Anyone know if and where Nissan specifically recognizes car modifications that will void it's warranty? Particularly the intake/exhaust end...

The intake will void the warranty. Especially when they find out you blew a MAF.

it wont void the entire warranty. nissan has to be able to prove a mod cause whatever failure is in question. like 2k3TitaniumSe said, if you have an intake and blow a maf, they wont cover it. but if you return to stock, then there is no reason why it wouldnt be covered. in my case, ive never had a failure directed at any of my mods but i have had ton of things covered.
