As with any aftermarket (unless it's a GM accessory) you will void the warranty on that part i.e. exhaust, cai now if you have an engine failure GM would ahve to prove that the exhaust or CAI caused the engine to die (just an example if they said the CAI caused the problem).

I myself opted for a 7yr 100k warranty I will be doing an aftermarket exhaust and the GM CAI.
