your O2 sensor is rite near you cat so it will run crap, thats if you can get it to keep running, corsa Cs are all electrics now and your ECU wont like it. dont bother.
ok on corsa Bs, saxos, vectras coz the cat is in the middle of the car, your cat is basicly on the manifold,
it wont make ya 1.2 any quicker.

lambda sensor is actually in the cat but moving or removing the cat should not effect its readings as it is an electronically heated sensor which does not rely on the heat within the cat to enable it to take accurate readings.
but still what are you going to do?
no point it shifting it unless you are putting a tuned manifold in instead.

i used to have a saxo where the cat is in the manifold and if your ca has 2 lambda sensors then u can de-cat it.
well the saxo had an o2 sensor before and after the cat so the o2 sensor after the cat u just unplug and leave by the battery so it is reading clean air. and the o2 sensor before the cat u place after the de-cat and then block up the whole where the o2 sensor was. i didnt need block the whole as i replaced with a 4-2-1 and it only had one whole for an o2 sensor anyway,
