you were correct, This is the email I received from Eric Glazer, NA rep for BMW
"When you buy the full track exhaust including the programming code your bike will be put into a manual warranty authorization status. If a turn signal fails no big deal. If there is an engine failure there could be a problem. The exhaust carries no warranty."
Problem? after spending over 30K I should have no problems.... Im actually going to have start a thread about this because this makes ZERO sense to me.... ok so if thats the case put a manual warranty on it if you use the calibration tool. not just for purchasing an exhaust, ECU, and a code that BMW programs themselves. Thats Bullshyt
