Another option for cheap headers
 

Not really in the market myself, but for $127.99 a set, including all hardware and gaskets, with free shipping, these seem tempting. Maybe they're just as cheap on eBay, I don't know. Just happened to see these on Amazon and thought I'd pass along the link in case someone here wants to be the guinea pig.

Amazon Boxster headers

These are the same ones I just installed. Their fit is pretty good, but the sensor bungs on the passenger side will need 90 degree adapters to fit the o2 sensor - there isn't enough clearance between the block and the bung to use the first hole and the sensor will extend about 1.5cm below the rest of everything under the car byo mounting it to the second bung. Not a deal breaker but just FYI. The welds look halfway decent, the head plate was very flat, and fitment against the block was pretty good and there were no alignment issues. I fabbed up straight pipe from there though, so I have no idea if they will mount to factory midpipes well although the flange is at least oriented properly (which is a difference between our headers and the 987 just in case you start looking at those lol)

I had cheap ebay headers on my Boxster for 7 years without a problem including many track events. Big word of caution though, the exhaust manifold bolts on Boxster's tend to snap off in the head which can be a HUGE problem. I had to tow my car to a machine shop after every bolt extraction method out there failed.
