    Review & Install Video

    I'm Ryan from extremeterrain.com and this is my review and installation of the MBRP Exhaust System with Muffler Relocate fitting all 2007 and up JKs. There are a few different versions of this system available. One for those of you with a 3.8 and another for those of you with a 3.6-liter engine. There is a different version for those of you with a two-door and the four-door, although if you do have the two-door, you are still going to have to do some trimming of one of the pipes. And finally, the system is available in an aluminized finish and also in aluminized metal that's covered in a high temperature black coating like this system that you see here. Today we're going to talk through the installation of this exhaust system which I give a very simple one out of three wrenches. This will bolt directly in place of that factory system and have a drastic impact on not only the sound and attitude of your Jeep but also of the looks. We're also going to talk about that sound, the lower exhaust note and additional exhaust volume that you can expect from the system. And finally, a few of the other features and the construction. These systems are known as high clearance systems or muffler relocate systems like this one is. And what they essentially do is take that big bulky muffler that's sitting right in the back of the Jeep just asking to be crushed on a rock or a stump and relocate it up into the area where those newer Wranglers have a resonator. So if you have a newer Wrangler, this is going to delete the resonator and put a much smaller bullet style muffler in its place and completely delete that rear muffler. What that gives you is a lot less piping and a lot less stuff to be crushed and damaged on the trail, all while producing that lower and louder exhaust note that we talked about. The system is made of aluminized steel which in the world of exhausts is one of the lower grades of material that you can get. However, this does come with a three-year rust through warranty and the black system is going to hold up better than the uncoated system because it has one more barrier of protection. These systems are made of 16 gauge two-and-a-half-inch mandrill bent pipe and what that means is there's a piece that goes on the inside and the outside of the pipe so that during the bending process, the pipe doesn't collapse causing a choking point. This allows the exhaust to be very, very free flowing. As I said before, the black system and the uncoated system are both made of aluminized steel which will hold up better to the elements than a mild steel but not quite as good as a 409 or 304 stainless system would. The coated system is going to be a little bit more expensive but again, it is going to hold up a little bit better and it will certainly give you some additional attitude. Something that makes this system a little bit different from some of the others is that it doesn't have an actual tip that you put over the top of the tail pipe. This is a baloney cut tailpipe that gives you an integrated tip look which I like. It's minimalist and especially in the black, I think it looks pretty good. Like I said before, the installation for the system is going to be a very simple one out of three wrenches. The only difficult part about this is going to be rust. Those of you who have worked on exhaust systems before know that they can get rusty and that can add some time to the install. So I would recommend spraying all of the bolts, clamps and even the hangers with a good penetrating oil well before you get started. It's going to pay dividends during the installation. After that, it's just a matter of removing your factory system which you'll do by removing all of the factory clams and hangers starting at the rear and working your way forward. After that, you can install your new system which you'll do starting at the front with an extension pipe. Then the muffler, then this piece here which is actually the piece that you're going to be trimming if you have a two-door. You will have to cut 20-and-a-half inches off of this pipe although I would recommend doing a few test fits. Not just going by the 20-and-a-half that's in the instructions. Test with the pipe and cut it exactly how you need it. And then finally, installing the rest of the over axle pipe with that integrated tip. Again, these are all going to fit right into your factory hangars making this system a very easy install. One thing that's a little bit different about this system and some of the others, like I said before, there are two different versions. One for those of you with a 3.8-liter and one for those of you with a newer 3.6-liter engine and the only difference is really where these front hangars are located. A lot of other manufacturers would just weld both hangers in place and sell the same system for both engines. MBRP doesn't do that. They give you the one hangar that's going to work for your year range but that does mean you need to make sure you're getting the exact system for your year of JK. So as far as tools, you won't need any specialty ones. A good penetrating oil and some hand tools to get this installed and as far as time goes, I would give yourself a little over an hour to get this installed. Especially if you have some rust on your Jeep. This system seems to be priced right in the middle of the road as far as muffler relocation or high clearance exhaust systems go. These systems are a little bit different than just an axle back that just replaces your muffler so, of course, they are a little bit more expensive than those. However, this is going to save you some money out of a 304 or a 409-stainless system. Being aluminized, again, it is considered to be a slightly lower grade material but this does have a three-year rust through warranty so it is going to hold up for a while. If you're looking to save a few dollars on your system and still get that lower exhaust note and that additional exhaust volume as well as the additional clearance that this provides, I think this is a good option. If you are willing to spend a little bit more and you want something that's going to hold up really well even longer, then maybe look at one of the stainless systems that are available. So whether you're looking to swap out your cat-back system on your Jeep because you want a lower exhaust note and some more exhaust volume or you're looking at this system because it provides some additional clearance for an off-road rig, this is going to be a really nice option that will give you the best of both sound and clearance. So that's my review of the MBRP Exhaust System with Muffler Relocate fitting all 2007 and up JKs that you can find right here at extremeterrain.com.

    Construction. MBRP's installer series cat-back system is constructed out of 16 gauge, aluminized steel. The aluminized finish resists corrosion and acts well as a heat exchanger. This system is 2.5 inches in diameter and features Mandrel bends for optimal air flow. The welded hangars provide a strong and secure fit. The system comes with saddle clamps to assist installation.

    MBRP designed this system for off-roaders. The muffler is relocated to behind the catalytic converter to increase your Jeep's ground clearance, and so you won't have to worry about damaging your new exhaust while navigating the trails.

    Application. MBRP backs this system with a three year warranty. This system fits 2012-2018 JK Wranglers, both 2-door and 4-door models.

        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

        • This cat back system will connect after the Y pipe and will not effect the down pipes or require cutting out the exhaust loop.

            Deep sound and simple install

            Worst part was getting the stock muffler off. We had to use an angle grinder to get some off. Additionally you have to cut one of the pipes to make it fit on a 2DR. Once that is off it is basically plug and play. The sound isn't too loud but it is throaty and definitely gets people looking at your ride!

            Great product, keeps everything up tight to the frame. As everyone else said, hardest part is getting the old system out. I grew up around V8s with dual exhaust, obviously you cant get the same sound out of a V6, but it does have a throaty sound to it, i wasnt sure i liked it at first but its grown on me a lot.

            Great bang for your buck, I love the way it tucks up out of harm's way. The sound is definitely louder than stock but not obnoxious. My son and I took it for a test drive and we're able to carry on a conversation easily. Parts were very well made, the quality seems very high, I would recommend this system for a great replacement/upgrade.

            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.

            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.

            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.

            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.
