Did you warm up the car b4 you took it to get it smogged? Always make sure its warmed up drive it around for 20mins b4 you take it.
If you did i would suggest a tune up ect.
If not get somone to pass you for the extra $$,,,alot of mexican places will do it.
Or put back on a stock cat or add another on onto the car.
