Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause
The factory manifolds have proven to be the best option.
Leading evidence: 'best option' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'best option' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Run these' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Wow, specs and price look incredible...If no one is running these, maybe you could be the guinea pig??!!
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

They are just cheap Chinese headers that will gain you nothing. The factory manifolds have proven to be the best option. If you want to "upgrade", look into 997 factory manifolds.
If your existing headers are broken somehow and new ones are needed on the cheap, this could be a great option! But as a performance upgrade, it doesn't make sense. An unsubstantiated claim if 10-15 hp/torque increase. Even if they had data to prove it, that's only a 3-5% increase, and probably only at a particular RPM range; not enough to feel in the seat of the pants.
Your go-fast money would be better spent on titanium lug bolts
My motor came with some cheap no name headers and one of the flanges warped. So I'm debating buying another cheap set or pulling the stock manifolds off of the broken motor. But the old motor is in storage and buried behind a bunch of stuff, I thought these might suffice.
Hey Bill,
Where did you find your motor? Any tips from your experience would be great to know. It might be covered on your longer thread but I am debating swapping the motor.
Bill
These headers are missing key components to a quality built header.
1) 1.5" primary tubes, you should be looking for 1 5/8" for a 3.6
2) Primary tubes are not equal length
3) Primary tubes are pieced together with a seem weld.
4) Collector design doesn't allow the three primary tubes a smooth transition for exhaust gas to flow.
Google search, as op stated does confirm china mfg, as most of the headers are.
Even fancy brand name companies source generic headers and put thier names on them. There are some good threads on headers here
This is a source reference. Confirm exact model applicability in the original material.
