what makes you think GM won't deny a warranty claim if you have long tube headers on your car? because you read that on the internet?
if you have an engine problem and roll in with long tubes, 9 out of 10 times you are going to be SOL. granted, you can get an attorney and fight, but it will cost you more than the repair.
the fact is, warranty and mods are dealt with on a case by case basis and the outcome will vary based on the people involved.
a tune will void your warranty outright because, one, it is stated as such in literature and, two, because you can do a lot of harm with a tune if you do not know what you are doing. you can remove rev limiters, lean it out to the point of melting, i don't know, use your imagination, you can change everything about the car with a tune. GM doesn't know if you only removed a speed limiter or leaned it out like crazy. All they know is that it is changed. They aren't going to play with the depth of the changes. Sort of like if you steal gum from the gas station or rob a bank, either way you are still a thief.
Even though a tune is not illegal, factories don't like them. They are the one paying the warranty bill so they are the ones who get to say what they will pay for.
