    okay i did a search but came up short. i'm getting ready to fab my dual exhaust system. it will be flow tech headers with 2.25" or 2.50" tube and balance tube. i want to install the 02 sensor in the balance tube. need to now what sensor p/n to use? and how to wire it? since the orginal o2 sensor is only one wire and is not heated. please someone point me in the right direction. this is going in my 89 k5 tbi

    go to the cfm tech website...... there is a writeup on this exact conversion...

    i found my idle happens quicker so the heated o2 sensor must be doing something different than the 1 wire....... but i dont think there is a super gas savings like they hope for
