneuver around by yourself. Once that is out of the way, you can get to work hanging the new Flowmaster system in reverse order. Of course, make your cut first, before hanging the system, if you do need to trim up that pipe. Once everything is trimmed, you're ready to rock and roll. Go ahead and hang the system, starting from front to back. But save your final tighten up to the very end. This way, you can just make sure the system is hanging nicely, there's no interference or rubbing anywhere underneath the truck. Then, once you have everything where you like, go ahead and torque down those clamps using your socket set or your impact gun, and your installation is complete. So wrapping this thing up, guys, the Force II is a great way to get that iconic Flowmaster rumble on your V8-powered F-150, but without setting off every alarm in your neighborhood, or driving you and the family crazy on long trips. So that is my review of the Flowmaster Force II, which you can grab right here at americantrucks.com.

    Unmistakable sound. The Force II Cat-Back exhaust system will be sure to give you the powerful sound you are looking for out of your F-150. The muffler is sure to enhance your sound to just the right levels. The low rumble produced by this product is perfect for the person who wants more noise out of their exhaust system, but doesn't want to wake the entire neighborhood.

    Increased power. The mandrel bent tubing of this system makes sure the air will flow through your new system and give you some extra power to your truck. The exit of the system behind the rear tire puts that power exactly where it should be. You'll experience more torque and control than ever before. With the new sound of your system and the added force behind the wheel you'll be sure to impress as you are driving down the roads.

    Finished for strength. The Flowmaster Force II Cat-Back Exhaust is made to last. The materials used in this kit are specifically picked to make sure your system doesn't let up to any forces. The durable stainless steel tubing is strong and corrosion resistant. The muffler and stainless steel tips give you a great look plus a style that will last for miles. The impressive look of this system paired with the durability and quality of the Flowmaster Force will have you feeling like your truck is the most powerful on the roads. The system is also matched with a lifetime limited warranty.

    Everything you need included. All the hardware you need to easily install your new system onto your truck comes right in the box. All you need is some basic hand tools, and the exhaust kit will install right to the factory settings already on your F-150. You won't need to make any modifications to your truck to get this system going, but you may have to cut down the pipe a little depending on the size of your cab and bed.

    can you replace the stainless polished tip for the black tip on other flowmaster exhaust kits?

    Anonymous

    • You will be able to replace the polished tip for the black one from the Outlaw cat-back as the tips will both be 4" in size. With that being said, Flowmaster does not offer the Force II with a black tip.

      Gotta love the sound

      It is worth the price just for the sound. The key to my purchase was sound...NOT too Loud! The stock muffler with the factory resonator just sounded weak...not anymore. As for performance gains, I can't verify with dyno numbers but it does pull harder. If you get this exhaust don't forget a great intake and a programmer to round things out! I highly recommend this exhaust and the sound it makes. If you want really loud then choose another flowmaster system. Will not make the neighbors crazy! Very happy I ordered through American Muscle.
