      Video Review & Installation

      I'm Ryan from, and this is my review and installation of the Magnaflow Offroad Pro-Series Cat-Back Exhaust, fitting all 2007 to 2017 JKs.Now, there are two different versions of this exhaust: one for those of you with the 3.6, and one for those of you with the 3.8-liter. And there is, of course, a version for those of you with the two-door and the four-door unlimited JK. So, make sure you get the right exhaust for your Jeep. Today we're going to talk about the way this exhaust sounds and how to get it installed.This exhaust system is going to be for those of you who want a lot more volume and a lower note out of your Jeep. Now, nothing is going to make your V6 sound like your V8, but a nice short exhaust system like this that gets rid of the factory resonator and muffler, replacing it with one straight flow-through muffler will definitely give you a lot more sound. And the fact that you have fewer components and a lot less piping means there's a lot less to crush when you're in an off-road scenario. Now, this is mostly for you guys who are doing a lot of off-roading and want the benefits of a high clearance exhaust that's tucked up out of the way, however, if you just want the sound and the volume, this system can be run in an on road Jeep as well.This cat-back system is made of stainless steel, so it's going to hold up pretty well to rust and corrosion, and it's going to last a good long time. As you can see, this does replace everything from the cat back on the Jeep. It's going to replace your factory resonator and your factory muffler, and it is a lot shorter than that factory exhaust system. In fact, the tip to this system dumps in front of the rear axle instead of behind it all the way at the rear of the Jeep. So, everything from the fact that you're getting rid of the factory resonator and muffler for one muffler, the fact that it's a much shorter pipe, all of these lead to a much louder and more aggressive sound.This system will install on your Jeep very easily. That installation process begins by removing your factory exhaust system, which is done by removing a couple of clamps and popping a couple of factory rubber exhaust hangers loose. Once you have that factory exhaust removed, you can go ahead and install the new one, leaving all of your clamps loose until you have everything lined up and in those factory hangers, then going back and tightening up all of the included clamps.Now, your factory exhaust can get very rusty, so I would recommend spraying those clamps well ahead of time, and also spraying your factory rubber hangers to make them easier to remove. That's the only part that can add time to your installation, is rust or having some hangers that just won't budge. Regardless, the whole installation shouldn't take you more than an hour, and you won't need any specialty tools, just some traditional hand tools.This system is priced right around the middle of the road for a cat-back system. Magnaflow's been around for a long time and they have a good name in exhausts. They make a high-quality component that is going to definitely give you some more exhaust sound and a lower exhaust note. So, if you're looking for a high-quality system and you have the budget, I think this is a great option.So, whether you're looking to replace your factory exhaust system that was smashed on the rocks, one that just rusted out, or you're just replacing your system to get some more sound and a lower exhaust note, I would definitely recommend taking a look at this system.So, that's my review of the Magnaflow Offroad Pro-Series Cat-Back Exhaust, fitting all 2007 to 2017 JKs, that you can find right here at
