Exhaust Mainfold Sensor port
On long-tube headers (Pacesetter, LCE, or Thorley), I'm not seeing a port for the sensor where the the sensor normally is on the stock manifold. When putting on a long tube header, does that sensor need to be rerouted? Those systems come with a sensor port down by the cat, which is a different sensor, altogether, I believe. Stock exhaust has two sensors. Aftermarket long tube headers only have one. Am I missing something?
Thanks

I just got home and looked at the stock manifold, there is no sensor hole like I thought, just the flat in the cast, so I think I only have one sensor, presumably O2, which is down by the cat. Thanks

I believe the downstream sensor is limited to California vehicles. But it does support code 27, which helps monitor the cat, so if it showed up in a non-California vehicle that would be a good thing.
