i emaild vosa with the detail of my car n this is what i got back, "Good Afternoon, Thank you for your e-mail. All vehicles require an emissions test, if the tester finds an exact match for your vehicle on the analyser data base or inservice emissions book then he will carry out a cat test. If there is not an exact match then it will be a non cat test. If however the vehicle was built without a cat then you will need to provide a letter from the manufacturer in order for them to complete a non cat test. Having checked the In service Emissions book their is not an exact match for your vehicle so it would be a non cat test that would be carried out. Regards Christina" so deffinetly no cat needed!
