      Video Review & Installation

      Hey, guys, so today I'm here with the Magnaflow Street Series cat-back exhaust system, fitting all 2018 and newer JL Wranglers with the 2.0-liter engine. Now, cat-back can offer you a number of different benefits and this option by Magnaflow is going to do just that. Now, this will do a really good job at opening up a lot of airflow, getting rid of a lot of restriction, which will essentially boost your horsepower and torque numbers in those higher RPM ranges and create a more aggressive tone out of your 2.0 liter. As far as volume and loudness goes, I'm gonna give this a two out of five on the loudness meter with one being completely stopped and five being incredibly loud. Now, this is Magnaflow Street Series and that is their more quiet option and that's exactly what you're gonna get from this. It is gonna do a really good job at creating a more aggressive tone or a deeper tone out of the 2.0, however, you're not getting a lot of volume with this system.Now, that's gonna make it perfect for that daily driver who does not wanna hear their exhaust all the time or doesn't want something that's incredibly loud. Wants to keep it comfortable inside the cab area with no drone, thanks to the resonator mounted upfront, making it a perfect entry-level exhaust system, like I mentioned before. This is also just gonna be great for the Jeep owner who's in search of a good looking exhaust considering that this feature is a 4-inch polish tip, a dual outlet, and even a polished muffler, giving a very clean look to the back end of the Jeep. Now, with all that being said, this is gonna cost you roughly $900. And in my opinion, I think you're getting what you pay for with the quality construction as well as the high-quality materials that are included in this kit. Comparing it to other exhaust systems on the page, this is set at a pretty average price point. Now, some less expensive choices are usually just going to be either made of aluminized steel instead of a high-quality stainless steel option like this.Or they usually will be for those high touch choices, more for the offroader and more for somebody who's really concerned about their departure angles and not necessarily concerned about looks. Again, in my opinion, I think if you're looking for a good looking exhaust system as well as something that's going to make your 2.0-liter sound a little bit more aggressive and not bother you on your day to day drives, then this option is gonna be a great one to take a look at it. Install is gonna be a two out of three wrenches on the difficulty meter, taking you about two hours to get the job done with some pretty basic hand tools. So, speaking of the install, let's jump into that now. Tools that I used for my install were a pry bar, a 10-inch extension, 3/8 inch drive, and quarter-inch drive ratchet, an impact wrench, a hanger removal tool, and a socket set ranging from 18-millimeter down to 10-millimeter. So, our first step to this install is to start by taking off our muffler, I'm gonna start with the hangers and I find it a little bit easier to take off the hangers themselves just because there's not a lot of room on the side of our muffler to fit a hanger removal tool.So, you're gonna need a 13-millimeter socket as well as a 13-millimeter ratcheting wrench in order to remove those two bolts that are holding the hanger on. I'm also using a 10-inch extension to reach the top bolt that's up on top of the hanger and just because it is a little bit hard to reach. Then we can remove the bolt on the side, just because there's not a lot of room I'm gonna use a 13-millimeter ratcheting wrench. And then this hanger will stay hooked onto that frame and then we can do the same thing on the other side. Next, we can loosen up the clamp on the over axle pipe, I'm gonna be using a 15-millimeter deep socket. Then we can wiggle off our exhaust. Next, we can loosen up the clamp up at the cat-back piping. I'm going to be using a 13-millimeter ratcheting wrench. Now that that's loosened up and able to be disconnected what we can do is remove the exhaust itself from the hanger. So, right behind your driver's side spring, you will have a hanger here and an isolator.This is not removable, it's welded to the frame. So, what we're gonna have to do is use a hanger removal tool and go ahead and push the exhaust out of the isolator. All right, so once it's removed, now we can wiggle out our exhaust piping. So, the exhaust is hitting our spring and the subframe is in the way. So, what I'm gonna do is just to loosen up the bolts on either side of the subframe as well as the back. And then it is connected to this bracket here, so I'm just gonna remove the two 10-millimeter bolts that are holding it in, so we'll be able to drop the subframe and wiggle our exhaust out. So, first I'm gonna use an 18-millimeter socket and loosen up the four bolts that are holding on our subframe. Next, I'm gonna take a 10-millimeter socket and remove the 2 bolts that are holding on the backside of this bracket. Once those are out, we'll be able to drop the subframe down, now we can remove this bolt over here on the side and wiggle our exhaust out. So, now that our subframe is kind of out of the way, what we do is wiggle our exhaust out.Before we open to the install I wanted to a stop down and tell you guys a little bit more about this Magnaflow Street Series exhaust system and what benefits that you're gonna see out of this over our factory setup. Now, this is gonna be a big step up in construction, as well as materials being made of a stainless steel material with mandrel-bent tubing, and that's going to be a lot more rust-resistant and hold up for a longer period of time in comparison to our factory steel material. Is also gonna have factory style hangers on it to ensure a good fit as well as high-quality weld to ensure again that this is going to hold up for a long period of time and look good while doing it. Now, as you can tell on the factory piping that over axle pipe is pinched which does cause a lot of restriction and the factory style muffler and resonator are baffled as well and also cause a lot of restriction. But when moving over to this system, you're getting straight mandrel-bent piping, you're also getting a high flow muffler as well as a straight-through style resonator again, freeing up a lot airflow.And that's gonna help you out in the performance department with some better horsepower and torque gains because of that better airflow, but it's also going to help you out in the sound department as well with a more aggressive tone to your Wrangler. Now, not only is it just going to be very functional, but it's also gonna give you a good look to your Wrangler as well with the large four-inch polished tips and the dual outlet in comparison to our single outlet that we see on our factory exhaust system. This is gonna give you a very polished look to the back of your Wrangler and bump up your styling, especially for you guys out there that are a fan of that dual tip. What I also really like about this new exhaust system is that it is a lot more compact. Now, that is going to be a good look as far as just making the exhaust system look a lot sleeker than our factory one, but it is going to save you a little bit of room for you guys that are going out on the trail. Now, this is also going to come with everything that you need in order to install it, all the clamps and again those factory style hangers for a good fit. So, let's go ahead and install our new exhaust system.So, first what we're gonna do is take off our clamp. This is the clamp on the resonator piping, there is a little tab here that you might have to bend out of the way. What we can do is just add that to our new exhaust system, then we can head over to the Jeep. What we can do first is attach our resonator piping with our factory clamp. We're just going to attach this here, wiggle it into place, make sure that the clamp is sitting over both pipes. And then what I'm gonna do is just tighten it up with a 13-millimeter socket. Now, we'll be able to adjust this just a little bit later but I wanna make sure that this is staying in place. So, now that that's on there, what we can do it our subframe back up and just reattach it with the 2 bolts on the side and the two 10-millimeter bolts on this. Then tighten up the two back that we loosened as well, then we can just reattach those two 10-millimeter bolts on the bracket. What we can do next is attach our over axle pipe, I'm going to take our provided clamp, back on here, wiggle this over our resonator piping. What we wanna do is line this up to get into the hanger.What we can do now is transfer over our factory hangers on to our new muffler there. I'm going to use a hanger removal tool in order to take these off. Put a little PB blaster on there just to help the hanger come off. Same thing for the other one. What we can do now is grab our new muffler, making sure that the clamp that's provided is on the end, line that up with our over axle pipe. And then what I'm gonna do is actually hook these hangers onto the frame, making sure that everything lines up correctly. What I'm gonna do just to hold this in place is take one of the factory bolts and thread that into the frame, and same for the other side. Now, while this is mounted up, we can install our other bolt on our hanger. It might be a little helpful to push up on the exhaust, just to align everything up. Great. Now, we can tighten everything down. We can start by tightening down our hangers, I'm gonna be using a 13-millimeter socket for both the side and top bolt. Same for the other side.Then we can tighten up our clamp, making sure that it's sitting over both of the pipes of the 15-millimeter socket. Next we can tighten down the clamp that's holding on our resonator piping to our over axle piping with the same 15-millimeter socket. And last but not least, we can head up to our first clamp up here, a factory-style clamp, tighten that down with a 13-millimeter socket. After everything's tightened up, then we're all set to go. That's gonna wrap it up for my review and install. Make sure like and subscribe, and for more videos and products like this, always keep it right here at
