Anyone running the Ark 4-1 header?
Was wondering if anyone is running this header for their SC application and can provide any feedback. As far as reported gains/losses and overall impression. I just can't get the big daddy right now and this would be a great 4-1 alternative.
The design is VERY simliar to Comptech's...
Let me know!

No sorry, never heard of it. But I'm always interesting in looking for more ways to make power without adding boost. I'd like to know as well since I'm still running OEM.

Here's the link Junky, it's also in the official header thread. They first listed it around $950 but it's $800 on their site, so I may consider purchasing:

Cool thanks.
Its a tough decision for me to go with a header, oem is really quite good. I need some real data to know what I'm getting. I like the idea of the 4-1 design becuase of the added mid/upper gains they can provide, but not if there is a loss in the lower rpms. I'd like to know if there is any losses before I take the plunge.

How did it look Jaw Knee? Can you post it?
Junky, I totally hear you. I emailed ARK up and they claim there is a dyno post here on the forums, so I replied back asking to show me the link.

Out of curiosity, I know people say that the CT header was designed with SC in mind, but I didn't necessarily hear that in my correspondence with them.
Is it because of the 4-1 design lends itself more advantageous to the upper-end where centrifugal SC's shine?

Yeah, that's my understanding. Junky can break it on down, but the 4-2-1 shines in low to mid RPM's while the 4-1 is mid to upper RPM's, taking advantage of the SC. This is why the Hytech longtube SC version is dyno proven, and they designed it with a SC (but oh so expensive...).
