Hey guys, Stephanie here and today we're gonna be taking a look at the Kooks 1-7/8 inch long
tube headers for 2008 and newer 5.7, 6.1 and 6.4-liter owners out there.
So these long tubes will work for most but if you have the 6.2 you'll obviously be looking
elsewhere for headers.
These long tubes have 1-7/8 inch primary tubes which makes them on the larger side and it
means that they're really gonna open up exhaust flow.
These are gonna be ideal for someone who has some supporting modifications who's looking
for a top quality stainless steel long tube and that doesn't mind paying for these qualities.
This calls to right about $1,200, I'm gonna call the install a three out of three wrenches
in the difficulty meter.
Long tube headers are gonna be a big upgrade over the restrictive cast iron manifolds.
Long tubes will make for a very free-flowing exhaust system especially with an aftermarket
mid-pipe or cat-back and especially if you go with an off-road or catless setup.
You'll see horsepower and torque gains and also get a big improvement in sound from long
tubes.
Those gains will be slightly larger in the case that you go with an off-road setup and
you can expect more sound without cats too.
So we just said that long tube headers are gonna offer both performance and sound gains
but the end result of your headers will depend on the rest of your setup.
When I say end result I do mean both the performance and the sound gains.
And if you're looking for the best performance out of your long tubes you'll want to consider
having some supporting mods with these headers.
With that being said you don't necessarily need a tune in order to install these headers
but if you're looking for the most performance out of them, you'll want a tune to help with
that, so just keep that in mind.
Taking a look at the specifics here, these are a 304 stainless steel header that has
a natural or raw finish which is gonna be different than a chrome or ceramic coated
header.
Now obviously it doesn't have the polished appearance that a chrome header would have.
While these don't have the ceramic coating either they are made from that 304 stainless
steel tubing, so you won't have to worry about corrosion.
Not to mention you get to see the beautiful welds here since these do have the raw finish.
Over time the stainless steel headers will color slightly as they're heat-soaked.
But overall the appearance will hold up.
The primary tubes have that larger 1-7/8 inch diameter like I mentioned earlier.
They are mandrel-bent to help with smooth airflow and they merge down to a three-inch
collector with a scavenging spike.
Kooks always uses scavenging spikes just to make sure the headers will flow perfectly.
And Kooks uses a ball and socket design here for a tight and leak-free fit.
That leads me to the connection pipes.
You'll need to run Kooks connection pipes with these headers.
The connection pipes are three-inch and you can pick them up catted or uncatted.
The headers will come with an extra O2 bung for a wideband O2 sensor.
You also get two O2 extensions, gaskets, stage eight locking header and collector bolts and
all of the install hardware.
Touching on the install again, this one is gonna be a three out of three wrenches in
the difficulty meter.
Long tube headers are a difficult install.
With that being said that's gonna wrap up this video.
