i recently installed a set of headers on my rs but they don't have a spot for the oxygen sensor so now i have a check engine light that always comes on. how can i reinstall the oxygen sensor or get the service engine light to stop coming. Any help would be greatly appreciated.

 

With out that O2 sensor haven't you lost more power then you might have gained with the headers. I would hate to see your gas mileage also. A lot of people sell kits to install O2 sensors in headers(a lot come with a fuel ratio meter also). Find someone with a good welder and a good drill press and they can set you up real quick. If you are going through the entire trouble, you might aswell install a heated O2 sensor instead of the less acurate stock ones.
