Question, did you have to use o2 sims to keep the check eng. light off? With my Suburban I had to put them on when I replaces my stock exaust manifolds with high flow headers and cats.

He'* OBD-1 so he'* only got the front O2 sensor. Correct me if I'm wrong but I think OBD-2 Bonnevilles need a rear O2 sim to prevent a code when they switch to a magnaflow cat. You can get the DTC disabled with an aftermarket PCM too.
