Engineering and driving character
SwitchPath is designed for drivers who want a more expressive exhaust note with valve-controlled changes in sound. The quieter and louder operating characters depend on the valve configuration and the vehicle’s control strategy.
An application-specific X-pipe and valve-equipped rear muffler shape the S58 exhaust note. The valve arrangement provides different sound characters while retaining the vehicle’s exhaust-control behavior.
