      thats because you have a bigger window for the test due to your car being pre 1992. when cats were not compulsary

          Do you have to meet the same emmissions requirement? I guess yours must be tighter than ours here in the UK?

              Im sure I wrote up the emissions rules for the UK somewhere. Basically if your car is PRE August 92 then it needs no cats. If its August 92 on, then it needs to pass the MoT BET test. (This is only a rough guide). If the car doesn't pass the automated test procedure with the built in limits for exhaust gas, then the car fails.

              Its up to the MoT centre if they break the law and pass cars that shouldn't, so if your decatted 92 on car passes emissions, then it was fixed! Will put the exact wording on here later
