CA Smog Test Levels Comparison
So I was smogged the other day and although I passed I was curious as to what others have gotten on their tests as I was under the impression I should have produced less emissions than I did.
15mph 25mph
HC: 32 20
CO .22 .39
NO 180 227
Mght about half of what is legally allowable and was trying to figure out why it wasn't lower. REVI intake with ram duct, Mazdamaniac ignition. Mazdaspeed catback, and stock cat. Denso iridium plugs have about 30k and probably due to be replaced but was all I could think of.
Are these numbers about right?

I know two guys in SoCal who recently smogged their cars, maybe I'll get them to post.
P.S. what the heck is a "mazdamaniac ignition"? Do you mean the BHR Ignition?

My results (original engine):
2010, 32K miles
2012, 62K miles
I was surprised about the huge jump in NO emissions (does that mean my cat is failing?), but the rest appears to be OK. Everything is still way below the passing grade.
2010, 32K miles
Code:
15 mph 25 mph HC 0 0 CO 0.06 0.07 NO 0 0 CO2 14.9 14.9 O2 0.1 0.0
2012, 62K miles
Code:
15 mph 25 mph HC 1 0 CO 0.01 0.15 NO 9 8 CO2 15.0 15.1 O2 0.0 0.0
