cat or no cat?

[crispy]

I’ve had my fd for a bit now and realised it’s got no cat on it and no clue if air pump, o2 sensors and all that stuff is still there since I’ve not checked yet

wondering if I just make it legal and put a cat in it? what is one that will pass emissions if it’s worth it?

engine is mostly stock except a powerfc and exhaust

If your car (like most) is an import, then legally it does not require a cat.

I thought that was only for cars older than 1992 or something? mine is a 1998 import and come to the uk in 2010

IIRC up to mid 95 it's just read at idle and from then to 2002 its read at idle and while rev'ed at some range - I think emmisions are also lower at for 95-02 cars as well. But I don't believe that the 95 to 02 cars legally require a cat as they are classed as grey imports.

All the details can be found in the MOT Inspection Manual: MOT inspection manual: cars and passenger vehicles

8.2.1. Spark ignition engine emissions​

8.2.1.1. Exhaust emission control equipment​

You only need to check components that are visible and identifiable, such as catalytic converters, oxygen sensors, and exhaust gas recirculation valves.


You should reject all vehicles first used on or after 1 September 2002, where original emissions control equipment components are missing, obviously modified or obviously defective.


Vehicles used prior to 1 September 2002 should only be rejected, where a full catalyst test could apply. Use the flowcharts 1, 2 and 3 to decide which emission test is applicable for the vehicle being tested.
