I was originally worried by this...


"A catalytic convertor fitted as original equipment but missing will be a reason for failure."

Is this then wrong?

Hi Rawky,and welcome

If the vehicle is petrol driven then going by the year stated you will be ok in removing the cat,as although it has a cat fitted,it does not qualify for a cat emissions test to be carried out due to its year of manufacture.

If the vehicle was produced and petrol driven before 1992 the chances are they would not have a converter fitted as there was no legal reqiurement to have what is known as "ADVANCED EMISSION CONTROL EQUIPMENT"(catalytic converters).
There was a transition period between 1992 to 1995 with regards to the above systems and cats where fitted to all petrol driven vehicles.

A tester will know where a cat converter is fitted as original in my opinion anyway through his knowledge and experiance and no we have no database to give us this infomation yet,however we can refer to emission testing flow charts in the inspection manual.

As long as we talking about a standard production  petrol driven car here;then remove the cat and fit a de-cat pipe,however your vehicle will still have to meet limits to a non cat emissions test:)

Hi There,

I have a 1991 car with a faulty/blocked catalytic converter. I was planning to replace this with a decat pipe which is commonly available, but with the new 2012 MOT rules I am now in a state of confusion...

It used to be that a CAT wasn't a requirement if the car was first used before August 1992. Is this still the case or not?

How does the MOT tester know whether the car was originally fitted with one or not? Visually or is there a database?

Cheers
