Instant-G Boxster Headers

[LuisR]

then how about this kit from Fabspeed: http://www.fabspeed.com/Boxster.html
I have heard that they get their stuff done in China (which is not necessary a bad thing but you wonder how good the quality of welding and materials they use over there). The headers that I would consider getting are the Dansk but they don't have the O2 sensor receptacles for the usa boxsters and i don't want to have any lights go off on my dashboard. Are there any other good set of headers with o2 sensor compatible??
