If the car you ripped the xe out of did not have a cat your laffing as u dont need one if you do take the old cat/zorst to a custom zorst place and they will sort u out a system..
I am going to cut the flang off the xe manifold and bend some 2.25" zorst pipe to back box and weld it on!! (as mine donner car was a pre car cavalier)

you just say it's a none cat enigne and they'll believe you.
Just get the engine in, and then have a full 2.25" system on there, 2 box preferabley

No, cause there's no date stamped on the engine that's easy to see unless you're looking for it.
Just a) ask them to do an emissions test on a 2L 16V corsa [they can't reverets to pre-cat emssisons test]
Or make up a boggus receipt saying it's from a '89 MK2 astra GTE or something, andf put your signature and make you joe bloggs or something.
