As a dealership employee I have never seen a warrany not honored because of an exhaust mod or header. The tune on the other hand can change many things on the car that goes beyond o2 sensor placement and such so that can be a little more touchy. I will be installing kooks long tubes and high flows this winter with a tune. I am not too worried as i dont plan on beating on my car. You do not have to tune for the headers and such but your check engine light will come on because your readings from your o2 sensors will change.
