Generally speaking, anything that is going to change the engine, it's operating parameters, or design is going to void the warranty.

The grey area is the dealer you take it to. Some may not blink at headers or catch cans, intakes. Some may not even blink at an ECU tune, for certain warranty repairs. It's when they need to get approval from the mothership the issues begin. GM may want a datalog of the ECU, or they may send out a warranty rep to inspect the car. This is when it is out of your mod friendly dealers hands.

Also keep in mind that even though your dealer is mod friendly, not all are. If something happens while out on the road, GM roadside may take it to the nearest dealer, not your favorite dealer. They might call you out on the mods.

If warranty is a priority, then, outside of the intake, mufflers, and wheels, I'd leave it the way GM designed and built it.
