In my copy of IVA manual dated 27/03/2009 Page 8 of 13 in section Metered emissions 02B
The flow chart shows:
CAT1
is it a passenger car? = yes
vehicle effective date between 1/8/92 & 31/7/95? = yes
can you find an exact match in the analyser data base or the In-service Emissions book? = NO - because the haynes roadster isn't in the book!
Carry out a NON CAT test CO<=3.5% HC<= 1200ppm
I would call that a non cat test for any haynes roadster with an engine that was pre'95 so long as engine age could be proved - which should be no problem - just contact the engine manufacturer and they should be able to provide a letter confirming date.

PS this is exactly the same flow chart as the one in my old SVA manual.
