If you are fully catless, you are going to need primary and secondary cats placed back on the car to pass.....
2 other options:
- chat privately with some of the forum members here and find a "guy" who will pass you
- hit up a couple of the performance shop sponsors on this forum who have full OEM exhausts sitting in their warehouses from recent swaps they have been installing. Likely, for a small labor charge they will swap out your exhaust setup with OEM (from one of the several they have just sitting around), have you run down the street, get smogged, and come back and put your setup back where it belongs....on your M!
Either way, good luck to you!
