Apparently the exhaust I'm selling has a decat...but what is it? A bit of pipe at the end of the exhaust, this much I know but what does it do/what's it's purpose for being there? :bananasmi

Will it matter for the MOT that there is no cat on a car if it was meant to for that year?

Oh and from what year did Cav GSi's have cats?

All cav gsi's had a cat, pretty sure - you know who can say for sure.... :Cool2:
Highly unlikely it will pass a cat test, without a cat, if it requires one.
Not having a cat fitted in itself is not an mot failure, the highly likely fact the emissions will be high obviously will be a failure.
In all the cars I mot'd, only one non cat would have passed a cat test, old 2.3 granada at that :eh

As above Biilly :) On your old H Reg, it were more than likely down to either an engine swap, or garage advice.
