      Ryan: Swapping out your exhaust to a factory system is a good idea if you're looking for a lower exhaust note as well as some additional exhaust volume. The Magnaflow Performance Series Cat-Back Exhaust is going to give you that, but also change the aesthetics of your Jeep by having this dual outlet exhaust system with the polished tips as opposed to the factory single outlet. This system is going to be a little bit louder and a little bit lower than some of the other cat-back systems on the market because this doesn't just replace your muffler but it actually replaces the factory resonator as well. Now, of course, there are louder systems out there. There are systems that delete the factory resonator, delete the factory muffler and just replace the resonator location with a bullet style muffler. There are systems that have all of that and then are a dump, so of course, those are going to be louder. This is going to give you a more round, a more refined sound while still being louder and lower than that factory system is. This system is also made of a 409 stainless material, so it's a very high-quality stainless that's going to do a great job of resisting rust and corrosion, but all of that means that it is also going to be more expensive. It's more expensive because of the material. It's more expensive because it includes both a muffler and a resonator and it is going to be made, of course, by Magnaflow which is a company known for making a high-quality system so you're also going to get a high build quality. So if you have the budget for this system, around $900 or more depending on whether you go with this polish or with the black version of this, I think this is going to be a really nice option. So this system has a couple of different parts to it. Starting at the back, of course, you're getting this dual outlet muffler and this is a straight flow through muffler which, again, is going to be what gives you that low and louder exhaust note and you are gonna see these two tips that are polished and welded right onto the muffler poking out the back of the Jeep which is going to give you that more aggressive look. From there, you have the rest of the piping. This is going to be your over axle pipe. This is going to be an extension pipe that you're only going to use on your four-door Jeep, but again, all of the piping has made of that high-quality 409 stainless. It's all going to be 2-1/2 inch diameter mandrel bent tubing and what that essentially means is where there's a bend like this, there's a piece on the inside and the outside of the tube which keeps the tube from collapsing, so you get that nice flow. You're not getting any restriction in your exhaust tubing.Up here, you do have your resonator, which can be considered to be almost a second muffler or a pre-muffler. This resonator, as well as this muffler, work together to give you that refined, however, also louder and lower exhaust note than you would get from the factory. So to get this installed on your Jeep is a one out of three wrench install, but I will say it'll take you probably around two hours by the time you get the factory system removed and this system installed and it could be a lot more than that if you have a lot of rust on your Jeep. Man: First thing we're going to do is loosen the clamp right here at the resonator. It's a 15-millimeter nut. Got a 15-millimeter socket on my impact gun here. We'll go ahead and get this loosened up. Next, we're gonna move back to the backside of the Jeep here. Right at our muffler, we're gonna loosen this clamp. It's also a 15-millimeter. From there, we can then remove our muffler and then the rest of the exhaust system.All right, we're ready to remove our muffler now. I'm gonna spray both hangers with some WD-40. It's gonna help me pop them out of the hangers. I do have a hanger removal tool. If you guys don't have one of these, you can use a pry bar or a screwdriver. And we'll do the same thing on the other side. I'll spray it down. I might have to use a pry bar on this hanger. And we're now ready to remove our muffler. I'm gonna shimmy it out of the pipe here. Next, I'm gonna release this hanger off of the over axle pipe. I'll spray it down with WD-40, and using my hanger tool, we're going to pop this guy right off. And this is our last hanger that we need to release, right in front of the resonator here. I'm gonna use a pry bar to get this one out. We're now ready to remove the entire over axle pipe. I'm gonna tap on the resonator with a dead blow here and we should be able to take this out in one piece. We're gonna start off by installing our resonator. Don't forget to put your clamp on. I'll get my clamp started here. We also need to transfer over our rubber isolator because that's just gonna pop on there and then we can go ahead and get this guy installed. Next up is the extension pipe. We're gonna slide this right over our resonator with a clamp. Next up is our over axle pipe. This is gonna get slipped into the rubber isolator up top. And again, don't forget to put your clamp on the end. I'm gonna get this started in the hanger first and then slide it in the pipe. It's going to make it a little bit easier. We're now ready to throw up our muffler up in place. I'm going to get the pipe started first over here and then from there, I will get some hangers started. I'm gonna start with the right side over here and next, we're gonna go for the left side. So we're gonna go through and tighten all our clamps down now. I have a 15-millimeter socket on my impact gun. Ryan: So that's my review of the Magnaflow Performance Series Cat-Back Exhaust fitting all 2012 and up JKs that you can find right here at
