2002 Aero Stage 2 w/modified exhaust cat back. I have seen several threads with this discussion but not sure of the conclusion. What has worked to eliminate the P0420 codes. Mine does seem to happen after extended same speed highway cruising. I have had the car a short time and I am not familiar with the prior frequency of the occurence.
Thanks for the help
