I do not have anymore readings from the inspection, everything was posted on first post. Yes, only the ASM2525 and the curb idle test, plus the gas cap pressure test are conducted. Apparently the limits were lowered in 2005.

The car was runnning for about 45 min. with a 15 min. highway run at 100 KPH but then it sat in for 50 min. in -5c temperature. The testor was 30 min. late. I actually went out and started the car about 5 min. before the test and got the coolant temp. backup to about 85c as the guy came out to get the car.

When you say catalyst, is that the catalytic converter? and is that the part of the exhaust system, connected to the crossover pipe, where the o2 sensor is?

The HC ppm reading is double the limit. How can I get the cat. hotter and what is the probability that it will be cut in half just becuase of heat, to less than 50 from 101?

I do have a brand new complete exhaust system from timevalve, hanging on the garage wall. The existing exhaust is still in decent shape.

Should I just replace the exhaust system? Should I go for a diagnostic to determine the reason for not meeting the emission standards? If I go for a diag., should I go to the dealer or any certified repair tech. shop, like the one that did the test?

The emission report does state a repair cost limit of $450. I can get a conditional pass, if I spend at least $450 on emission related repairs (including parts, labour , diagnostics). The car cannot be sold with a conditional pass but I can get the plates renewed.
