Review & Install Video
Ryan: This MBRP Installer Series Cat-Back Exhaust System is for those of you that have either a two-door or a four-door 2018 and up JL with the 3.6 liter engine that are looking for an exhaust system that's going to change the exhaust volume as well as the exhaust tone. This it going to be a relatively easy two out of three wrench installation if you have a two-door JL. You are going to have to cut one of these pipes but because you're not actually cutting or drilling into the Jeep, we're gonna stick with two out of three wrenches instead of three and we are gonna show you how to install this in just a second. So, most of you are gonna look to swap out your exhaust system for one of a number of different reasons. Of course, the first and foremost is going to be exhaust volume and exhaust tone, both of which you're gonna get from this system. Another would be if your exhaust system is rusted out, you banged it up on the rocks, it is just twisted, it needs to be replaced. Of course, with a brand new Jeep like the JL, rust probably isn't the issue but you still might need a replacement and instead of going with a factory one, an aftermarket is gonna be a pretty good choice for you. And finally, a lot of you are going to wanna change up your exhaust system so we have one that has less piping that can get mangled on the trail. So this system is going to be a little bit shorter.
It's not going to have that large muffler in the back area of the Jeep. So, if you're worried about banging stuff up on the trail, this is going to tuck things a little bit for you. However, this is not a full-on off-road system that is going to be, for instance, a dump in front of the axle. This is still going to exit out the rear of the Jeep. But what this system is going to do for you is not only eliminate the factory muffler but also the factory resonator, replacing both of those with just this bullet style muffler and then, of course, they're going to give you all the piping to make this work. So, from the collector, the piping into the muffler. From the muffler, the piping out the back of the Jeep. So, if you are looking for a system that is going to give you this sound and that is this style, this one's going to be a little bit less expensive than some of the other choices out there, and part of that reason is that you do have to cut if you have a two-door JL. The other part is the fact that this is aluminized steel. So a lot of exhaust systems are going to be either aluminized steel, 409 stainless or 304 stainless. The different levels of stainless are different amounts of rust resistance. This being aluminized is going to help it to resist rust but if you're somebody who's in the Rust Belt like we are, this system still may end up rusting out on you over a long period of time where a very high grade of stainless simply is not going to do that. So, if you're looking for even more longevity, maybe take a look at the more expensive systems that are made of that 304 stainless.
If you wanna save a couple of dollars and you're not as worried about rotting out, this aluminized system here from MBRP is going to be more than good enough for you. Speaking of saving you a few dollars, this system is going to come in at right around that $240 mark. I think that is very, very fair for what you're getting here. As I said, you're getting the muffler. You're getting all the piping. You have all the hangers, all the clamps, everything you need to make this work for a very fair price and this is going to drastically change up the sound of the Jeep, in my opinion, making it sound a lot better than from the factory. As we said before, we're sticking with two out of three wrenches for this installation. Let's show you how to do it.
Speaker 1: Tools used for this install are 13-millimeter socket, 15-millimeter socket, power ratchet, 3/8 impact gun, pry bar. All right, we're gonna start off at the clamp right before the muffler. I have a 13-millimeter socket on my ratchet. I'm gonna break it loose first and then switch over to a power ratchet. Next thing I'm gonna do is spray the rubber exhaust hangers with some WD-40. That's gonna help us slide our hangers out. We have one at the resonator and two at the muffler. Next thing we're gonna do is start to remove exhaust hangers. I have a hanger removal tool here. It's gonna help me get this mount out of the rubber. If you guys don't have one of these, you can use a pry bar. And we can move back to the muffler now. All right. So there is not enough room to slide the entire cat-back out in one piece. So, we're gonna remove the muffler. I have a 15-millimeter socket on my impact gun. Once we have the muffler out, we should be able to slide the rest of the cat-back out nice and easy. Before we begin our installation, we need to take the factory clamp off here and we're gonna do that by prying up on this tab right here and we'll be able to slide this right on out. Step one of our install here is going to be to slide the stock clamp over the end of the front pipe here and then we're gonna take this and slide it right on to our stock exhaust.
We're not gonna tighten this up all the way. We're just gonna snug it down so we have room for movement. All right. Next thing we're gonna do is install our muffler. Let's not forget to slide a clamp over the end of our pipe here. Take a muffler and slide it right on into place and we're gonna leave this clamp loose as well until the very end. Next thing we're gonna do is cut our over axle pipe. Depending on whether you have a two-door model or a four-door model is going to depend on where you need to cut your pipe. We have a two-door model so we're gonna cut off the end here. Measure back 21½ inches and make our cut. All right. We can now install our over axle pipe that we just shortened up. I'm gonna spray our rubber isolator with some WD-40 here and don't forget to put a clamp into your muffler here. All right. We're now ready to install our tailpipe, gonna spray our our hanger and we'll slide a clamp over the end of our axle pipe. All right. I'm gonna start to tighten up my clamps now. All right, guys. That's gonna wrap up our review and install. Be sure to check out more at extremeterrain.com.
