Add On Policy?

Posting in all threads as it relates to most Genesis owners. I have no plans on changing my GV70 in any way now; but see lots of exhaust mods, electronic transmission shift items etc. But what happens to a Genesis Warranty and at what point does it cause it be invalid? Just curious, as the standard warranty is quite extensive and much longer than the competition....

Maybe I have missed something as to what is okay or not without busting your warranty?

Thanks in advance!
