Seems there is confusion even among testers regarding the 2012 'Cat' emissions test.
The new regs apparently state that step one requires that on vehicles that qualify for a full cat emissions test, a visual check for the presence of the catalytic converter is first made.
If the cat is present visually, then a BET is done. The 2012 BET (Basic Emissions Test), as far as I can find out, is no different to the current BET.
Only if the vehicle then fails the BET is a full vehicle-specific emissions test carried out. So a BET pass means that no further cat test is carried out.
This brings in Simon's point - gut the cat but leave it in place and you will pass unless you fail the BET which is no different than today's test. Remove the cat, and you will definitely be in trouble.
Just my penn'orh.
