So Type S had its MOT today. I found a guy who would "put it through" kind of thing.
So DECATS & IMPORTS. Heres what he said.
Any car with a cat as standard NEEDS A CAT. DECAT=FAIL
Any car after 1995 has to have a CAT.
Any car before 1995 that doesnt have a CAT gets tested on a set amount of CO2. at 3.4% IIRC
Any car that isnt listed on the system for emissions gets put onto a test on a set amount of CO2 at 3.4% IIRC.
A BB6 chassis isnt on the system. I look at the system with the tester and only UK spec cars where on there like VTI, motegi, 2000 motegi or 4ws. So for me it needed a cat and at 3.4% to pass.
Mine had not decat so fail. But the MOT tester and i definately saw a cat under my car. It was cute and furry so pass.
BUT
My emissions were high. The car is running rich. Not massively rich but failed without the cat.
But there wasnt a ford focus in the garage and and my car didnt pass emissions via the fod focus.

Much rather the car run rich than lean.
Anyway only advisery was a N/S upper ball joint play.
