I'm Ryan from extremeterrain.com and in this video, I'm gonna tell you all about my picks
for a cat-back exhaust system fitting your 2007 and up JK.
Make sure you subscribe to our YouTube channel to check out more videos like this, as well
as more in-depth videos on each of the individual products that we're gonna talk about today.
So a cat-back exhaust system is going to be for those of you that are looking to get more
exhaust volume, as well as a lower exhaust note out of your Jeep.
Now, you can always go with an axle-back system, but if you need to replace more of your system
because it's rotted, rusted, dented, or whatever the case may be, or, in the case of some of
these systems, they're going to eliminate your factory-style muffler, and replace it
with a bullet-style muffler further up the exhaust system, then of course, you're gonna
have to go with a full cat-back.
So, if you're looking up the difference between axle-back and cat-back, axle-back is going
to pretty much leave the system as a factory system, just changing out the muffler, still
giving you a little bit more attitude if you go with a dual exist or black system.
It's definitely giving you a little bit more volume and a lower exhaust note, but if you're
looking for even more, then you're gonna wanna go with a cat-back system.
The systems we're going to talk about today for the most part are going to fit on the
2007 all the way up to the latest model year JK, so they are going to span the 3.6 liter
and the 3.8 liter engine.
Some of them are going to be engine-specific, so depending on the system that you choose,
make sure you pick the right one for your Jeep.
In that same vain, most, if not all of these systems are going to work with both a two-door
and a four-door JK.
Some of them will have an extension pipe that you'll use on a four-door and not use on a
two-door.
Others will require you to do a little bit of cutting if you're installing the system
on a two-door versus a four-door, but, for the most part, all of these systems will work
on both Jeeps, just a little bit of a different install.
Speaking of the install, most of these are going to be more or less a completely bolt-on
system.
I just said you might have to do a little bit of cutting if you're installing this on
a two-door, but if your system doesn't require cutting, there's going to be no other serious
modification to the Jeep.
You're not cutting anything up, you're not welding anything on.
These are going to be bolt-on systems, again, with that one little asterisk of possibly
a little trimming if you're installing a system on your two-door, but the product page will
be very clear on exactly what's necessary to get your installation done.
Now, are you gonna say that if we're talking about muscle cars, if we're talking about
trucks, even some times an exhaust system would be more of a performance part.
You would be opening up the exhaust, letting the engine breathe a little bit easier, which
will give you a little bit more power, and the same can be said for a cat-back system
on a Jeep.
However, any power gains that you're going to see are most likely at the top of art hammering
where we don't spend a lot of time in our Jeeps.
Of course, these things aren't sports cars so I wouldn't expect to get a huge gain in
power.
Maybe a little bit of a gain in MPG, but not a huge gain in power that you're really gonna
feel when you're driving down the road by installing a cat-back exhaust system like
the ones we're gonna talk about today.
What you are going to gain is a different look to your Jeep, you're going to gain some
additional clearance if you are running one of those high-clearance, rock-crawler style
systems that we're gonna talk about, and of course, you're going to get that lower exhaust
note and that louder exhaust as well.
So, the four systems that I wanna talk about today are the Magnaflow Performance Series
dual-exit cat-back system.
That's going to be a very high-quality system that is very much a factory-like system for
your JK.
It's going to include all of the same components that the factory system includes, just higher
quality, and of course, giving you a little bit more volume.
Then we're gonna talk about the Flowmaster American Thunder series that's going to be
a little bit less piping.
It's going to eliminate that factory muffler location for those of you that need a little
bit more clearance off-road, but is still going to dump after that rear axle.
Then we're going to talk about the Pypes High Clearance exhaust system that's going to dump
in the same location right after the rear axle, again, still eliminating that factory
muffler location for those of you that are doing some off-roading, and that system is
going to be a little less expensive than the others, but is still made of a very high-quality
material, so I think it's definitely worth speaking about.
And the last system we're gonna talk about is the Magnaflow Off-road Pro series cat-back
system.
That's going to be the shortest system that we're gonna talk about today that actually
dumps in front of the rear axle.
It's going to be the most simplistic, the shortest system, the least amount of piping
to get bend up on the trail, and, because it is so short, it's also going to give you
one of the more aggressive sounds of all four of the systems we're going to talk about.
So, let's get into them.
The first system I wanna talk about is this Magnaflow Performance Series dual-exist cat-back
exhaust system.
This is going to be the most expensive system that we're going to talk about today and the
reason for that is one, it' high-quality material, two, it's high-build quality, but three, this
is the system that is most similar to a factory system at least on a 2012 and up JK, and the
fact that it has both a resonator and a muffler in the factory location, so when you add all
of those things together, this is going to be a pricier system than the other ones that
we're going to talk about.
Their's is gonna be a little bit more strip-down and a few less pieces included.
But, if you are somebody who doesn't have the need for a really high-clearance system,
maybe you do a little bit of off-roading, but you're not doing anything real serious
on the rocks, maybe your Jeep stays on the street, so you're okay having this additional
piping, having still the resonator and the muffler in place, but you want something that
is going to be very high-quality 409 stainless material.
So, yeah, you'll get a little bit of surface rust on it, but it's not gonna rot out like
aluminized steel.
You're also going to get more flow through the system, a lot more exhaust volume, also
a lower exhaust note that we were talking about before.
This system is the polished version of the system.
It's also available in black, but as you can see here, it is the dual-exit system, so you're
going to have two tips out the back, definitely giving your Jeep a little bit more attitude
than it had with that factory set up.
This is one of those systems that will fit on the four-door and the two-door.
This is the extension pipe.
You just don't use this piece when you're installing this system on a two-door.
Of course, if you're going for the four-door to give you the additional length that you
need so no cutting necessary with this system.
Overall, you know for Magnaflow, you're getting something that is very high-quality from a
build quality perspective, and you can really tell that when you take this out of the box,
and you look at the welds, and how well-manufactured this whole system is as you combine that with
the fact that it's a high-quality 409 stainless, and that it is going to give you a very rich
and well-rounded sound.
I think this is definitely a win if you want a factory style system that's just going to
be a little deeper and a little bit louder and also very high-quality.
The next system is the Flowmaster American Thunder system and this is going to be different
from the Magnaflow we just talked about in pretty much every way.
So, this is not going to include a factory muffler in the factory location.
If you have a newer JK that has a resonator, this is not going to include a resonator that
goes in the factory location either.
What this system is going to include is the piping to get you from your catalytic converter
through this bullet-style muffler that sits pretty much where that factory resonator would
have sat, and then over the axle and out to the rear of the Jeep.
So, this is still going to be a rear exit behind the rear axle, but you're eliminating
a lot of the other stuff that's in the way that can usually get banged up on the trail.
Again, not having a big, bulky muffler right by the rear bumper is definitely going to
be a good thing if you're crawling on the rocks.
Because, the system is using a smaller bullet-style muffler, and again, eliminating the resonator.
If your Jeep had one from the factory, this is definitely going to be a louder sound than
you would get from that Magnaflow and a little bit less refined as well.
I'm not talking about drone, I'm not talking about anything crazy loud, but it is going
to have some more volume than the other system that we talked about.
Now, again, you're getting something from Flowmaster, which is a really well-known name.
They build a very high-quality product.
This is also going to be 409 stainless, so again, maybe a little bit of surface rust
on this, a little bit of surface oxidation, but you're not going to end up with a complete
rot through like you would with some of the much less expensive aluminized steel systems.
This is going to be a little bit less expensive than the Magnaflow that we talked about, again,
that had a lot more components, a lot more expensive.
This one is going to still be a little on the pricier side because you're paying for
the quality of the materials and also the build quality, but I do think you're getting
a lot for your money.
The next system is the Pypes high-clearance exhaust system and this is going to be pretty
similar to the American Thunder that we just talked about with a few differences.
So, this is going to be the same in the fact that it eliminates that factory muffler, it
eliminates the factor resonator if you have one and it replaces that whole muffling system
with a bullet-style muffler that resides where that factory resonator would right up next
to the frame opening up that area in the back of the Jeep, so you don't have that big can
to crush.
This is still going to exit over the axle at the rear of the vehicle, but that's where
one of the differences are.
This doesn't have a fancy polished tip on it like the Flowmaster does.
This is going to just be the regular 2.5-inch tubing bent down at the end with a bologne
cut on it.
Now, that tubing on this system is a 304 stainless, which is the higher grade stainless that you're
going to find in exhaust systems for your vehicle.
So, this is going to even more resistant to any sort of surface rust especially if you
live where we do up here in the rust belt.
A system like this is not going to rot away on you.
It's going to have the most resistance against any source of oxidation or corrosion.
So, if that's what you're looking for, this is going to be an excellent system for you.
This one just like that Flowmaster American Thunder is going to require a little bit of
cutting if you're installing this on a two-door, but pretty standard, pretty straightforward,
not a big deal for most of you guys to do on your own.
And of course, the muffler itself is going to be a flow-through design.
It's going to be a little bit more raspy, a little bit louder than that Flowmaster that
we had just talked about, maybe a little bit less refined.
Overall, I think this is a very well-built system.
It's a very simple system, but it's very high-quality materials.
The build quality is there.
In fact, there's really not much here that you can mess up from the build quality perspective.
You have a couple of welds on the actual pipe for the hangers itself, and then of course,
in the muffler, but there isn't a lot that you can really mess up with this system that's
as simple as this one is, and you're getting very high-quality materials all for about
$200 less than that Flowmaster system that we had just talked about.
So, if you're okay not having a polished tip, I think this is going to be an excellent choice
for those of you that are on a little bit of a budget, but still want a very high-quality
build material in your exhaust system.
This system is the Magnaflow Off-road Pro cat-back exhaust system, and this is the shortest
system that we're going to talk about today, and thereby, is going to be one of the loudest
systems that we're going to talk about.
Where the last two systems did eliminate that factory muffler, replacing that factory resonator
location with a bullet-style muffler, which this system does as well, those systems still
dump after the axle at the back of the Jeep.
This system is going to dump in front of the axle, so you have less pipe.
Less piping is going to have less of an opportunity to mellow out that sound, so you're definitely
going to get a louder, more raspy, more raw sound out of this system.
Now, the benefit to this system is that you have even less pipe underneath the Jeep to
bang and bend up when you're off-road.
So, if you're doing some really serious wheeling, and you really wanna have the least amount
of piping to get damage, this is going to be the way to do that.
So, the most sound, the lower, raspiest, most raw exhaust note through the least amount
of piping that you can bend, and still having a very high-quality well-built system from
a company like Magnaflow.
This is still stainless steel.
We're not stepping back into aluminized.
You are getting a lot of this system.
Now, because this is Magnaflow, because you're getting high-quality of build, high-quality
of materials, this is going to be more expensive than the pipe system that we talked about
even though it is less material, and a slightly lower grade stainless.
So, it really comes down to what you're looking for.
What's most important to you?
Is it sound?
Is it quality?
Is it how short the system is and how much that leads you to damage on the trail?
For my money, if I do a lot of wheeling, if I really want the most aggressive, loud, lowest
raspy exhaust note that I can find, this is going to be an excellent option.
So, those are my picks for cat-back exhaust systems fitting your '07 and up JK.
Today, we talked about the Magnaflow Performance Series dual-exit cat-back system, the Flowmaster
American Thunder system, the Pypes high-clearance system, and, finally, another Magnaflow system,
the Off-Road Pro system by Magnaflow.
Again, these are just my picks for four systems.
There are a lot of exhaust systems out there for your JK.
So make sure you comment below.
Let me know what you think about my picks, which system you're running on your Jeep and
