Dumb question - but I haven't looekd at my teg yet under there at the cat but isn't tehre an )2 sensor in the exhaust manifold at the collector?
I have a '96 GSR or is there jsut the one in the car with it being OBD II?

Just curious. Cuz I am getting a header soon and soem pics I see of carious brnads have an O2 sneor bung at hte colelctor and some don't and I know hte pic may be a different model but jsut wondering.

Thanks
