Supersprint V2 step headers question

[johanness]

I threw the following codes:

2C7E - Oxygen sensor after Cat trim control
2C93 - Exhaust gas temp sensor plausibility

So I go back to my shop, have them shorten the j-bungs (so that the end of the sensor is as close to stock as possible)and double/triple check all the wires run. Clear codes.

Drive home - nada.
Drive to get beer @ 6:52pm - CEL!!

I'm officially done with this until someone can point me in the right direction. If anyone has any further ideas, it would be greatly appreciated.

any updates, how is the car running with the V2 stepped headers?

still CEL free...
