Warranty

Just purchased my '02 duramax and I purchased an extended warranty with it. My question is what, if any, performance upgrades can void that warranty?

All and every, but being realistic I would say you could slide a exhaust system, air intake system, a box of your choice and a fuel system(FASS or a pump not dual cp3's) through pretty easy at most dealerships.
When you say exhaust system, are you saying any exhaust or would it have to be a cat back system?
