Exhaust system help

Hi all .
I'm having issues with my exhaust front pipe (flexi joint blowing) it will not separate from the middle box .
I was wondering if a system off a 1.6 16v would fit my 1.8 16v they are both zafira A systems.
They both have the flange fitting on the rear boxs would there be any fitting or engine breathing problems with swapping this over to mine.

Thanks for viewing in advance
