What exactly will void my warrenty?

I have a 2001 Sentra GXE. I have a HotShot cold air intake and a custom muffler, not a ricey one, its street legal. Im thinking about getting a perfromance header from HotShots. Does anyone know what exactly will void my warrenty since I only have 44,000k miles on my 100,000 k warrenty. Ive heard that if i get them proffessionally installed it wont void my warrenty

headers will void your warranty not your powertrain but any emmission related faults that may happen after you install the header
