Heated O2 sensors
Planning to install long tube headers with cats. While reading the current threads about similar installs, heated O2 sensors are sometimes mentioned as necessary for the headers. Why? :steering:

Re: Heated O2 sensors (vettfvr)
The O2 sensor must get enough heat from the exhaust flow to maintain 300deg C in order to operate.
Sometimes when headers are installed the O2 sensor is placed too far down stream for sufficient heating.
My experience with ceramic coated (inside/out) LT headers is that, with the O2 sensor(s) located in the collector there is sufficient heat for normal operation.

Re: Heated O2 sensors (65Z01)
I concur with last post. :iagree: My TPIS coated headers seem to keep my O2 sensor heated and I have set no codes in the two years of operation, although I too have wondered if I should go to the expensive 3 wire setup.

Re: Heated O2 sensors (corvette1990)
I appreciate the responses. I found an excellent tech tip on the issue as well. Still interested in others' opinions on TPIS headers or Exotic Muscle headers and the need for heated O2 sensors on a 96. :steering:
