I'm Ryan from extremeterrain.com, and this is my review and installation of the MagnaFlow Performance Cat-Back Exhaust System, fitting all 2007 and up JKs. There are a few different versions of this system available, one for those of you with the 2007 to 2011 JK, and one of those for you with the 2012 and up. And of course, there's also different systems available for those of you with a two-door and a four-door body style, so make sure you order the right system for your Jeep. Today, we're gonna talk through the installation of this system, which is a very simple one out of three wrench installation. We're also, of course, going to talk about the sound and the tone that you'll get from this system and a few of the other features and the construction.This system is for those of you who wanna change up the sound of your Jeep. Now, if you are just looking to get a different look out of your Jeep, there are axle-back systems that have dual outlets that will do that. If you're looking to make your Jeep more off-road-friendly by getting rid of a lot of the piping and the big factory mufflers so there's less to crush off-road, there are high-clearance systems available as well.This system is almost an exact replica, as far as the piping and where everything sits, as your factory system. However, this is going to sound a lot different from that factory system. This will give you a much lower exhaust note and a lot more exhaust volume, especially at the higher RPM ranges. Now, this system, if you have a 2012 and up JK that has a factory resonator, this comes with a factory-style resonator, although it is designed to flow more free and, of course, produce a little bit more volume. But there are systems out there that will delete this resonator, there are systems out there that will delete the muffler in place of a bullet-style muffler where the factory resonator was, so there are a lot of different options.This system is not going to be quite as loud as those that either delete the factory muffler and have a bullet-style muffler in place of the resonator or even those that have a factory-style muffler with a resonator delete. This is going to be a little bit more quiet than some of those, but you are still going to get that lower exhaust tone. Now, because this system does that have the resonator, the muffler, all of the piping from the cat-back and this is a well-built system made by MagnaFlow, this is going to be more expensive than some of the other systems available for your JK. So if you have the budget for it and this provides the sound you're looking for, this is going to be a really well-built option.This exhaust system is built from stainless steel, which means it's going to hold up against rust and corrosion a lot better than an aluminized steel system would, but that's also where part of the cost comes from. Stainless is a much more expensive material, so this system is going to be more expensive than some of the others available. This is made from 16-gauge stainless steel that is 2.5 inches in diameter, and all of the tubing is mandrel-bent, which means there's a piece that goes on the inside of the tubing and on the outside, where all of the bends take place, to help keep the tubing from collapsing, which can cause a choke point. With the system wide open like this, it will provide a much better flow out the back of your Jeep and not cause any back pressure, which can hurt performance.The tip on this system is 3.5 inches, so it's a little bit bigger than the rest of the piping, giving a nice look out the back of your Jeep. As I said before, this is a single outlet exhaust, which is very similar to the factory style, as opposed to some of the other aftermarket systems that are available, which will be a dual outlet muffler, which will even further change the look out the back of your Jeep. The 2012 and up JK models will, as we said before, come with this factory-style resonator and the muffler and all of the piping with the tip welded in place all ready to install and ready to go, where the earlier JKs that didn't have the factory resonator will not come with one.Installation for this system is a very simple one out of three wrenches because it is designed to use all of the factory hangers and install in the Jeep very, very simply. The first step is, of course, removing your factory system, and that's the only place that you can add a little bit of time to your install. Exhaust systems do like to get rusty, so I definitely recommend spraying all of the clamps and the hangers well ahead of time with a good penetrating oil to help speed up this assembly. You can start from the back, removing the clamps and then removing all of the hangers from the rubber hangers on the Jeep, getting all of the factory system unbolted and removed all the way up to the cat.From there, you'll go ahead and install first this resonator pipe by hanging it on the factory hanger and sliding it over your factory piping using the clamps that are included with this setup. Then you can install the over axle pipe and finally the muffler. Again, everything goes right in its factory spot using the new clamps that are included, making this install very, very simple. To get this done, you will probably wanna raise the Jeep up a little bit to make it easier to get under underneath of unless, of course, you have a big lift and big tires. You will need some traditional hand tools and a good penetrating oil, but other than that, you won't need any specialty tools to get this job done. And you can probably get it done in about two hours or less.MagnaFlow is a big name in the exhaust industry, and they're known for making a high-quality product. You combine the build quality that you get with MagnaFlow with the fact that this is made of stainless steel tubing, which is a premium material and is also more expensive, and the fact that, if you're getting a 2012 and up JK exhaust, it comes with a resonator, so there's just more material here, all of those things add up to this being one of the more expensive systems on the market. But I think you're getting great build quality, and if you like the sound of it, I think it's a home run. If you are looking to save a little bit of money, there are certainly other systems on the market that will give you a slightly different exhaust tone and save you a little bit of money. So it really comes down to what sound you're looking for out of your Jeep and if you have the budget for this system.So if you're looking to swap out the factory cat-back on your JK for an aftermarket one from MagnaFlow to provide more exhaust volume as well as a lower exhaust note, this is going to be a really well-built option. So that's my review of the MagnaFlow Performance Series Cat-Back Exhaust System, fitting all 2007 and up JKs, that you can find right here at extremeterrain.com.

Construction. Magnaflow uses highly polished, 100 percent stainless steel to construct their Street Series Cat-back, straight through exhaust system. This system withstands rust, corrosion, and physical damage with its 16 gauge walls.

Installation is straightforward with included band clamps, also of stainless steel.
This Magnaflow muffler bestows a deep, smooth exhaust note on your Jeep besides its practical benefits. Improved aspiration generates fuel efficiency, adds several foot-pounds of torque, and develops higher horsepower.

Best Wrangler exhaust system
Great look and fit. Quality product, easy installation and powerful but reasonable exhaust tone. Very happy with this unit. If you have an aftermarket rear bumper or tubular rear bumper, check to ensure the exhaust tip will clear. It's a perfect fit with factory bumper.Helpful (15)

You get what you pay for
Once you get the original junk out, it goes together in about 20 minutes laying on your back in the drive way.Helpful (13)
What rear aftermarket bumper goes with this cat-back exhaust system. I've installed the Magnaflow #16666 on my 2011 JK Rubicon and exhaust tip clearance is 5/8 inches from the frame rail. It fits perfect with the stock rear bumper.
Any aftermarket rear bumper would work with this Magnaflow exhaust. Modification to a bumper nor the exhaust would be needed for proper fitment.
Am I correct in assuming that with a resonator included with the package that this system will not have a drone? I have a 2017 Unlimited Rubicon. Additionally, will it clear an AEV rear bumper.
The Magnaflow Performance Series Cat-Back Exhaust is designed to eliminate exhaust drone, and should exhibit no drone, unless the cats have been deleted. We have not tested this with the AEV bumper, as we do not offer this bumper, however we believe this will clear.
Does this exhuast kit meet CA regulations?
Hello, the Magnaflow Performance Series Cat-Back Exhaust (12-17 Wrangler JK 4 Door) is Legal in All 50 U.S. States, so it will meet CA regulations.
