The dual mode exhaust is identical(in operation, not construction) to the C6Z06 exhaust. It doesnt offer a louder or more aggressive sounding idle, quite the opposiste, at idle and cruising rpms its very mild and after the control point(3000-3500rpm) the valves open and the exhaust becomes louder.
Either install one of the switch kits, remove the fuse, or go aftermarket.
