Spun Cats Question
Will the Spun Metallic cats work with the ECM or are they going to throw codes? I need all 4 O2 sensors, but can't fit factory cats in my system. Along these same lines, what is the best way to space the O2 sensor bungs? Ive got vette manifolds with the front O2 bungs built in. Any guidance on spacing the back sensors?
