AWE Audi R8 4.2L V8 Tuning R8 4.2L Switchpath Exhaust
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).
