well if you get performance mods from the dealer than it good. But usually it will just void that specific part, but a lot times if covered by the aftermarket company. Now heres an example. They will void the warranty for everything behind something in the system. So lets say you get exhaust theres nothing behind it in the system so they will just not cover your exhaust. But if you get headers then everything behind that will not be covered so your cats, exahust. If you did a charger well then the whole motor. But like others have said they have to prove that it did it. But they would probably have an easier time proving it then you trying to disprove it.

My opinion, if I do mods they will be GM performance parts at the dealer while I have the warranty. Now once its up then i am thinking about doing a charger. Plus wait till i got the car paid off and its mine, i just dont think its the smartest thing to dump a bunch of money into something you dont own.
