Stage 2 consists of the factory front pipe with catalyst deletion, replacing with the free flowing 3” cat-less front pipe as found above in the stage 1+ package. In the quest for further power we then turn to the next restriction which is the case of the Astra J VXR is the original equipment air intake/air box. We completely remove this and replace it with a huge free flowing AEM non oiled Dry Flow Filter. This is mounted to a free flowing air flow meter housing which features a built in air straightener so correct air mass values are relayed to the ECU, finally this assembly sits within a heat deflector shield. Once fitted we install and optimise our Exclusive Courtenay Sport software on our rolling road to take full advantage of the improvements and provide full power and torque graphs.
