So I called my dealership today and I guess they said the CAI is out of the question. But he said a cat back that fits emission standards would be alright. Now I asked about a leveling kit (just 2 inches) and they said it could affect the ball joints and suspension and they would not cover it if they could prove this was really an issue. Is this really true? I mean maybe a 6 inch lift with 35s or something but a 2 inch leveling kit? Thoughts would help thaks guys.
