      Video Review & Installation

      Hey, guys. So, today we're checking out the RedRock 4x4 Axle-Back Exhaust system with polished tips, fitting all 2018 and newer JL Wranglers with the 3.6-liter V6. So, if you're in search of an upgrade for your factory exhaust system that's going to upgrade the sound, the performance, as well as the styling of your JL, then this is going to be a great choice to take a look into. So, this exhaust system is going to free up a lot of restriction, creating a better sound out of that 3.6-liter, and it's also going to increase some performance, especially when it comes to throttle response in those higher RPM ranges, and you definitely will notice it when getting on the highway or whenever you are in those higher RPM ranges.Now, as far as sound goes, I'm gonna give this a three out of five on the loudness meter, with one being completely stock and five being incredibly loud. Now, I personally think that this didn't increase a lot of volume, it does increase a little bit of volume for that 3.6-liter, but it deepens the tone a lot, creating a more aggressive and throaty sound out of that exhaust system. Now, when it comes to the interior noise, you're really not gonna have a lot at all, making it very comfortable to drive around. You will be able to hear a little bit when you do get on the pedal, but if you are looking for an exhaust system that does that and doesn't bother you the rest of the time, then this is going to be a great choice.I personally think that this is a great system for the daily driver or somebody looking for a lot of styling out of the rear end, considering that this is going to have a polished dual outlet, which adds a lot of extra styling but it's also going to be quiet enough where it's not overbearing and still give you that deeper tone that you may be looking for out of an axle-back system. Now, I would like to note that I would not necessarily recommend this to someone who's doing a lot of technical rock crawling since this does hang a little bit lower than some other systems. However, in comparison to the factory one, this is going to give you a little bit of clearance in the back with that smaller muffler. This is really great for somebody who's not doing a lot of technical off-roading, really daily driving their Wrangler, or a lighter trail weekend warrior.Now, with that being said, this is gonna come in at roughly $300, making this a pretty affordable option for a quality cat-back system. Now, you can tell that there's a lot of detail in the design, we have some really good welds going on, and, again, this is going to create a really nice noise out of the Jeep, it's not gonna be raspy, it's not gonna be droney in comparison to some other choices. Now, in comparison to some other options for axle-backs on the page, they may be just set up a little bit differently, they may have a more compact and more straight-through style muffler that's going to increase the sound, they may have a black tip, or they may have a high-clearance design that will take away this axle-back completely and tuck it up against the frame, which will be more for that off-roader.So, it kinda comes down to your personal preference in the design as well as the look. But, again, if you are looking for something that's going to keep it quiet when it comes to interior cab noise, still give you a deep and aggressive tone on the outside while creating a very clean and custom look on the back, then this is gonna be a great choice to take a look into. As far as install is concerned, I'm gonna give this a one out of three wrenches on the difficulty meter. You're gonna need a couple of basic hand tools to get the job done and probably about two hours worth of your time. Pretty easy job, in my opinion. So, speaking of that install, let's jump into that now.The tools that I used for my install were an exhaust hanger removal tool, a ratchet, a 10-inch extension, a 13-millimeter ratcheting wrench, 13-millimeter swivel socket, a 15-millimeter deep socket, an impact wrench, and PB Blaster. So, our first step to removing our axle-back is to remove the hangers. Now, I personally like to remove the hanger from the frame instead of removing the axle-back from the isolator itself. There's a little bit more room to work with, especially with the axle-back being so big. So, for this, you're gonna need a 13-millimeter ratcheting wrench and a 13-millimeter socket or swivel socket. Now, there's gonna be two bolts on the hanger on each side. So, we're gonna have one that's mounted to the frame and then one that's mounted to the frame bracket that's up and a little bit hard to see. I'm gonna start with the one on this side that goes into the direct side of the frame. I'm gonna use that 13-millimeter ratcheting wrench. We're gonna go ahead and remove that.Now, for this, you'll be able to see the back of the bolt, it's up on that bracket up at the top. I'm gonna be using a 13-millimeter swivel socket and a 10-inch extension to go over the sway bar to reach the head of the bolt. Now, once those two bolts are removed, you can probably see that there is a little hook here. Now, the hanger will stay in place if this is hooked onto that frame bracket. So, we're gonna do the same thing on the other side and leave this still hooked into that bracket. Now, because there's a little bit more room on this side, you can go ahead and use that 13-millimeter swivel socket with the extension on this side bolt here. With those hangers still hooked into the frame brackets, we can loosen up our clamp at the back of our axle-back using a 15-millimeter socket. What we can do at this point is now unhook those hangers from the frame brackets and wiggle our exhaust off.So, before we hop into the rest of the install, I wanted to stop down and show you guys a couple of the similarities and differences between our factory exhaust system and our new option by RedRock here and show you why this RedRock axle-back is going to give you a number of different benefits over your factory system. Now, starting off with the muffler, obviously, you can tell that there's a big difference. The one from the factory is going to be big, bulky, and baffled, and very restrictive in comparison to the smaller, and more compact, and more straight-through style option that we have with the RedRock. Now, this is going to increase your performance, create a better sound out of your Wrangler, and just overall be a little bit more beneficial when it comes to airflow in comparison to the factory.Now, speaking of airflow, over on the factory exhaust, you can see that the over axle pipe is pinched. Now, that's something that's not going to happen over on the RedRock one. Again, this is straight through style and it is going to allow some less restriction and better airflow, just improving that performance overall. Now, what I really like about this and the big takeaway from these two exhaust systems is that the factory exhaust system is going to have a single outlet with no tip, it's really not gonna be the best as far as styling is concerned, but when moving over to this new option by RedRock, as you can see, we have a dual outlet with a large polished tip. That's gonna help out with styling, create a clean and classic look out of the back end of the Wrangler.Now, this is also going to be a higher-quality material, made of a 409 stainless steel material, in comparison to the factory one which is made of a steel material. So, the stainless is going to hold up for a longer period of time, of course if taken care of, but that is going to allow a longer lifespan and allow a better look over time in comparison to steel that will rust over time. Lastly, this is going to have factory style hangers, very similar to our factory ones. There is a little step-down or a tapered edge to ensure that this is going to hold in place while this is on your Wrangler, and it even comes with a clamp, so you don't have to swap over the factory one, making this a one-stop-shop. So, what do you say we go ahead and install our new system?So, since we removed our full hanger, we do need to swap it over to our new exhaust system. So, I have a little bit of PB Blaster, this just makes it easier to take the hanger off because rubber on metal doesn't really want to come off as easily without a lubricant. So, I'm just going to spray a little bit of that, take my exhaust hanger removal tool, and remove that from the exhaust itself. The same thing on the other side. And now, since this already has a little bit of lubricant on it, what we can do is just slide this on to our new system. Now, you wanna make sure, obviously, that the flat part is facing outward. That's going to allow it to attach to our frame a little bit easier and correctly. So, once those are on there, I'm also, while we're here, just going to put this clamp on here. And then, that'll be ready for us when we mount this up. So, let's head over to the Jeep and secure this down.So, we can start by attaching it to our cat-back piping. There is gonna be a little cut-out for that notch on the pipe there. But once that's on there, it's gonna kinda hang in place. So, really, all we have to do at this point is hook these onto our frame brackets and get these in a position where we can secure them down. So, I like to hook it there first because it'll stay in place roughly. It's all we have to do. Right. Now, we can grab our factory hardware and secure those just like we did when we took them out. So, I like to put a little bit of pressure on the exhaust just to loosen this up, to make it easier to secure down. You can see it a little bit better now that there's not a big muffler in the way. I like to get them hand threaded as much as possible. Then, we'll tighten them down in just a second.Then, we can take our 13-millimeter socket. At this point, you don't necessarily have to use the extension to go over the sway bar, but since we used this before, we can just go ahead and use that 13-millimeter swivel socket and that extension just to tighten it up. Use that 13-millimeter ratcheting wrench, tighten up this side. We can repeat that for the other side then. Then, we can tighten up our clamp. I'm gonna be using the same 15-millimeter socket that we used before. So, after everything's all tightened up, then we'll be all set to go.So, that is going to wrap it up for my review and install.
