    Just to put this one to bed.
    Cats fitted. My local specialist said they fitted fine with no problems at all.

    The old cats (OEM ABY) were shagged, chunks and bits of honeycomb matrix stuff rattling around and a couple of big chunks blocking both pipes at the rear.
    Car flies again, well, it did until it sprung a water leak out of the top rear rad hose (original hose, split just were it connects to the water manifold). New SFS replacement ordered, thanks Mark

    Looking at the MOT emissions test results, they seem to be working fine.

    Engine temp - 89°C

    Fast idle test,
    Engine speed - 2600rpm
    CO - Max 0.20% - reading = 0.00%
    HC - Max 200ppm - reading = 8ppm
    Lambda - 0.97_1.03 - reading = 1.01

    Natural idle test,
    Engine speed - 850rpm
    CO - Max 0.30% - reading = 0.00%

    I guess I can't try and top myself with the CO fumes from my exhaust then

    @ Lee, no reply to my PM the other week matey.
    The old cats I've kept from being binned. They are yours FOC if you want them. They aren't any use to me mate. They'd only get chucked.
