    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.

    Is this really gloss black as it says in the description? The picture and video make it look like a stainless finish.

    • This MBRP XP Series Axle-Back Exhaust will be polished stainless. We apologize for the inaccuracy on our site, and will have this updated.

      2018 Jeep Wrangler Unlimited JK Golden Eagle

      The exhaust was easy to install, the hardest part is getting everything straight but I am very picky about that. The exhaust in the back and outside is not to loud but you do get some exhaust drone when it shifts into overdrive at low RPM. I bought some sound deadening mats and have not installed yet. I installed the muffle and installed the sound deadening afterwards. I lined the underside of heat shield and the next section up. I also installed inside in the back and along sides and on the floor in back seat. I still going to do doors and front floor. Now all I hear is a nice exhaust note and not road noise or tires. I think no matter what exhaust you get it will be louder inside so recommend sound mats, I spent less than $100 for the whole jeep. The exhaust is deep and raspy and pretty quit when driving. I think for the price this being $100-$200 cheaper then the other axle back systems you get your money worth. Magna flow is a nice system but not worth the extra money plus this system is much more adjustable because it comes in pieces with clamps "I Like That". If you have ever heard a V6 Challenger is sounds a lot like that, pretty good for V6 IMO. A head turner now. I find it hard to give anything 5 stars but this system is nice!

      A good looking exhaust

      Easy to install, and to adjust the tips.the hard part of the job was taking the old exhaust off. I thought it would be louder then what it is. The noise level is just a little higher than stock. Hopefully it will get louder after it breaks in. All in all looks well built,look good on my 2012 jku.

      Good quality sound

      Just installed thid exhaust on my 2010 JK last night. The installation was fairly simple. I removed old exhaust which wasn't that hard. I used the old clamp along with the new one where it attached to tail pipe. Found that gave a tighter install. You will need to remove the center spacer to get a tighter clamp down on the pipe. The hardest part was aligning the tail pipes. This takes some time to measure and get just right. I suggest using a hole under the frame to bend the hanger support some for the right side. Other than that it was a perfect fit. Looks great! It sounds good, nice throaty sound. Does have some drone in final gear. This may get better as it burns in. But it's not bad.

      It looks good, but performs bad!

      If you are all about the looks, go for it. However, your ears will not like it. If you only drive your Jeep off-road, also go for it, but if you drive it to work, do not. The problem with this system is not the sound itself, as they sound good, but the vibrations they make as you drive, specially around 2000 to 3000 RPM, as that is the range a driver would be at driving on a normal road most of the time. The longer the trip was the more I found myself having difficulties staying in my Jeep. You feel the vibrations from the exhuast drilling into your ears and head like a screw. At the end I found myself replacing back the old one. This website 5/5 The exhaust 2/5

      Nice exhaust for the money. Sounds good, looks great and didnt have to break the bank. Install was easy after a bit of a fight removing the factory exhaust. Extremely satisfied.
