..."I'm also well aware that it is entirely possibly to pass OBD2 emissions sniff test (tail pipe emissions), again, like I mentioned before, without a catalytic converter installed.
I'm also very aware of NYS emissions inspection procedure, since the shop I use (who wishes to remain nameless for various reasons) is a legal NYS inspection station and performs my tailpipe emissions testing. "....
==========================
i am a licensed NYS inspector and have been since
before the feet steps caps fist edge testing and have the
saep certificate from NYS DMV to prove it .
what you describe above is INcorrect - and outside of current protocol
there is no tailpipe "sniff test" for an OBD2 car in NYS
and
an OBD2 car will code for cat efficiency if the system has been tampered with by removing the cat
so even assuming the inspector was fooled by the visual , the car would fail the test anyway .
as all OBD2 monitors must have run and passed and (post 1998)
2 un run IM monitors are allowed 1998 back to 1996
MR CEL must be functional and OFF when the engine is running
outside of the 5 counties of NYMA there is no dyno "sniff test" requirement for pre OBD2 cars .
