for anyone concerning the OBX header on ebay if itll fit or not. well i installed mine friday and its been great so far haven't thrown any codes and i can definetly feel an increase in power especially low end but other than that can't beat a header for only $230.

You haven't thrown any codes? That's suprising to hear. A guy on b15 has the OBX as well which is supposedly a straight up copy of the Hotshot and he throws a code just like I am with my hotshot. It says that you have an 03 gxe so that means you only have one o2 sensor as well. Which o2 bung did you choose to plug your o2 sensor into? Did you weld shut the other o2 bung and EGR bung or did you just plug them? Or did you just weld your own o2 bung somewhere lower down the header to relocate the sensor? I didn't throw a code at first either but after about 50 miles mine came on and hasn't gone away but it's understandable since the o2 sensor is reading wrong. How many miles have you driven with your OBX header on?

ok i welded the egr valve and the o2 bung that was on the same pipe i put the other 02 on the 1st pipe and on the mid pipe i welded the bung right next to the hanger so its far enough away for any heat problems i also think it has to do with the fact i had to replace the second o2 because i managed to stripp the origanal but who knows ive been 400 miles now and no code thrown...
