Installation and Usage

Due to the size and weight of a V8 catback system, installation by a professional exhaust workshop is strongly recommended. The car should be raised on a hoist and the exhaust fully cooled first. Valve actuators need to be connected and tested to make sure they work with the vehicle's drive modes. After fitting, check alignment of the tips within the rear bumper and confirm all joints are sealed.
