I have a aftermarket header and intake and cant get the dame CARBEO numbers. Anyone know how I can? Or if I can take it somewhere to have it checked? Stupid thing is the car passes emissions with flying colors, better then stock. Idiots.

 

checke the EO listing of parts and see if you can find an EO number for it htere. then go to the company that makes it and have them verify that it is actually their part.
