The Audi R8 4.2L SwitchPath Exhaust sets a new standard. Beyond the hand crafted detail that is standard for every AWE Tuning Performance Exhaust, this one packs a little something special: The R8 4.2L Exhaust incorporates a proprietary mechanical valve system that controls sound volume:

  • Under part throttle and idle, valves route exhaust gasses through a central muffler, keeping sound tame and drone free.
  • At 3/4 throttle application and more, the valves open and the system is unleashed – going into “straight pipe” mode.
  • An in-cabin mounted electronic SwitchPath Remote toggles the mechanical valves between “normal” and “straight pipe mode.” Practical.
  • And for the driver wanting to scream 24/7, we've designed straight pipes which afford a whopping 50lb weight savings (warning: this sound is not for the faint of heart).

In “Normal” mode, the system’s valves are controlled by throttle position, while in “Straight Pipe Mode” the system gets aggressive from the start (ideal for racing and track usage).Performance wise, the R8 4.2L SwitchPath Exhaust has demonstrated:
  • Power gains of +20 hp / +16 ft-lb peak crank
  • +25 hp / +28 ft-lb @ 4700 rpm
  • A 24 lb weight savings
