Hey 6gc,

I'm looking to order new o2 sensors but I have a question. Stock, the st205 has two oxygen sensors; both on the downpipe, one before and one after the integrated catalytic converter. I just purchased a berk downpipe that only has a spot for one sensor. My questions are:

1. Do I need both o2 sensors?

2. Can I replace one of the sensors with an AEM uego wideband? Or will a non-oem sensor throw cause the ecu to throw codes?

Help is appreciated!
