    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

    I have a 2017 JK 4 door Unlimited Rubicon. Does this kit eliminate the loop pipe or will I have to also get the extra straight pipe to replace that part of the system? I have a 2 1/2” lift so I assume I’ll have to get the spacer kit, too. Thanks

      Sounds great!

      Hardest part of the install was getting the old exhaust off. Easy install and it sounds much meatier than the stock exhaust and I’m happy with the relocation of the muffler as well.

      Great Sound

      I wanted a little more sound out of the jeep but not drony. This was the perfect balance with also adding the loop delete. Pretty easy install, took about an hour on a lift would have take a little more time on the ground.

      Worth Every Dime

      Easy install, but the 2DR owners will need to do some cutting. I used an angle grinder and cut 20.5 inches off like the dealer recommends. Fits like a glove. Adds a great exhaust note and a slight mpg increase ( 2mpg city/hwy) when combined with my CAI and throttle body spacer. No more big ugly muffler on my rear waiting to get crushed. The only difficulty was the removal of the old exhaust. The exhaust hangers need to be lubed up and the old joints need some love, too.

      High Clearance Exhaust

      Was hard to install after I removed the old exhaust. It’s louder than stock when you’re driving, but it’s not bad at all. This exhaust will give you so much more room in the back lower compartment. I’m adding a air tank on my muffler skid plate, just an idea. Hope that you enjoy it as much as I do. My wife didn’t like it as much as I do, but she replaced her muffler too. She also wanted the extra clearance. So it will depend on what you really want from your Jeep.

      perfect fit and sound

      Great exhaust for the money. Couldn't believe how easy it was to install. Perfect fit and look. All the hangers matched up perfect. Nice and tucked up under the body. No concern with clearance when off the road. The sound is Awesome. Did I say the sound is Awesome ? The sound is Awesome. Actually, the best surprise was the increase in performance. Great exhaust. Highly recommended.

      MBRP on 2007 Jeep Wrangler

      Wanted an upgrade, maybe a little better sound than stock and perhaps better gas mileage; accomplished both. Added ground clearance a bonus. Parts fit together well and the clamps were good quality. Sound is definitely louder than stock, but not obnoxious, IMHO. Would recommend.

      Mbrp exhaust

      I love the sound of this exhaust. I had the flowmaster kit and my friend has the magnaflow and this mbrp is louder but the tone is great. I'm very happy happy with it but I only have it four stars because I did have to have one joint welded due to it being a little too big for the pipe.

      MBPR Exhaust

      Most bang for your buck. I enjoy the sound low and gravely. It sounds more about the engine than exhaust. It’s loud without sounding like a rice rocket. I believe this is one of the best exhaust you can buy for an automatic 3.6L engine. I am thoroughly happy with the purchase. If you drive a 2dr though, you will have to cut the exhaust because it comes ready for a 4dr.

      System is nice quality for the price. Install was easy, hardest part was removing old system. A cut off wheel and air chisel made quick work of old clamps and rusted pipes. Jeep has a nice sound, not too loud, cannot hear it over tires at highway speeds.
