Huuum - I went for my NJ inspection yesterday (every 2 years) the State run stations now employ Parsons to do a full test similar to CA. The allowable Nox is about 800+ and the HC is 114. In 2002 (my previous test) with 100,000m, my Nox was around 160 and my HC was 9. This year with only 117,000m the Nox was over 600 and the HC just made it with 113. That's an incredible increase for only 17,000k (in 2 years). The only change on my car is new downpipes and "new" high-flow cats, about a year ago. Seems strange don't you think?
