  1. O2 Sensors on Mustang SVT Mk IV Base Build

    Factory Five Roadsters
    I am using a 2001 Mustang Cobra SVT donor for my Mk IV build. I'm using the Mustang wiring harnesses and will keep what I must for the emission controls. Do I need to include both the front O2 sensors and rear cat O2 sensors (obviously including the catalytic converters as well)?
