Could anyone tell me where the 02 Sensor is located on the factory header? Is it up close to the manifold or low down near the flange that mounts to the cat? I would just go look for myself but it is VERY cold outside. I’m asking because I want to be certain that this header I’m looking to buy will fit my car and not the 94+ Teg’s… thanks guys!

if its a 90-91, then its up on the manifold, 92-93, down near the cat. a search would have yielded you answers as well.

I did a search but the O2 part was too small for a complete search.
Thank you for the info though… MUCH appreciated!
