    Review & Installation Video

    Review & Install Video

    I'm Ryan from ExtremeTerrain.com, 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 ExtremeTerrain.com.

    Do you know the weight difference from the OEM to this system? I would think a good bit lighter?

    Does the muffler tuck up above the frame so it's not a impact risk?

    DonaldG

    • Yes, the Magnaflow OffRoad Pro-Series Cat-Back Exhaust helps cut and tuck up the exhaust length to prevent damage when off roading.

    How is this exhaust work with water fording? Hello. I have a 2014 JKU Sport and interested in this Magnaflow Pro-Series cat back exhaust. I like to play in water and was wondering since this exhaust is being shorter than the factory one how vulnerable does it make the engine to water damage? Thx.

    • The Magnaflow OffRoad Pro-Series Cat-Back Exhaust (12-17 Wrangler JK 4 Door) like other exhausts blow out and does not suck in, normally, so the length should not be a problem. The only problem is if you stall while the pipe is submerged water can get sucked in which will happen with any exhaust.

      Drone and fittment is awful

      Overall the product is built with quality however it sounds nothing like what is shown in the videos. The drone while driving is awful and almost unbearable with the top and/or doors. Fittment isn't great either due to it being pushed right against the from and the end of the exhaust sits about 3 to 4 inches below the rear axle. So much for it being a high tuck exhaust. Overall I was pretty disappointed with the exhaust.

      loud and beefy

      I shopped around for a while I search of the perfect exhaust for my Jeep and I found it. It is loud but it is a Jeep so why would you want anything different? it also has a nice tone. it does not sound like an import. installation was a breeze, after a solid hour or two of removing the old one.

      Great exhaust

      This took me 2 hours to install and the majority of that was removing the old exhaust. Great sound at idle and at higher RPM's. Installs nice a tight using existing locations and creates great clearance in the rear by eliminating the trash can muffler that used to sit there.

      Badass sounds and awesome product

      The sound is pretty good, louder than I thought it was going to be, not a problem. The quality is 9/10 it can always be better. The installation was a pain, not because of this product but because of the old one. The removal took 3 hours and the installation took maybe 45 min. I did it all by myself too. I've only been driving it for less than a week now so didn't notice anything with mpg but it definitely has more horsepower. I would recommend this product. I know this review is just about the product but I want to give a shout out to extremeterrain.com the delivery time was better than amazon prime. less than 48hr I had the item.

      Great quality, simple install, (and uninstall)..... took it off after just 2 days, the drone inside was ridiculous. Sounded more like a trail damaged exhaust than a performance exhaust.

      Review from Magnaflow Off-Road Pro-Series Cat-Back Exhaust (07-11 Wrangler JK 2 Door)

      Great upgrade!

      Love the tone of this exhaust.... It's definitely noticeable, but low enough that it doesn't sound like a fast and furious car. I added this exhaust, CAI and throttle body spacer. I've gained almost one MPG running a 91 octane tune on 35s on my 2011 2 door manual. Still have the dead spot in the pedal, but my Jeep does feel a little more responsive. It sits in front of the rear axle so frees up a ton of room underneath where the factory exhaust was mounted. (Had a local shop install for $100) Great purchase!

      Install was quite easy (removing old exhaust took longest). Sounds great under load, but a little buzzy at normal cruising speed. Although, it is a 6 cylinder so that's expected. Overall very satisfied with the results.

      This exhaust is awesome, as is true for every magnaflow product I've ever used. The exhaust wakes the motor up for sure as it scavenges gases way better than stock. The exhaust note is crisp, clean, and deep for a V6!

      Very easy install once you get the stock exhaust out. Be ready with a lot of rust penetrating oil to get the stock exhaust off. Muffler has great sound and looks much better than the stock trash can that hangs under the car.
