The exhaust system for the Zafira OPC (Z 20 LET engine) has an additional separation point downstream from the pre-catalytic converter, in contrast to the Astra-G Coupe.
The separation point comprises a flange connection.
The exhaust system in the Astra-G can be retrofitted with the separation point. This reduces the repair costs in the event of a repair because the components of the exhaust system can be replaced individually.
