You'd think I can get somewhere with this as it's just the EPA Tailpipe Emissions Test... right? Wrong. Again... only references the SCCA rules.

Tell me this, how can one be sure they're in compliance with the rule, as written, if it can't even be found on the web? IMHO, if there is no result of EPA Tailpipe Emission Test when googling, can one simply say "it does not exist?".

Edit: PS, the rule didn't really change. They just took out "ST" from the original after I actually looked it up and finding out that 14.10.6 doesn't really exist (but 14.10.F.6 does).
You figured it out (not a new clarification), but if you want to see attempts at explaining what it means, here you go...

Cliff's notes: The EPA pretty much said there was no such thing.

For example, some states use tailpipe tests that measure percent or part-per-million, while others measure grams-per-mile. There is no federal, minimum cutpoints based upon test types, however.
I would say we are pretty much stuck with it.
