The old warranty question. To be positive, you should always consult with the service manager at your dealership first. For the most part you are fine with an intake and a catback exhaust. Most dealers will let you get away with high flow cats and some will let you get away with headers and a tune. Just remember all dealers are different but changing your exhaust shouldn't effect an issue you're having with the radio, power seats, etc... Most dealers are cool enough to reconize that.
