I have 2 choices:

1)fit standard post 93 parts and the car does not have to undergo emissions testing as its assumed it would pass.

2)present it for testing with the greys fitted and pay $2500 for an emissions test which it wouldnt pass (even with Stu's closed loop control)

The easiest and cheapest option all round is to pick up the necessary std parts here 2nd hand and just throw them on to get it complianced, then bin them and refit the decent bits!!
