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.

2018 Jeep Grand Cherokee Trackhawk First Drive Review - Duration: 7:44.

We're invited is to say that the 2018 Jeep Grand Cherokee Trackhawk is laughable.

It's borderline frightening to think that we are today live in a world-wide where anybody

with the money and the gumption can stroll into the nearest Jeep dealership and home

an order for a 707 -horsepower Hemi-powered Grand Cherokee.

Let's threw this slice of record into position.

The original Jeep, the one used by the military, boasted 60 horsepower from the Go Devil four-cylinder

engine for the purposes of the hood.

The most powerful version of the muscle car-era 426 -cubic-inch Hemi was factory-rated at

425 hp.

And even if that legendary powerplant was underrated from the factory, the Grand Cherokee

Trackhawk still eliminates it by a couple hundred mares .

In an SUV.

Seven-hundred-horsepower sport utility vehicle doesn't precisely roll off the tongue, does

it?

And conventional wisdom says it shouldn't.

But we're here is to say otherwise.

After driving the Trackhawk in and around the streets of Portland, Maine, and taking

it to Club Motorsports in New Hampshire, we're remain convinced that Jeep and SRT engineers

have managed to defy physics and ground.

The Trackhawk isn't just tight, it's also manageable.

Subdued, even- at the least when you want it to be .

Put the mallet down, summon the nearly demonic superpower of supercharged combustion, and

all inferno infringes loose.

But the tires don't.

With launch dominate engaged and with the programmable machine rapidity properly preferred,

the all-wheel-drive Trackhawk rockets to 60 miles per hour in just 3.5 seconds, over and

over and over again.

No drama , no wheelspin, just g-force, pressing you and four close friends into the backs

of your sits.

It's addictive, and the only sanction is single-digit fuel mileage.

But we'll gambling a guess that anyone store for a Trackhawk isn't much worried about its

boozing question .

The only proper way to experience the Trackhawk's acceleration is from inside.

But, to give you an idea of its rapidity and superpower, check out the videos below.

Stick around for a walkaround both inside and out, and for a look for the purposes of

the hood .

Jeep had to make a few small changes to the well-known 6.2 -liter supercharged Hellcat

V8 machine to shoehorn it for the purposes of the hood of a Grand Cherokee.

The oil pan is reshaped and amazed, the intercooler is modified, and the exhaust gases manifolds

are new.

The develop is a reduction in torque from 650 pound-feet in Dodge Hellcat models to

645 in the Jeep, but we wouldn't worry about that.

Continue your paw planted for 11.6 seconds and you'll have crossed the quarter-mile doorstep.

We reached 120 miles per hour on the long straight at Club Motorsports, but if we'd

have had a longer runway, we have zero mistrust that the Trackhawk would make its claimed

180 -mph top speed .

We feel been obliged to be borne in mind, again, that the Trackhawk is an SUV , not

a sports car.

Good happening, then, that the six-piston Brembo calipers and 15.75 -inch rotors at

the front and four-piston calipers with 13.78 -inch rotors at the backside are the largest

ever fitted to a Jeep.

Mash those brakes and the 5,363 -pound Trackhawk will come to a stop from 60 in just 114 feet

.

It likely goes without saying, but we'll say it anyway.

None is going to take the Trackhawk off-road.

Jeep knows this and removed unnecessary situations like a low-range transportation case and dirt

or boulder modes from the Selec-Track terrain management system.

That leaves Auto, Sport, Track, Snow and Tow modes make their own choices .

The Grand Cherokee's Quadra-Trac on-demand four-wheel drive method is beefed up to handle

the hellacious superpower of the supercharged machine with new drive rods, a stronger rear

axle, forged sword chain sprockets and a stronger differential house.

An eight-speed automatic transmission is no other gearbox available .

We have no qualms with the powertrain, or Jeep's claim that the Grand Cherokee Trackhawk

is the most powerful and quickest SUV ever became.

But we do please the steering ratio was quicker than 16.5: 1.

Too often we noted ourselves envisaging at the rotation to keep the Trackhawk under control.

A variable-ratio component are certainly assistant.

Formerly it's moment in the proper direction, Jeep's skill in programming all-wheel-drive

organisations sheens.

There's not much drama in how the Trackhawk treats the twisties, despite the huge glob

under its hood.

Grippy P295/ 45 ZR20 tires help, but the overall sense of plantedness and the absence of body

roll initially comes as a astound .

Jeep fitted the Trackhawk with a steering wheel that's nice and meaty at every site

your hands wishes to grab.

Paddle shifters on the back of the rotation work well, but the transmission's alteration

logic is good enough that we predominantly didn't bother with them.

The sits in the Trackhawk are comfy, but proprietors who plan to use their Jeeps at the racetrack

will probably wish for more aggressive bolstering .

There aren't a lot of obvious exterior changes to separate the Trackhawk from the regular-grade

Grand Cherokee SRT.

Badging is different, of course, and so are the exhaust tips at the backside.

Up front is a new fascia became most noticeable by the loss of its haze lamps, which are replaced

with breath intakes to help keep situations refrigerate for the purposes of the hood .

Jeep declined the go height of the Trackhawk by an inch, and we suppose the SUV appears

best with the optional flat-black forged 20 -inch rotations fitted with Pirelli P-Zero

three-season tires.

A backup define of rotations with proper wintertime tires are likely an absolute necessity in

snowy climates.

We doubt numerous proprietors will be towing ultra heavy consignments with the Trackhawk,

but its 7,200 -pound max rating surely allows for trailers, spray skis or dirt bikes .

With a starting rate of $86,995, the 2018 Jeep Grand Cherokee Trackhawk isn't cheap.

But it's less expensive, quicker and most powerful than the BMW X5M or Porsche Cayenne

Turbo S. It's also $2,000 dearer than the 840 -horsepower Dodge Demon.

But the Demon is a one-trick pony, and the Trackhawk is most definitely not.

In happening, Jeep's latest super-powerful utility vehicle may be the perfect automobile

for anyone who desires practical execution .

We is entered into our first stint in the Trackhawk thinking it was ridiculous.

And "its by", but not for the reason we had speculated.

What's really crazy is how well the thing wields .
