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! --------------------  |

you can ditch the 2nd O2 sensor. Mines got the plug just hanging there without the sensor. Keep the plug so you can make a bridged connector should it throw an engine light (shouldnt though)
on some cars you need it there, with an extended bung to lift it out of the direct exhaust stream but not ours. get rid of it -------------------- Mike W
