I would try those out, they look like a good design.

The stock headers are good, but aftermarket headers do help. They might not make a noticable amount of power, but what you do notice is your power curve starting lower in the RPM band. Regardless, if you are going to upgrade power in the future its going to be time to change them sooner or later.

at all, and actually hurt (max power and power under the curve) cars without
significantly bigger-flowing motors than stock. And these are guys trying to
earn my money by maximizing my power-under-the curve.

Then why do some of these tuners like EVO, Fabspeed Agency Power ect. (who we can consider top notch on here) even bother to produce and sell a K24 header?
When you say bigger flowing engines do you mean exhaust, intake tubing, Y pipe and mods like that, or bigger turbos?

So you dont think you they can tune thier clients cars to make more power with the headers then with out them? If you want to compare apples to apples, I am sure there is a benefit somewhere.
Well, from what I hear from the best tuners around, headers *don't* help

I don't have knowledge of that particular brand but my general feeling is that a lot of people change headers and actually hurt themselves in the end. If you're not running forced induction, then you're always going to sacrifice low end power with higher flowing headers. You have to add at least 25% more power to a naturally aspirated motor before I'd change the headers (yes I know I'm generalizing but that is true for most cars built in the last 10-15 years). I'd say the same thing for most factory high-output forced-induction cars as well. You really need to add significant HP before changing factory headers (or intakes) is really going to help you.
But what do I know, I've only been customizing my cars for 20 years.

So that goes for the GT2 as well, same headers. The headers are an important
part of a turbo car's performance, and getting them short and keeping the heat
in (Porsche's headers are double-walled), keeps the energy in the exhaust gases
and to the turbos. The idea the Porsche is somehow going to leave significant HP
on the table in their flagship cars is silly. Scott is right in saying that most folks hurt
themselves changing headers. If I recall the expert consensus in this and other 996tt
forums is that the ideal set-up is the stock headers, ported to better match the
exhaust manifold, and perhaps ceramic coated to keep some more heat in. This is
good for modded cars up to 600hp or so. After that, you may want to consider
headers, and what diameter tubing you want. The advertised headers above don't
even report their tube diameter, let alone quoting power figures, and their marketing
hype says they are the best bang for the buck, which is laughable. My vote for the
best bang for the buck has to be the Upsolute k16 flash I got for $300 or so and
got 1-bar and lots more real power I raced and won with with no problems for 7
years till I recently went to the fancier custom work of UMW.
