So I installed my SGT headers but had a heck of a time taking out the O2 sensors. The 2 post cat where a nightmare so I'm pretty sure I damaged at least one of them. After starting the car and idling it I got the SES, scanned for codes and got a P0140 (O2 Sensor circuit no activity detected (Bank 1 Sensor 2) and P0155 (O2 Sensor Heater Circuit (Bank 2 Sensor 1)......... so before I jump out and buy new just looking if anyone local has some used ones. I'm looking for 1 pre cat and one post cat on the long header.

Post cat Oxygen sensor Bank 1 Part #11781406621
Pre Cat Lambda probe Part #11787540167

This one I don't think I need this one but I'll just list it in case;
Post Cat Oxygen sensor Bank 2 Part #11781406622

By the way I'm testing some defoulers with a mini cat inside so I hope this works, it will allow you to run headers without moving the post cat sensors to section 1.

Thanks
