I've got a C20XE waiting to go in, but im not sure whether to bin the cat or not (well, leave it off). I asked before, and mos said to bin it, but the guy doing my conversion had problems without ther cat at the MOT station.
Its from a H Reg Astra GTE. Going into a 1996 Corsa. The C20 engine already had a CAT on it when it was stripped from the astra.
I really can't be arised to keep swapping them over at the moment. So shall i store it or fit it?
