I wonder if anyone has any advice for me. My car is a 2001 Boxster S. When installing the Schnell Headers I bought from Vertex I had to remove/loose the front catalytic converter. It is part of the factory manifold so when you remove the manifold you also loose the front catalyst. I sucessfully relocated the existing O2 sensors to be infront and behind the rear catalyst.

After 200 miles my CEL has came on and it is because of the O2 sensors.

What are the rest of you doing to overcome this situation? As I am most likely not the first person to install headers I can not be the only person with this situation.

Thanks

It is my understanding that the first set tell the ECU how to provide correct fuel. The second set tells the computer how the CATs are working. There is a device you can attach to the unused O2 sensors that provide a reading acceptable to the computer to prevent the CEL.

The other option is to put an o2 sensor bung just after the second set of cats and lengthen the 02 sensor wires to reach.
