Jake: Jake here for ExtremeTerrain. And today, I'm taking a look at the Flowmaster FlowFX Axle-Back Exhaust with Black Tips, fitting 2021 and newer Broncos, excluding the Raptor. Now, the Bronco's stock exhaust doesn't sound like much, so you can bring some serious personality into the mix with this FlowFX axle-back. This brings Flowmaster's tried and true approach to exhaust systems to the Bronco, and gives it a much-needed injection of sound, without having to spend a whole lot of money. It's a great middle-of-the-road type of setup that gives you more volume without going way over the top. For that reason, this one gets a very strong three out of five on our loudness meter. Passers-by are definitely gonna know something's up, but you're much less likely to get your neighbors all riled up.Whatever body style or engine size you've got in your Bronco, I think we can all agree that any of them could stand to make a bit more noise. And if more volume is what you want, then the FlowFX axle-back we've got here today delivers. And as you heard from the clips at the beginning of the video, this is going to inject your Bronco with a much better sound than stock. You get a deeper and more aggressive tone, but one that still isn't over the top, whether you've got the four-cylinder or the six.It's a bit more aggressive than Flowmaster's own American Thunder series, but it doesn't push the envelope too far, especially since this is just an axle-back. So it's gonna keep the majority of your stock system intact. In place, you get one of the FlowFX bullet-style mufflers here, which is definitely gonna have less baffling inside than your stock one, hence that more aggressive exhaust note. But as you can hear, you still get some nice resonance to it. It's not too super loud. This is also gonna breathe better than your stock exhaust. And since an engine is essentially just an air pump, more airflow is always better. And better flow means less back pressure, which is also important for turbocharged engines.All of that also means that you are gonna get some more sound inside of the cabin. But much like the outside, this isn't gonna go totally over the top. You're still gonna be able to enjoy some tunes or hold a conversation, making it suitable for something you do drive daily. Carving the whole thing off, of course, are a pair of black ceramic-coated 4-inch tips. It's gonna pair that aggressive sound with a more aggressive look too.Now, this system does keep the tips pretty tight to the body and bumper of the truck too, as you can see in the clips here. So, if you are doing some off-roading, this isn't gonna ruin your departure angle or anything like that, so you don't have to worry about dragging it along if you're hitting any obstacles. So, it's gonna look cool and it's not gonna have any negative effect on your off-road performance. And it's gonna sound better too.This system is made from 409-grade 16-gauge stainless steel. The piping is 3 inches in diameter all the way out to the tips, which, again, are 4 inches. And that means that you're gonna get excellent exhaust flow out of it. Now, that 409-grade stainless that we have here means that you're gonna get some solid protection against rust and corrosion as well. So, if you are using your Bronco in any kind of inclement weather or going off-roading, that's important.Now, of course, this isn't gonna provide the same level of resistance as T304 stainless, but it also doesn't have the price of T304 either. Speaking of which, this system is gonna run you about $500, and that makes it one of the most affordable exhausts in the entire segment, even as compared just to other axle-backs. It's a lot of good sound for not a lot of money. So, if you like what you heard in those sound clips and you like the look of the tips, I think you're gonna be pretty pleased with your purchase here.Installation is gonna get a one out of three on our difficulty meter, and it should only take you about an hour to get this done. Now, since this is just an axel-back, it does end up being a bit less complicated than a full cat-back system. So, accordingly, it's gonna take you less time and be a little less difficult. And this is a pretty simple process. You get everything you need included in the kit, including new hangers and isolators for you. And everything just bolts on so you don't have to make any modifications to your rig.And to show you exactly what's involved, let's go ahead and jump on over to the install bay.Man: For this install, you will need an impact, ratchets, extension, 10, 13, 14, 15, and 18-millimeter sockets, 10 and 14-millimeter wrenches, a hanger removal tool, and some penetrating lubricant. What's up, guys? Today, we're gonna be installing a new exhaust on our Bronco. So, let's get started. So, our first step is gonna be to loosen up our clamp to our muffler inlet pipe. And to do that, we're gonna use our 15-millimeter socket on our impact.Next, we can go ahead and remove our hangers from our isolators using our hanger removal tool. And it's always a good idea to spray a little penetrating lubricant into where your hangers are just to make sure they slide out easily, just like so. Go ahead and get that one loose, and then we'll move over to our other one. Now, you do want to grab ahold of your muffler because it'll be ready to swing after this. Go ahead and pop this other one all the way out. Go ahead and get this other one all the way out. And we can go ahead and wiggle our muffler out, and set our factory system aside.So, for this particular system, we're gonna be replacing this rear hanger here from the factory with the supplied aftermarket one. So we're gonna need to remove it. And these do have captured welded nuts on the bracket, so we will have to unbolt our bumper just to access the bolts through the back of the frame here. So, we're not gonna actually take it off all the way, we're just gonna unbolt it to give us some room to access those. So, first, we're gonna remove our bottom two 18-millimeter bolts on each side using our 18-millimeter socket on our impact. And then we'll go ahead and remove the other two on the other side. And your tow hook is held in by a little clip, but you can just pull it right out.So, next, we can come to the backside of our bumper here, next to our frame rail, and remove this upper inside 13-millimeter bolt using our 13-millimeter socket on our impact.And then we'll go ahead and remove the same bolt on the other side. Okay. So, now, that we have our bumper unbolted, we've got it supported on pole jacks, but if you have a buddy or jack stands, you can do the same thing at home. So, we've just gone ahead and pulled the bumper back, and there are these two access holes to access the 10-millimeter bolts that are holding our factory isolator hanger in. So, we'll go ahead and use our 10-millimeter socket on our ratchet and just get up in there and remove these two bolts.Now, there are holes on the bottom of your frame, so don't worry so much about dropping the bolts. If you do have easy access to them, you can go ahead and get the first one out and you can remove the second one.Now, the second one, you don't really have to pull out, but if it falls out, that's okay. So, now we're gonna get ready to install our new supplied hangers, and for that, we're gonna make sure our passenger side hanger is curved around and facing back towards the center of the vehicle, like so. And then we're gonna take our factory hardware, slide it through our second bolt hole in, go ahead and attach our supplied lock nut loosely for now. And then our other bolt is gonna go in one, all the way closest to your hanger bend point. We'll go ahead and install that lock nut as well. Then we can go ahead and set this loosely in place. So, now we're gonna go ahead and tighten down our lock nuts just a little bit more before we install them.So, I'm gonna use my 13-millimeter socket on my impact and a 10-millimeter wrench. You can go ahead and run that down a little bit. Do the same thing for the other side. Now we can go ahead and slide our bracket bolts back through our slots here, move those into position. Now you can sneak a 10-millimeter wrench up in one of these access holes here. Then we'll go ahead and use our 13-millimeter socket, tightening this down, get that snug. We'll do the same thing for this one. Okay. Now we'll go ahead and do the same thing for the other side. So, now we're gonna use supplied hardware and a 14-millimeter shallow socket, as well as a small extension, fish the mounting bolts for this side up through into our holes. So, once we have our first one in, we'll get our bracket in place.Again, we're going to go second, pull here, closest to the bend in your hanger. And then we'll use our supplied flat washer, lock washer, and nut. We'll get this one loosely in place for now, then we can go ahead and get our other one installed. And the same thing, flat washer, lock washer, and nut, put that hand-tight. And then we'll go ahead and grab our 14-millimeter wrench, as well as our 14-millimeter socket, and extension on our ratchet. Let's go ahead and tighten these down. Now we can go ahead and reattach our bumper, and we'll start by hand-tightening our 13-millimeter bolts here on the outside of our bracket to our frame. We'll get this one hand-tight, as well as the one on the other side.Now we can go ahead and thread in our lower 18-millimeter mounting bolts. Then we'll do the same thing on the other side, as well as attach our tow hook. Now we can put our push clip back in the middle section of our tow hook, push that back up into place to hold it, then go ahead and thread in our two 18-millimeter bolts on this side. Now we can go ahead and tighten our outer bolt down using our 13-millimeter socket on our impact and go ahead and do the same thing for the other side. Now we can go ahead and tighten down our bottom bolts using our 18-millimeter socket and our impact. And you can repeat this on the other side. So, this particular system we're installing does not reuse this factory hanger isolator point, so you do have the option of removing it with two 10-millimeter bolts right here.For demonstration purposes, we are actually gonna leave it in place, but if you wish to take it off at home, you can without affecting anything. All right. So, now we're ready to install our new system. And we're gonna start by installing our new hanger isolators onto our supplied hanger rods, and we can go ahead, get our new system up into place. We'll start by lining up our inlet tube to our muffler. We can go ahead and get our hanger isolators in place. Now, for this side here, it may even be beneficial to put your isolator down onto your exhaust part as opposed to the hanger on the body. It's a little less long. With a little persuasion here, you can get that lined up and slide that into place.So, now, before we tighten our clamp down, we can go ahead and make any adjustments we need to make sure our tips are lined up and symmetrical and nice and even. One thing to note here for the orientation of your hanger rod brackets, you wanna make sure they are facing the top of your plate as opposed to the bottom or your exhaust will hang too low. So, you just want to keep that in mind. We'll go ahead and line up our tips here, get them pretty straight. Then we can go ahead and tighten our clamp down using our 15-millimeter socket on our impact.All righty, guys, that about wraps up our review and install of our Flowmaster FlowFX Axle-Back Exhaust with Black Tips for your '21 to current Ford Bronco, excluding the Raptor.
