It's a clean machine! (or is it?) 3.6 smog check.
 
Below are a pretest on my 3.6 SC without catalytic converters then a second test a week later after I added a pair of random technology catalytic converters. Can they really make that big a difference? I thought they were mainly for nitric oxide emissions, but look at the rest! What do you think?

Should have put that 3.6 in a pre-'74. Then no smog worries. :D

Smog is done. I'm good for two years. (Don't ask.) ;)

I did my SC yesterday. The car is stock so I only needed to reconnect the O2 sensor & lean the mixture out by 1/8 turn. It passed easily (though not quite as clean as the CAT-equiped 3.6). Now I can throw on the euro premuffler & dual out flowmaster- whoo hooo. Although the test only center I took it to didn't even pretend to look under the car for a visual on the CAT.
