Well, the only problem that you will run into when adding headers is that a lot of times the headers will free up the exhaust so much that the stock tune from the s/c Manufacture might run lean. A lean condition can blow your engine. So a lot of times you have to get a custom tune in order to get your fuel/air ratio where it should be. Once this is done, it will not be able to get pass smog.
You got to remember that when the s/c manufacture designs their systems, it is made for stock engines. Anything to improve the airflow will effect their tune and to be safe you should get it re-tuned.
