Here in NY older cars only go through a tail pipe test. The Justy has an air injector right after the cat (which is bolted onto the exhaust manifold). The replacement system has a modern three way cat that goes where the single stage cat is now (think resonator type placement). I have to loose the air injector for the replacement system.

 

Those who have removed the air injector, do you still pass(non CA) emissions?

I have seen it work that way on EA's - not specifically Justy's but I have seen people eliminate the AIS system with the installation of a new cat and pass smog without a problem. The new cat's don't need that system.

That is what I thought, thanks.

 

It is basically the same system as other 80's vehicals, just the justy has an oddball cat and i wasnt sure. All elose fails it is an OBD1 system and my mechanic has always been good at *ahem* guiding older vehicals through inspections
