      Review & Installation 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.

        MBRP Black Cat-Back

        Opening the package I expected the entire exhaust system from the cat converter to tip to be black like the advertisement. Mine came in non-coated steel from the cat through the supplied muffler. From the muffler to the tip was black coated piping so that was a bit disappointing to me especially since the review and install video shows it as fully coated. Other than that, was great, easy install as long as you have a sawz-all handy to cut out those old hangers. Definitely sounds good with a deep note and provides tons more clearance as advertised. Giving 4 out of 5 only for the uncoated parts.

        4 2012 Wrangler - TexasTornado Installation Time: Afternoon

        Sounds great, easy to install

        Tip number one: if you aren't keeping or reusing the stock exhaust, sawzall it out. Tip number two: invest in exhaust hanger removal tool. Sounds great, not whiny like some aftermarket stuff. No backfires. Very throaty growl. Whine at high RPMs decreases at high speeds in higher gears on the highway which is nice for dealing with the drone. The only reasons I'm not giving a higher review is (1) it didn't come with hardware to keep the hangers from falling off (or a bulged bar to prevent this). and (2) a bit worried about the steel over time as it isn't stainless.

        Great system for the price

        This exhaust is a great, lightweight, easy to install replacement for the factory system. The shipping label said it weighed 25lbs. I’m pretty sure the stock muffler alone weighs at least that much. It does have a nice sound to it, but a bit louder that’s I expected, not too bad though. I like it. It really sounds great at 3k rpm, otherwise it’s pretty quite on the highway. The hardest part for me was getting the stock system off. With 88,xxx miles it northeast Ohio weather/roads off roading it was a bit rusty. Took me 4 ½ hours even with a bunch of PB blaster. I ended up just cutting it off with a saws-all. If you have an exhaust hanger removal tool you will save yourself a bunch of time. The hanger in the passenger rear was a real challenge to get off with the adjustable channel locks I was using. Once I cut the pipe I was able to just twist and pull off the muffler. You will need to pry open the slip joints on the factory pipes and hit the clamp with a hammer to get it off. The actual install of the entire new system only took me 20 minutes. Totally worth it though. The black powder coated finish is nice and should really help keep it from rusting out sooner than other systems.

        3 2008 Wrangler - AidanP Installation Time: Afternoon

        After almost a year

        I’ve had this exhaust for almost a year as the title says. The note/sound of this exhaust is great. It actually gets better with time too. Thought it has some problems. The first one may be my fault since I installed it but I don’t think it was. The hooks on the exhaust don’t have anyway to secure them to the hangars like the stock exhaust. The stock exhaust has knobs on the hooks to make sure it doesn’t fall off when it gets bumpy but this one didn’t have the knobs and my exhaust kept unhooking when Offroad so I made my own knobs out of hose clamps and now it’s fine. Problem 2 is one of the exhaust clamps it came with eventually became very very rusty and the pip got loose inside of it and it cause the exhaust to turn and start hitting the track bar and making a horrible squealing noise at the joint. This was easily fixed with a lap joint clamp. The majority of the time of the install was getting the old stuff off. New pipe went in in about 45mins. Tool and hour and a half to get the old one out. If your looking for a mid level exhaust I’d say it’s good. But now that I have experience with it I’d recommend waiting until you could buy a higher quality exhaust that will last you another 8 years like my stock exhaust did until I wacked it on a rock. I can see this exhaust needing to be replaced in the next 2 years.

        Great installation poor exhaust sound

        This was pretty to install but the sound doesn't sound like anything in the video. Make Jeep now sounds like a sick Honda that farts itself while shifting from 1st gear to 2nd. It looks good but man it sounds horrible.

        Great product

        Great Product for a decent price. makes a nice deep sound that is a huge upgrade from stock. very well hidden for better offroad clearance issues. Black finish really makes a difference in looks and making it last longer in all environments. The only thing i would like to see different is a 2/4 door buying option so you dont have to cut it to fit a 2 door.

        2017 jku 2.5 lift on 33x12.5

        Great buy and very simple install. It tucks high into the frame and gives good clearance over the rear axle. I gave it 4/5 for 2 reasons. 1 is I wasn't pleased with the fact they use standard clamps instead of pipe bands that won't crush when tightening. For the price you pay it'd be nice to see that detail covered. 2 the assembly was a little tight but nothing wd40 didn't fix. Overall it sounds great, nice throaty rumble with moderate cruising tone. Still able to hunt while enjoying the sound of an offroad rig.

      Is the whole exhaust coated in black or is it just the tail pipe?

      Would this exhaust require an exhaust spacer kit for a 2015 JKU with a 2.5'' Suspension lift and a 1.25'' body lift running 35's? Thanks.

      • An exhaust spacer is suggested with a 2.5" lift or larger if reusing the stock front driveshaft to prevent damage. If you are not currently running an exhaust spacer, the addition of the MBRP Black Series Cat-Back Exhaust w/ Muffler Relocate would not require one to be added.

      Looking this up on, the muffler is located right next to the plastic carbon vapor canister. Will this cause a problem with heat? Will you need a heat shield for the canister? If so, what would you suggest?

      • There will be no issues installing the MBRP Black Series Cat-Back Exhaust w/ Muffler Relocate on your Wrangler. It will not require a heat shield for install.
