    Review & Install Video

    I'm Ryan from and this is my review and installation of the MBRP Axle-Back Dual Rear Exit Exhaust, fitting all 2007 and up JKs. Today we're gonna talk through the installation of this exhaust, as well as how it sounds, and some of the features of the construction. A lot of you will look to swap out the factory exhaust on your Jeep for an aftermarket axle-back because you're looking for more volume and a lower exhaust note. And this system will definitely give you that, but because this is a dual exit, you'll also get more of a unique look on the back of your Jeep. Now, nothing is gonna make your V6 sound like a V8, but if a little bit more volume and a lower tone note are what you're after, an axle-back like this one will definitely do the trick. Now, this axle-back from MBRP is a little bit more expensive than a lot of the other ones on the market, and part of the reason for that is this is a stainless steel system. This system's going to hold up a lot better than an aluminized system or a mild seal system would, so you are going to have to pay a little bit more for it. As I mentioned, this is a stainless steel system. Everything you see here is mandrel-bent, 409 stainless tubing, with, of course, an MBRP muffler right in the center. The tips, however, are a 304 stainless so they're going to stay looking good for a really long time. The 409 stainless that all this tubing is made out of will eventually get a little bit of surface rust on it, especially if you live up in a salty area in the winter like we do. This isn't going to rust through, but you can expect to see a little bit of surface rust on that 304. Anytime you let the Jeep breathe in or out more easily, you should theoretically see a little bit of additional power, or at least a little bit better throttle response. Now, what you're swapping out here is just the axle-back, so you still have the cats, the resonator if you have a newer Jeep, all the way back through the piping, that is still going to be restrictive. So I wouldn't expect a ton of performance out of this axle-back. What you can expect is what we've talked about before, of having some additional volume and a lower exhaust note. Now, one thing that is a little bit interesting about this system as opposed to a lot of the other ones on the market, is this actually comes in a few different pieces. These elbows here, the inlet pipe, both tips, and the muffler are all separate pieces that are designed to be clamped together during the installation. Some of the other axle-backs we have on the site will have everything welded together, except for the tips. So it's just a little bit of a different design. I don't know that this is necessarily better or worse, as long as you get those clamps nice and tight, you're not going to have any leaks, so it shouldn't be a problem. I would give installing any one of these axle-backs on a JK a very simple one out of three wrenches. The most difficult thing you're going to have to deal with when swapping out the factory exhaust on your Jeep is rust. There is one clamp with one nut that you'll have to break loose, and exhausts can get very rusty, so I definitely recommend spraying that as well as the factory rubber hangers with a good penetrating lubricant well before you get started with this installation. Then it's just a matter of using a wrench to break loose that one nut that's holding the clamp on your factory axle-back, and use a pry bar to pop loose those factory rubber hangers. Once the factory exhaust is out of the way, you can go ahead and start installing this one. Now, because this install is in a couple of different pieces, I would fit the inlet pipe on the factory hanger and this outlet pipe on the factory hanger, then you can go ahead and hang the muffler in between the two. And, finally, the second outlet pipe. As you're assembling things, you'll wanna make sure that you put all the clamps in place, and don't tighten anything totally down until you have the tips in place, and you make sure they're positioned exactly where you want them, and even. After that, you can tighten everything down and you're done. You won't need any specialty tools for this job, just a socket set and that penetrating oil, and the whole installation shouldn't take you more than an hour. Now, because this system is made out of a higher quality 304 stainless, you would expect it to be a little bit more expensive than some of the other axle-backs on the market, and that is the case. This is going to be one of the more expensive axle-backs that you can get for your JK. However, if you're looking for something that's going to hold up really well over time, nothing beats a high-quality stainless exhaust system. So, if you're looking for a lower exhaust note and a little bit more exhaust volume out of your Jeep, as well as a unique look from the back by having the dual outlets versus the factory system, I think this is a really nice option. And, if you have the budget for a system made out of the high-quality materials that this one is, you're gonna get something that's gonna last a really long time. So that's my review of the MBRP Axle-Back Dual Rear Exit Exhaust, fitting all 2007 and up JKs, that you can find right here at

    Let your Wrangler Growl. Compared to a single exhaust, a double exhaust design allows more flue gas to exit from the engine so it can run more efficiently, while affording it an unleashed exhaust tone that gives it a little bit more mean factor.

    Built to Last. Now, you have an option to either have this product in either T-409 Stainless Steel or high quality aluminized metal construction, which are both resistant to corrosion. In addition, this exhaust system also comes with a polished T304 Stainless Steel tip for added aesthetic appeal.

    Bolt-on Installation. The axle-back dual rear exhaust system features a bolt-on installation that can be done right in your driveway. The kit comes with two (2) Tail Pipes, an inlet pipe, muffler, four (4) clamps, and T304 polished stainless steel exhaust tips.

    Application. This MBRP Axle-Back Dual Rear Exit Exhaust System is specifically made for the 2007-2018 Jeep Wrangler JK.

      Great fit great sound

      Easy install about 1hr adjusting for nice level fit was the trick, nicer than those fixed tail pipes like some others this axle back lets you fine tune and tuck for a clean fit ,used a finger from bumper and great look. Sound is not to loud but a nice throaty sound , not annoying and radio still sounds great , Great finish like all MBRP products worth the money

      Excellent Exhaust for the $$$

      Feel like I got a great deal on this. Price was right, arrived quickly and felt like a quality piece. Install was super easy, maybe 30 min. If you are looking for a deeper, less ricey note to your exhaust this one is for you. Put it on my daily driver and I barely know its there, except when I put my foot in it. No drone on expressways. Really happy with this purchase.

      Pretty Decent

      This is a pretty decent axle-back... The quality, fit and finish are good and other than getting the stock muffler out, this was an easy install in my driveway...on a 40 degree day even. Took about an hour. The sound isn't at all annoying. It just gives a nice growl under acceleration. At idle it is quiet, yet more audible than stock and overall it is not loud enough where you're going to be pulled over by the police. The black finish is great and I think if you are in a winter climate with salt, this should be what you do as it protects the metal. Looks really nice. All I really wanted was something I could hear, and I am pretty happy with it.

      MBRP Exhaust

      When I read others review, they said they couldn't believe how loud it was. I didn't think it sounded that loud. It has a deeper tone for sure! My wife says it sounds kind of Fast N Furious like. I like to think it sounds tougher than that but I have to remember that it isn't a V8. Good system for the money compared to others of the same type.
