The following was found on a web page listing the dates and limits for testing.
  1. First used between 1/8/75 and 31/7/86 - meter test CO <=4.5%, HC<=1200ppm.
  2. First used between 1/8/86 and 31/7/92 - meter test CO<=3.5%, HC<=1200ppm.
  3. first used between 1/8/92 and 31/7/94 - advanced emission test (CAT) if its running on petrol when presented, to the vehicle specific limits usually around CO<=0.3%, HC<=200ppm and Lambda 0.97 - 1.03
My Griff from the V5 is listed as date of first registration 28/08/92.
Does this make it subject to the advanced (cat) test even though it has? never had any cats fitted?????

I think you will find there were many TVR's actually built before the cut off date and they don't have cats.

Yours should be OK..
