    This Flowmaster Force II Stainless Steel Axle-Back Exhaust is for those of you that have a 2012 and up JK that are looking to getting a little bit more exhaust volume, as well as a lower exhaust note from your exhaust system. Now, there are a lot of options out there. This is the Force II with the dual exit from Flowmaster. There's also a version with a single exit that's gonna be a little bit closer to a factory system. Now all these systems are going to install very easily onto your Jeep. Definitely a one out of three wrench installation. This is definitely something anybody can do in their driveway, and we'll talk more about that in just a second. Now, when it comes to axle-back systems, this one's gonna to be a little bit more expensive than some of the other ones out there, and the reason for that is it's made of a 409 stainless material, with 304 polished tips. Now, the 409 stainless means that while you may get a little bit of surface oxidation on this system, if any of this black powder coat were to come off, you're not going to get full on rust-through like you would with a mild steel system. So, this being a higher grade of stainless steel means that it is going to be a little bit more expensive. And, because you are getting those polished 304 tips, you know you're not going to get any sort of oxidation or discoloration from those tips. So, the build quality and the quality of materials used here is going to drive the cost up a little bit, but again, that all means this system is going to last a good long time Like I said before, any of these systems are going to give you a lower, more throaty exhaust note, and definitely some additional exhaust volume. So, if that's what you're after, this is gonna be a nice choice. Now if you are somebody who does a lot of off-roading, I would probably recommend looking at one of the more high-clearance rock crawler style exhaust systems. This is going to give you not just a factory style exhaust here, you're actually having more piping that sticks out the back that you're gonna to be able to smush off of the rocks. And those high-clearance rock crawler systems are going delete this axle-back completely, give you more of a bullet style muffler, less piping, less stuff to crush on and off-road. So, if you're somebody who stays on the road, runs some mild trails, not as worried about crushing your exhaust, this is great. If you do more hardcore wheeling, you want something that's tucked up a little bit higher, we have that option as well. So, as with most aftermarket axle-backs, this is going to be a two and a half inch mandrel-bent tubing system.The mandrel-bent just means that there is a piece that goes in the inside, as well as the outside of the pipe during the bending process to ensure that none of these pipes are going to collapse as they're bent, which just means that the exhaust is going to be able to flow nice and freely. This is going to be Flowmaster's 80 Series muffler which is going to give you a moderate turn on the outside of the jeep. However, it is going to keep things toned down nicely on the inside of the vehicle. I already went over some of the materials already, this is that 409 stainless with the black powder coat finish designed to hold up really, really well, with those polished 304 tips. There are some systems out there that are completely black, completely polished. If you are more into the looks of this system, again, other options are available, this one does have that black and polished combination, which I personally think is really nice. So, definitely one outta three wrenches on the install of pretty much any axle-back, this one included. All you'll have to do is remove that factory axle-back system by removing one clamp and popping off the two factory hangers. Get that outta the way. Then, you just have to fit this piece of pipe over the factory tailpipe, using the new included clamp, and hang the hangers in the factory location on the factory rubber hangers. Very, very simple installation. Anyone can do this with just a socket set. Now it is a good idea, because we are talking about exhaust systems that like to get rusty, to spray that clamp. And you can also spray those hangers well ahead of time with good penetrating oil. It is gonna make it that much easier to get the old system outta the way. This system from Flowmaster is gonna run you right around $520. And that is going to be much more expensive than the bargain basement systems out there. Now, this is going to be an incredibly well-built system outta some very high-quality materials. It's gonna to give you great sound, it's gonna look good, and it's gonna hold up really well. So, I do think it's worth that slightly higher price tag. However, if you are in the market for a system that has dual outlets, but you're not interested in something that is as well-built, or is made out of the materials that this one is, and you're looking to save some money, you can definitely do that. You can find cheaper systems out there. But, if you want a premium system, this is it. However, it does carry a premium price tag along with it. So, if you're looking for a very well-built dual outlet exhaust system for your JK, I would definitely recommend taking a look at the Force II by Flowmaster, and you can find it right here at

            Best muffler yet

            I love how the muffler sounds, I didn’t even try to do it my self I took it to the muffler shop and within 20 mins I had my flow master done. Sound is amazing I read a lot of reviews saying that it will sound like a civic and this is not the case.

            New Exhaust

            We really enjoy this new exhaust system, its not to loud and over bearing and looks a lot better than factory. It took approx two hours to install, just because it was hard to get the old exhaust off.

            A little louder than expected...

            I have had Flowmaster products on Mustangs for years so I know they tend to be loud. I guess the Mustang has more sound deadening material than the Jeep so I was a bit surprised at the interior cabin noise. Along with the KandN cold air kit, this does slightly improve performance and the dual exhaust looks great on the Wrangler. Sound is good.... but loud. Hardest part of install was removing the stock muffler which I finally had to cut the support arms to remove and then wiggle the muffler off the exhaust pipe as it was rusted. Once it came off, I had the new muffler installed in 5 minutes. Total time was roughly 1 hour.

            Looks awesome

            I had a hard time removing stock muffler so I took it to a shop and I was in and out in less than 30 minuets. I had them weld the Flowmaster on as the clamp I was sent was too big. I preferred the welding anyway. Looks and sounds awesome. Happy with my purchase!

            More than I expected.

            Being around a mechanic all of my life (father) I am a bit of a greaser my self. I was a bit skeptic at first from the reviews mentioning it's more like an import rocket. But combined with K and N intake and JMS pedalmax I am more than happy with the results. The sound is a nice almost V8 loudness. Did not take long at all to install this, I didn't even use a jack. HIGHLY RECOMMEND! And the heads turn when they hear me coming....

            Installing exhaust

            It was a easy install but had trouble with how the tips extended at the bumper , one stuck out further than the other.

            Mad bumble bee!

            From the minute you start the vehicle you will realize this sound should be on a Honda Civic in the fast and furious movies. Why would anyone want an obnoxious rumble in the woods. Sounds great when standing behind the vehicle while idleing. Reminds me of my 1974 Camaro LT. But once inside and you accelerate it sounds like a vehicle that needs a muffler badly.

            Easy to install once you get the old exhaust off, hardest part is getting it off of the rubber hangers, so use plenty of penetrating oil. Sound is great compared to the stock muffler.

            Exhaust note

            The tone has a great rumble at low RPM (under 3 M) Over 3M RPM it gets distorted The Down shift is about the same scenario
