Cam, tune, NOS sure...but I really doubt LT headers and exhaust will. But ask your dealer.

False. You have no offical GM powertrain warranty with LT's. They have no prove nothing other than the LT's are on the car.

'Longtube headers' denotes moving the catalytic converters, which is also against federal law.
