The problem with all of this is when it gets to the lawyer level. How deep are your pockets? That said I doubt Nissan will make too big a deal out of a cat back exhaust or intakes.
Porsche would void your MAF sensor warranty if you had K&N's on the car. My service advisor told me to save my stock filter in the event I had a MAF or cat failure. Glad he did because a cat failed, $3200 for the pair.
