I'll see if our metallurgists can confirm the material through non-destructive testing.

Stazi,
The easiest (relatively speaking ) way to tell is to cut him a small piece off one of the lips on the pipes, say just a few mm square, away from one of the welds. Probably at the end of one of the header down-pipes. Then if you have the facilities you can use an SEM or FESEM to determine the composition by percent through x-ray detection. Even cheap SEMs have a way to read the x-rays. Your technician should be able to get a few SEM shots of the grains and grain boundaries too so that you can get a good idea of the metal by comparison.
Oh, there is EDS and EELS too but those are much more time consuming (read: costly).

We have an SEM with x-ray diffraction capabilities.

Tom you are comparing uncoated mild to uncoated SS.
I was comparing the Jet-hot style coated mild to uncoated SS. Exactly like the come.
Jet-hot coating a set of headers is in the $200-300 range IIRC. That makes the price difference very minor.
Also the W-R headers don't match the primary lengths nor does the overall build quality look very good. (Even if the material itself is better now)
If you want to compare just the price of the headers as they come it looks like the W-R headers have a huge price advantage. However when you look at the whole picture it's not such an advantage really and that's just from a price stand point. The MSDS headers have ever other advantage except the Y-pipe design. Then again I bet the W-R Y-pipe's extra length unbalances the U bend's pulse. Par for the course with Weapons-Rice. If you aren't going to exactly match stock then just remove it and tune your chip for it or run a modified stock Y-pipe.

WTH??? Greg, did you even look at the pics?? The primaries are IDENTICAL on both headers. Granted the y-pipe at the back has a longer section for the rear header, but I would think that it would be BETTER seeing as it's length is closer matched to that of the front pipe, i.e. what you would want ( qual length secondaries)
I don't understand why your fighting this so hard.
The only downside I can agree with you upon is the lack of couting, but my ADC headers aren't coated either and I have had NO issues with those, and they run way hotter than any N/A application herein.

Jet Hot coating a set of headers for the Duratec is $195 FWIW. $125 with a group discount but mentioned in the MSDS GB thread.

Wow ... Stazi headers would probably be a peice of cake to install when the trans is pulled right ...

Note: 304 and 304L are both slightly magnetic, which can be relieved after heating, so once they been run on a car above 700�°C they'll lose magnetism. The 304L is lower carbon 0.03% vs 0.15% for regular 304. The lower carbon in the 304L is better for welding (due to a lower precipitation of carbides). 304L is softer (Brinell 140) than 304 (Brinell 150) by a smidge and also has a lower tensile stregth of 80ksi vs 85ksi.
