I know some hfc do not throw CEL, but does that mean that it will pass a NYS inspection?

as stated below if you have a tune that disables rear o2 readiness the car will not pass but if you don’t and the cats work as advertised then you have a chance at passing but it’s a longshot. You may be better off with o2 spacers if the heated catalyst does not go “READY”
