If you are not under warranty anymore then there is no need to stay stock. They will service your car just like any other car because it is you paying for it.

It is true that with a catless header you should get a CEL for cat efficiency too low (because you have none) but I have been running a Tomei UEL catless for a month now with no tune and haven't got a CEL of any kind.
