well, megan racing responded to me. an obviously-non-native english speaker (i could hear an accent in the email! haha) replied telling me that i needed to reset the ecu (i did that from the very beginning) or else i needed to "get new computer." that seems completely ridiculous to me, so i responded back asking just what was meant by that.
i am local to megan racing and i offered my car should they need one for testing. interestingly, the e-mail i got from megan sounded like they pretty much are going to keep making the header as is and they don't care about the CEL.
i also asked (politely) just what the purpose of the pre-cat would be if the header still causes the CEL. i mean, if all headers throw a CEL, then the obvious header to buy would be the one making the most power. the precat is a restriction in the air flow, so megan's header will naturally be a little less powerful than an unobstructed one like dc. i wanted megan's because it's pretty, a good price, and is (likely) CARB legal. my car won't pass smog when it's throwing a CEL, even if the header is CARB certified and has the pre-cat.
anyway, i plan to try the anti-fouler fix on friday. and if tctunerz finds a solution which isn't so hokey, i might even buy it (since i didn't buy the header from them, i guess i don't qualify for the free solution... heck, if the s-pipe solution is also a tasty upgrade for exhausts which don't include the s-pipe, it'd be a worthy addition regardless of the header/CEL issue -- hint, hint, quick!).

Are you selling a header & new s-pipe for $259? if you are, I will purchase one.
If you are unable to answer this question in a professional manner... Lets just say it starts with "no" and ends with "business"

Guys just because a header makes you throw a Cel it doesn't mean it's bad or a flawed design...yes it's annoying but it happens.
You have removed a Cat and now your EGT probe (exhaust temp gauge) is reading weird results that it does not expect.
I suspect that the Cel could be solved very easily and cheaply. i have not replaced my headers (yet) and I have not unplugged my EGT probe, but I am guessing that they are similar to many other cars. When I had my WRX, there were two Cel's that most folks worried about. One was when we gutted the uppipe's cat or simply replaced it. That dealt with the EGT sensor. the other was when we replaced the downpipe or the 3rd cat (yes, they have 3 we have two thank God) That one dealt with the O2 sensor. There are many fixes for these, most of which require a simple resistor to fool the sensors. There's a company that sells them called Pony Express. http://www.ponyexpressperformance.com/products.html
They make fixes for lots of cars...I bet one of those would work and if not they could easily make one. Note that these are for O2 sensors and so are more for when replacing the second cat (doing a full catless exhaust)
There are also cheap and homemade fixes that folks have done. here's one for the EGT sensor on a WRX...maybe one of you could go out and try it once you've replaced your headers? It's cheap!

I agree suby2scion, it's not a huge deal, but I'd like to know what I'm purchasing. if I receive a header & a new s-pipe for this much it's a great deal.
If they don't replace the s-pipe, I can try the spark plug anti-fouler trick.

RacerZack those are some nice picks you got there. I'm still thinking about makeing this my next engin mod. Though I'm going to wait a bit and see if it's a s-pipe fix or some one comes out with a header that doesn't throw the CEL or there are more test with this one. My main concern that every thing stays legal (atleast past emisions) while adding to the performance.
