Hello, I have a 91 with an aftermarket header. I bought the car as is, but it's throwing a cel for oxygen sensor. The header doesn't have anywhere for the o2 sensor to go, and I'm not sure what to do. Any suggestions?

 

My problem seems to be similar to this http://hondaswap.com/general-tech-ma...-header-70535/

 

1. Test pipe w/ a O2 bung.
2. Header made for 90-91 DA Integra
3. Header with O2 Bung in collector, and just extend your 1 wire O2 Sensor
4. Go back to OEM Manifold.
