The Cadillac CTS V-Sport Performance Exhaust Kit requires reprogramming of the Active Noise Cancellation (ANC) feature to enhance the sound of the Performance Exhaust System. This is done with a Service Programming System at an Authorized GM Dealer. When reprogramming the ANC, the GM dealer needs to call the Techline Customer Support Center (TCSC). The TCSC will provide a Vehicle Configuration Index (VCI). The VCI is good for only one specific Vehicle Identification Number (VIN).
