Just for reference, these were my results last time I smogged the car. Only put the cat and stock muffler on the car, no air injection and no smog pump hooked up.

15mph, HC (PPM) was 20 (max was 133 and Avg 41), CO% was 0.06 (Max was 0.82and Avg 0.13)

25mph, HC (PPM) was 24 (max was 108 and Avg 29), CO% was 0.04 (max was 0.62 and Avg 0.11)
