AWE Tuning 4.2L Spyder SwitchPath Exhaust (2014+)
The 2014+ Audi R8 4.2L Exhaust Suite sets a new standard. Two options: The sophisticated, versatile valved R8 4.2L SwitchPath™ Exhaust, and the disobedient, unbridled R8 4.2L Straight Pipes.
The SwitchPath™ Exhaust
Beyond the handcrafted 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.
