Do I need one on my 1992 3b s2 for the mot?

If its before 1st of august 1992 then you can bin it.Im not sure when the last 3bs were registered so you have to check your V5

[Slim m]

date of first registration was 21/08/1992.

not a happy chappy!

thank's for the info.

Most 3B's were registered before the cut off, but not all of them... Last manufacture date was Sept 1992 before the ABYs started rolling in October that year.

Don't forget that a CAT is a not a mandatory requirement for passing an MoT test.
However, the emission levels are set such that, it will be very difficult to pass without one.
There are a few different ways that emissions are tested and it is possible to pass without a CAT fitted.
Obviously if you can find a friendly and performance-motoring enthuiast MoT'er it makes passing easier still........

mine was registered on the 4th Sept 1992 so feeling your pain on this.

As mentioned you dont need a cat in place to pass the test as such but there is little other way to get the car to pass the simple emissions test which yours and mine are subjected to without one it would seem.

You can probably pass by binning the two yuou have (and the restrictive Y setion off the bottom of the downpipe and getting a 100-200 cell replacement cat. These are as i understand it lighter than stock and provide the same flow as not having one anyway, just saveas the hassle of having to change bypass pipes for the cat each year to pass the MOT.

I will hopefully be getting this work done by Longlife in Cardiff at some point fairly soon so will hopefully be able to find out the performance difference and effect on emissions!
