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.

With PEM'* and high flow cat..the rear O2 still reads fine.
Most find they don't need to sim it unless they are really going high performance.

Ok, must be my Sub is just touchy. I am looking at the highflow headers, cat, and making my own 3" dual exaust. (Dual after muffler, just for looks.)
