Astra MK4 Z20LET Milltek exhaust fit Z22SE

Hi, as above, does anyone know if the cat exhaust section would fit the 2.2 mani with the turbo down pipe removed? Or would some extra work be needed? From photos it looks similar.
doubt it will fit as the z20let has its exhaust from front of engine where as our decent engines have the exhaust from the rear.
sure it could be made to fit with some cutting and weld though
