Review & Install Video

This MBRP installer series cat back exhausted system with the muffler relocation is for those of you that have a 4-door, 2007 to 2011 JK that are looking for an exhaust system that's going to give you a louder exhaust node, a lower exhaust tone, and also going to relocate that muffler to an area where it's not going to get banged up on the trail quite as much as it otherwise would. This system, as with most other aftermarket exhaust for your JK is going to be a very easy system to install. Definitely a one out of three wrench installation here. Shouldn't take you more than two hours to get installed. Probably less than that, but we'll talk a little bit more about that in just a second. So everything is gonna be nice and tucked up out of the way, again, for those of you that are doing a little bit more rock crawling and off-roading. Now if you're looking for the highest tuck system with the least amount of piping, there are some other options out there that are going to dump right after the muffler in the same position that this is, instead of having this larger over axle pipe that still exits to the back. Those systems are in general going to be a bit louder because they don't have quite as much piping. If you want something louder, if you want something that's a higher tuck, those options are available. But this is still going to be a pretty aggressive system that's gonna be great for those of you that are gonna be going off-road. Our MBRP is able to keep the cost of this system down a little bit because this is going to be built of aluminized steel instead of stainless steel. Now stainless steel's gonna get holed up even better than the aluminized will to rusting conditions. There are a couple of different grades of stainless that are going to be of varying qualities and varying costs. But this is aluminized so it's gonna need to be a little bit more susceptible to rust, but it's also going to be a little less expensive than some of the other options that you might find. You're gonna have all the parts and pieces that you're gonna need to get this installed onto your 4-door JK, including all of the clamps that I don't have on the table here today. That includes your extension pipe, it's, of course, going to include your muffler, your over axle and tailpipe. So it is a very complete system. This is all going to be two and a half inch piping which is the same diameter as your factory piping. All these bends are mandrel bend, which essentially means there's a piece that goes inside the pipe as well as outside the pipe. So when you're getting those bends made, you're not having any tinking of the pipes. So you have a nice flow, you're not having any restrictive points. And overall I do think it's a well-built system. I've seen systems by a lot of those top-end brands, with bigger-name brands, much more expensive systems that don't have as nice of welds on them as this system does. So I do think it's a well put-together system and I think you're gonna get a lot for your money here. Speaking of money again, aluminized, non-stainless also doesn't have a polished tip. It's not a black system that's ceramic coated. None of that. This is really more of a no-frills system. And you are gonna be able to save a bit of money because of that. So for the installation again we're gonna give it a one out of three wenches. Very easy to bolt this up in less than two hours. The first step is, of course, removing all of your factory exhaust components. You'll start by removing the muffler off the back of the jeep. And then the extension pipe that goes from the collector of the headers all the way back to that muffler system. That's really going to be that whole system there. Everything is gonna come off from the collector on the headers all the way back. You're going to be reusing all of your factory hanging points, all of your factory hangers. These are designed to go right onto those. So there's no modification of the Jeep necessary, it will make things nice and easy. And this does come with all of your clamps. So if you have a factory system that's a little bit rusty, go ahead and get it out. Then you Sawzall, cut it up and get it out there any way you can. You're not gonna be reusing any of those clamps but again the hangers you do wanna leave intact. That being said, your system is not overly rusty, hitting it with a good penetrating oil well before you get started with the installation is definitely going to help speed the install along. Once all of that stuff is removed, you'll go ahead and install your new system. You're going to have your extension pipe on your 4-door, followed by your muffler. Then you're going to have this next tailpipe piece here. And finally your over-axle and your exit that's going to go in place. You'll start from the front, working your way to the back leaving all of your clamps loose at first. Then you'll go back through the system again starting at the front and tighten everything down to ensure that everything is lined up exactly how you like it. This system comes in right around $260, which I do think is gonna be a really good deal for what you're getting here. If you step up to one of those bigger brand names, you are going to pay a little more just for the name. And then their systems are also going to be available in high grades of stainless steel, which are going to all add cost. They're going to have polished tips, we're gonna to be getting into systems that are offered in a black ceramic coating. All these things add cost. This is going to be a little bit more of a bare-bones, no-frills system that's still going to work very well, install very easily and get the job done, but save you some money. So if you're looking for a less expensive cat-back system on your JK that's still going to relocate the muffler, give you less stuff to crush when you're off-road, I definitely recommend taking a look at this system from MBRP and you can find it right here at extremeterrain.com

This looks like it bolts up with the muffler clear of the evap box? Eliminating the need to shield the evap box from the heat off the muffler. Is this the case?

    Review from MBRP Installer Series Cat-Back Exhaust w/ Muffler Relocate (12-18 Wrangler JK)

    Sounds like a four-cylinder civic with coffee can exhaust

    pretty straightforward installation. But the sound above 2000 RPMs is very raspy. It sounds like a teenagers import. Pretty expensive also considering it is just a few feet of exhaust and the muffler.

    Was very easy and a great fit. The only thing that was a little tricky was the over axel part. Sounds great and gets better after you drive it.

    System is a bit louder than I had hoped for, but it's a perfect fit in a JK. The main reason I went with MBRP was the muffler relocate. Aint no way I'll be smashing this one!

    Great fit and higher ground clearance. Awesome product!

    This product was extremely easy to install and the pipe was bent perfectly to fit the jk and provide increased ground clearance. Muffler is louder than stock but not overpowering. Great tone!

    Great exhaust at a great price

    It's hard to beat this exhaust for the price. Install was super easy once I removed the stock exhaust. Sounds a bit louder than I expected in the lower gears, but it's a good tone. Not much noticeable drone on the highway. Noticable power increase on the low end, and soon ill know if gas mileage has changed. I'm very happy with this exhaust.

    As loud as you want it or as quiet as you want it.

    Want to start off by thanking Extreme Terrain, fast shipping as usual, excellent customer service, and awesome prices. This exhaust is not difficult to install and the finish product not only sounds great but looks just as good. This exhaust gets rid of the bulky factory exhaust and relocates it under the middle of the Jeep. When I want the exhaust to be loud I get on it hard and everyone looks to see what is that awesome sound, when cruising at 65-70 it doesn't have drone that makes you fall asleep or annoys you. Its perfect. One other thing I wanted to add is the horse power you gain. Its definitely noticeable.

    Bolts up great

    After getting the old exhaust off, bolting up the new one was a piece of cake. Doesn't take long at all. The exhaust was a lot louder than I was expecting, which is great. If you're looking for an exhaust to make your jeep sound a bit more mean, I would recommend this one.
