I have to say, that is what I have been led to believe also.......Anyone any advice on this matter ???

Your downpipe cat may have curled up and died? The PPP cars definitely do not have mid-section cats yet still pass MOT's on standard downpipe cat. Do you use octane boosters and if so which one? Some kill the cat. Swapping mid-sections for the day may be only solution, and alot less hassle than doing the downpipe.

Will a car definately pass with just the centre cat?

got a Magnex De-cat and back box and its failed mot, has anyone else had this, what can I do other than put mid section back on, told to hammer the car up and down motorway before re-test, I did this last year and it was ok but this was before mid section was put on. HELP

Like I have said all along - you NEED at least one CAT in place to pass, legally that is!!

Stick a £50 note under the windscreen wiper - or, simpler, put the cat back on!!

yeh but thers 2 on it one at the front and one in the middle, i've been told with the middle off it should be okay

Its UK94 only pipercross air filter running on unleaded, no octane boosters.

It is possible on a car of that age that the lambda sensor is buggered.

Dont know about uk cars but on wrx sof that vintage, the lambda sensor is in the headers which means it has to survive much hotter temperatures than thopse in the downpipe.

If buggered then the jecs will run the car very rich, and so the emissions will probably be off the chart.

Replacing the lambda sensor could pass you your mot but also, will improve your fuel economy if it is indeed knackered which I suspect it is.

ITS PASSED, after going up the M62 in 3rd and almost red lining it failed again but after deliberating what we should do next he ran it through again and its passed.
