California emission test

I'm hoping someone can help me with this problem. I took my car in for a
It's annual smog test and it failed for the first time ever.

Everything was OK up until NOx reading at 25mph, and that was only 3 above max allowable. The smog guy recommended I get a new catalytic converter and take the test again after the repair has been completed.

So my questions are:

1. Do I really need to spend 300 to have a new cat installed even though there was only a 3 point differential between my NOx reading and max allowable?

2. Would using high octain fuel with octane booster bring the number down to the "acceptable" range?

3. What else can I do to get that number into the acceptable standards. Keep in mind that I am money crunched and have to do the work myself. Cheaper is better. Free is best.

Thanks
 
Hi this is a bit out of are league for emmision's law's as the uk law's are once a year and the test is done stationery and the reading's are below Co 0.20 lambda 96-1.03 and HC below 200ppm for any car after 2001
