It's Joe from ExtremeTerrain. In this video, we're going over the Injen Dual Muffler Axle-Back Exhaust with Black Tips fitting all '18 and newer 2-liter or 3.6-liter JLs. Now, this is gonna be an awesome upgrade for you if you're looking to pay a little bit extra for a high-quality USA-made stainless steel muffler system that's going to add awesome blackout looks and moderate volume to your Jeep.So, as you guys just heard, this is going to be a huge upgrade over the factory exhaust. In my opinion, a lot of that is gonna be tone. If you're looking for volume, this is probably not gonna be the loudest system out there. It's definitely not the quietest. And with that said, I'm gonna give it a solid three out of five on our wake the neighbor scale. As far as tone goes, like I said, I really enjoy this one. It's got a little bit of a burble on the upshift as well, which adds a little bit of a race car feel to that 3.6 Pentastar.So, let's dive into exactly what is gonna be making that noise. So, let's talk a little bit about build quality. This kit is gonna be 304-grade TIG-welded, mandrel-bent stainless steel. Now, just to break that down a little bit for you guys, TIG welds, they look a little nicer. They're a little bit stronger too. However, they take a lot longer. Injen definitely did not have to do that, but it's a nice touch, and I appreciate that. Mandrel bends, all that means is throughout the length of any bends here, you're not gonna have any wrinkles in that tubing, but walls in the tube, they're gonna be nice and smooth, allowing your exhaust gases to escape as fast as possible and that's exactly what you want out of any exhaust kit. 304-grade stainless, that is pretty much gonna be the highest quality stainless you'll find on an exhaust system. If you're looking to keep your Jeep for a really long time and you're looking to have an axle-back hold up, that is going to be a great offering, and this one definitely checks all the boxes in terms of build quality.Now, just to add on to longevity, it does have that awesome black ceramic powder coating on there, which adds to the looks, and it's going to serve as another layer of protection over the top of that stainless steel. This kit is going to start off with some 2.5-inch diameter piping just like the factory stuff. From there, though, we have a straight pipe, again, keeping those mandrel bends right here until you get to the Y-pipe. This is gonna be a dual muffler setup, so the exhaust gases are gonna have their own muffler going to this tip and their own muffler going to that tip. This is going to be their straight-through muffler. That's where most of our sound is gonna be coming from, and again, huge upgrade over the factory stuff. They even add to the looks by embossing the Injen logo right here on the side.Out the back of those mufflers, we have 3-inch diameter tubing, and at the end of those, we have some awesome black chrome tips. They're angled, they're rolled over, and they have the Injen logo on the side, and they look awesome. Perfect compliment to any blackout build. Now, one thing I do have to mention with an exhaust like this one is this is not gonna be CARB-certified, so if you live in a state that adopts those emission standards, California Air Resources Board, this is not gonna pass smog. We do have some other options out there that will. However, this one is not gonna be for you. If you live in a state that doesn't abide by those rules, this is gonna be just fine.So, next up, let's talk a little bit about pricing. Now, it's gonna be expensive, but again, you guys could probably gather the reason for that. Build quality and materials here are gonna be bar none. Also, this thing is made right here in the USA. It also includes a limited lifetime warranty, so expect to pay top dollar for something like this. Simply put, it's going to cost you right around 750 bucks. But if you're looking for the top-of-the-line with a good tone and a little bit of a burble on the upshift, this is a great option.Moving right along, let me show you how to get this thing installed on your Jeep. The JL muffler is pretty easy to work with as far as removal goes, and getting this thing up is going to be the reverse of that. I'm gonna give this an easy two out of three wrenches on our difficulty meter. Should take you at most two hours if you come with the right tools. So, without any further ado, let me show you what tools you will need and how it's done.Tools I use for this install will include the impact, ratchet, a pry bar, 17 and 15-millimeter sockets, an 8-millimeter Allen key, and a spray lubricant like PB B'laster can help you get these hangers moving.So, removing a JL muffler, this is gonna be pretty simple. It's held on with two rubber hanger isolators, one on either side of the muffler, and there's another one over there by the tailpipe, so two in total, and then a 15-millimeter clamp up here on the over axle pipe, which we're gonna loosen up second. First thing we're gonna do is pop the hangers out of their isolator. Here's how I like to do it. If you just grab a pry bar and get that situated underneath the Jeep, go ahead and push to the side here. That's going to pop off just like so. Same thing goes on the other side. Now, one thing I always like to note, now that we have the muffler hanging down a little bit, if you do struggle with this and you need to remove these, it's held along with a couple of 13-millimeter bolts. There's one here and one up at the top facing the other way. You could always loosen those up with the 13-millimeter socket and a U-joint, and this thing will come down as one. Then you can transfer those over to the new muffler. And this is the clamp that's holding on our muffler now, 15-millimeter socket to loosen that up.All right. So, now that we have our factory muffler removed off of our JL here, now is the perfect time to bring in our new Injen muffler, put the two next to each other, and draw some comparisons between both of these kits. Now, the first thing I want to talk about is the stainless steel used between both of these kits. Now, the factory stuff, that's gonna be 409-grade stainless steel. That's mid-grade stuff. You will see a little bit of surface rust on there, but it will never affect the structural integrity of this exhaust. However, Injen is gonna take that to the next level. They're going with a 304-grade stainless steel, which simply put is pretty much the highest grade you'll ever see on any vehicle exhaust out there, so really, really nice stuff. If you're looking to keep your Jeep for the longest time and hold on to your Jeep basically until the end of days, that 304-grade stainless steel is gonna be perfectly fine.Now, they take that to the next level actually by going with that black ceramic coating over the top of it, and basically another layer of protection, so if you're looking for longevity, this is gonna be a great pick. On top of that, the welds are a little bit better as well. Standard stuff, you have those blotchy MIG welds. Over here, you have the TIG stuff. They really didn't need to do that. It takes a lot longer to do a TIG weld than it does to do a MIG weld. However, they are a little bit cleaner, and they're a little bit more structurally sound as well. So, well done, Injen. This thing is definitely pretty stout.So, now just moving through our kits, we'll start with piping diameter. We'll work our way from the inlet all the way back to the tips. Both of these, gonna be 2.5-inch piping up here. However, a factory pipe does kind of sandwich itself out a little bit to make a little bit more room for suspension components. Injen, not a problem. They fixed that perfectly fine with just a straight-through pipe and some clever bends. Now, at that point, you get to the Y-pipe, which is going to split into our two mufflers. Before we talk about those, let's talk about the factory one. The factory one, you can see over here just how big, restrictive and heavy this guy is. We're changing that out for two straight-through Injen mufflers. Again, these are gonna be a huge upgrade. They're straight-through, so it's not going to resist the exhaust flow, and on top of that, they're embossed with the Injen logo on the side. That's where most of our sound is gonna be coming from, and it's a giant upgrade.Now, after the mufflers, we move into dual 3-inch piping. Now, comparing that to factory, we just have that 3-inch pipe just basically exiting with a slash-cut. Not the prettiest thing in the world. The Injen definitely fixes things here. We have dual 4-inch rolled edge slash-cut tips. They're black chrome. They have the Injen logo on top of them, and again, another giant upgrade.So, that's pretty much it as far as differences and similarities between these two exhaust kits. We're going to grab that Injen clamp that comes with our new exhaust. We're going to get this situated, and then we'll tighten everything down.So, first thing you want to do, go ahead and throw that clamp over the inlet pipe, and there's three spots we got to get this situated in. Number one, obviously the piping needs to go together, and two, we got to get this started in both of our hangers. Now, we're going to use a 17-millimeter socket to tighten down that clamp. Next thing we could do is throw on our exhaust tips, and once you have that lined up, you can tighten those down with an 8-millimeter Allen key. And we're gonna hit the same thing over here on the other side.So, guys, that's gonna do it for my review and install of the Injen Dual Muffler Axle-Back Exhaust with Black Tips, fitting all '18 and newer 2-liter and 3.6-liter JLs. As always, guys, thank you so much for watching. Make sure you keep it right here at ExtremeTerrain for all things Jeep.
