if i install a CAI, L/T headers, and a cat-back w/ x-pipe without a dyno tune, will i be doing any harm to my car?

i want to be able to swap the old exhaust system without having to retune it everytime for smog tests later down the road. I live in california.

Instead of the long tubes try the jba shorties because they are smog legal. To take care of the cats I will be getting the jba mid pipes without cats because it is an easy bolt on and when it comes time for smog just take the time and unbolt the midpipes and bolt the cats back up.
