      Review & Installation Video

      This MBRP Black Series cat-back exhaust is for those of you that have a 2012 and up JK, and are looking to get a lower and louder exhaust tone, while changing up the attitude of your Jeep with this black single outlet, all while saving some money. This is going to be a little bit less expensive of a system than some of the others out there on the market. Now, this will fit your 2012 and up JK, whether you have a two-door or a four-door. If you do have a two-door, you're going to have to do a little bit of cutting to get this system to fit, but either way, still a pretty easy install, and we'll talk more about that in just a second.This system is made of aluminized steel covered in this high-temp black coating, which is one of the ways that MBRP is able to keep the cost of this system down a little bit. A stainless system is going to be significantly more expensive than aluminized steel is, but the black coating on this system is still going to help it to resist any rust or corrosion that you might otherwise get if you just had a bare aluminized system. This system does have a 304 stainless tip that's also black powder coated, again, giving you that little bit of additional attitude.Now, this system here is going to keep your muffler in the same location as the factory muffler. It's just, of course, a smaller muffler, but this will completely delete your factory resonator, which is part of the reason that you're going to get that lower and louder exhaust note. There is, also, an MBRP system similar to this one that will relocate this same style muffler up to where that factory resonator sits, so you're going to have a little bit less stuff to get banged up on the rocks. If you spend time on a trail, that might be a better system to take a look at.This is going to be a one-out-of-three-wrench installation that shouldn't take you more than an hour to complete. Although, if you have worked on exhaust systems before, you know that they are rust magnets. It's a great idea to spray all of the clamps, nuts, bolts, and hangers well ahead of time with a good penetrating oil. Do it multiple times if you can. It's definitely going to speed the install along.Now, the first step in this installation is really working from the back to the front, removing all of the components up to the catalytic converter collectors. That'll include, of course, removing your muffler, your over-axle pipe, your factory resonator. Get all that stuff out of the way by first removing the clamps, and then pulling, tugging, prying, whatever you need to do to get that system out of the way.Once that is completely out of the way, if you're installing this on a two-door JK, you are going to have to cut this extension pipe down. Just follow the instructions. You're going to cut around 20 and a half inches off of the system. You can do that with a cut-off wheel, with a hacksaw, with a sawzall, whatever you choose to use to make that cut.After you've made that cut, again, if you have a two-door, or if you have a four-door, just right out of the box, you'll attach this extension pipe to the factory hanger and to the catalytic converter collector pipe with the clamp that is included. After that, you will attach the over-axle pipe to that. Finally, attach the muffler, the tailpipe, and the tip. Now, leave all of those clamps loose for the time being. That way, you can level and get everything set exactly where you want it, then work, again, from the front to the back, tightening all of your clamps.This system will run you right around $400, which is one of the less expensive cat-backs that we have on the site. And the reason that this is a little bit of a lower cost is the fact that this uses that aluminized steel versus a stainless steel. Now, if you live in the rust belt, if you want a system that's going to last a really long time, you probably want to look at one of the stainless systems. However, if you're on a bit more of a budget, you're not as worried about rust, you don't live in an area where there is rust, then going with an aluminized system and saving a little bit of money might be just fine for you. And, even though this is an aluminized system, it is covered from tip to tip with a high-temp black coating that's definitely going to help cut down on the rust. So, all in all, I think this is a pretty good deal.So, if you're looking for a black single outlet that'll save you a little bit of money, I'd definitely recommend looking at this MBRP Black Series cat-back exhaust that you can find right here at

        MBRP cat back exhaust

        Very easy to install but doesn’t quite back fire like in the video. I’ve checked for leaks and haven’t found any. Over all 9/10 looks and sounds great!

        A bit disappointed!

        I received this exhaust today, when I opened the box, 2 of the 5 parts that completes the exhaust are silver and not black like it shows on the website pics. I will now have to spray paint them with heat resistance those silver parts. That defeats the purpose of saving time to install other Jeeps parts. I won’t buy this item again for my next JK project.

        Very easy installation hardest part of the job is getting the old exhaust off. After the old exhaust was off took me about 45 minutes. Great sound not over bearing but still gives you a great low rumble. For the price would def recommend

        Easier Than I Thought

        I really didn't want to deal with this, but since I was temporarily laid off I felt I had no excuses. Follow the directions and it is quite easy. I did not remove the skid plate brace as advised in the directions, as I was able to gitter done without doing so, however, it would have only taken another minute or so to remove it. Also, the Jeep has a lift kit and large tires, so no jacks/stands were needed. In total, it took me about two hours, but I wasn't trying to get it done quickly. Saved over $360 based on the estimate I got to have it replaced. Nice growly sound to the muffler, too.

        Very well made!

        The installation was easy and well explained, although I am a ASE technician, I tried to look at the instructions as if I knew nothing. The sound is a little bit too "tuner car" than I would prefer, but it is a single out on a V-6, so it's what I would expect. Hopefully, the sound will mellow out as the exhaust burns in. Overall, I'm very pleased. The quality is very very good for the price point the look is great, and the installation was nice and easy!!

      Noise? Describe or can you compare anything? I have a soft top. Let me say this-_When I bought it, i didn't know the tires hummed. Next day, a new set. This exhaust system, does it sound deep or just loud? Like one of those rice jets annoying you as they pass you? Wouldn't mind getting more power, torque. Any ideas for me and the misses would be appreciated.

      • The MBRP Cat Back Exhaust - Black (07-11 Wrangler JK 4 Door) features a very throaty and loud (yet fairly conservative compared to others) sound. This system may not be preferred when running a soft top.
