As the Zaf is based on the Astra and shares a similar engine would the exhaust tailbox be a poss fit , I have cross referenced the part numbers and they are different but do look identical to me. Could it be a length issue perhaps ?

the tail pipe is longer on a zafira back box,an astra exhaust will fit but it does not clear the bumper which in the long term may cause it to get damaged.
i hope this helps,craig
