Okay, when i ordered the header i specifically asked if the header would have a hole to put my o2 sensor and ofcourse the guy said yes, finally got my header and guess what, theres no freaking hole for the o2 sensor. On the box there is a picture of the header with a hole for the sensor and the instructions for it states "after installing the header, install the o2 sensor on your new DC header".
Anyway i called the guy(performancecenter.com) and doesn't know why i got the one without the sensor. so he told me to call AEM/DC headquarers and the person that i talked to said i got the right header all i need to do is leave the stock short pipe where my o2 sensor is on then connect my new header from there coz the DC header accomodates the stock piping and everything shoul fit and wor-out just right.
What do you guys think? Does that make sense?
Tomorrow im going to check under my car if thats gonna work.
