The
four-inch pipe system that we have here will be an awesome choice for the EcoBoost owners
looking for a super affordable larger diameter system that will deliver a little bit more
volume, but more importantly, a full stainless steel build for south of 500 bucks.
Now, this particular system does feature the black tip, as you guys can see, in addition
to that single side exit configuration.
The install, it's gonna involve a little bit of cutting depending on your cab and bed size.
But I'm still gonna go one out of three wrenches on the difficulty meter as it shouldn't be
that difficult, and we will have some more on that later in the video.
So the four-inch systems are a bit of a rarity in the category but will certainly have their
appeal.
Now, by going with a larger diameter system like this, it's gonna be a great choice for
those truck owners out there who might be a little bit more interested in adding performance
as larger diameter piping traditionally reduces restrictions on a turbo application from the
turbo back.
This is going to be a great complementary mod to those other aftermarket power adders
such as your tuners, for instance, your downpipes, intakes, things like that.
Well, let's get into the sound with the Pypes four-inch system here because that's what
we're all here for after all of course.
And honestly, this is a very tame system.
I was a bit surprised.
You'd think larger diameter piping, aggressive violator muffler straight through by design,
you'd think you'd be getting a lot more volume out of something like this.
But that really wasn't our experience.
Instead, breaking out my wake the neighbor scale, I'm gonna go pretty tame three out
of five here with the pipe system.
Listen guys, it's not a bad thing.
I actually really enjoyed the tone from the pipes, deep tone overall, very smooth, certainly
not obnoxious on the six-cylinder truck, and it's something I think a lot of EcoBoost owners
will enjoy.
A little bit of noise inside the truck while cruising but definitely not a deal-breaker.
So how did Pypes achieve this with their four-inch cat-back?
Well, the big story here of course is that violator muffler as we just pointed out.
And this thing is gonna feature a combination of this internal louvered sound tube working
with some mini sound deflectors, which is basically gonna be responsible for shaping
that deep kind of mild tone overall.
But sound aside, I think the big draw with the pipe system is gonna be that larger diameter
four-inch tubing, all of it mandrel bent and everything made from 409 grade stainless steel.
Now, it's all gonna exit out of this massive five-inch black tip, it has been powder-coated,
and it will dump in the factory location right behind your passenger side rear tire.
Quick heads-up Pypes does also offer this exact same system but with a standard polished
tip.
You can find that on the site as well, actually cost you a little bit less than the black
tip we have here.
And like I said earlier in the video, guys, this is a very affordable cat-back.
In fact, at the time of this video, it's the most affordable four-inch full stainless system
that we offer.
Yes MBRP and Heartthrob will offer their version of a four-inch system, but both of those are
made from aluminized steel and not 409 grade stainless like the pipe system here.
What does that mean to you?
Well, aluminized steel traditionally isn't as good at reducing corrosion like stainless
steel.
So if you live in a snowy or salty climate, you might see some surface corrosion on those
aluminized systems over a few years, whereas the 409 will certainly give you a little bit
more durability.
But let's switch gears and quickly talk about the installation.
And for the most part, guys, very basic stuff.
However, some of you might encounter some cutting depending on your cab size and also
your bed size.
Even with that being the case, I'm still gonna go one out of three wrenches on the difficulty
meter and about an hour or two from start to finish depending on how fast you like to
work.
Tool wise, basic socket set, cordless impact or air tools will definitely speed things
up.
And don't forget your Sawzall or cutting tool along with your eye protection if you do need
to trim the system.
Other than that, just the basic lift, jack and jack stands, race ramps to help you get
the truck in the air slightly, and finally, a little spray lube to help you with some
rusty bolts in addition to those rubber exhaust hangers.
Remove your factory system first by loosening the clamp closest to the resonator.
At this point you can drop the factory system off the hangers and carefully set it aside.
With that out of the way, get your trimming knocked out.
After that, hang the pipe system from front to back, snugging up your clamps as you go,
but be sure to save that final tighten up to the very end to give you some play with
the system.
Once you have everything where you want it, go ahead and torque down your clamps, and
your installation is complete.
So, if you're looking for a four-inch stainless steel system for south of 500 bucks, the pipe's
going to be your best bet.
