The AWE Tuning 2013+ R8 4.2L 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.









The AWE Tuning 2013+ R8 4.2L Straight Pipe Exhaust

Do you find even our R8 4.2L V8 SwitchPath™ Exhaust too docile? Maybe you need to meet the AWE Tuning R8 4.2L Straight Pipe Exhaust.

This system unlocks the same impressive power gains of 25 hp and 28 ft-lbs of torque as our SwitchPath™ Exhaust, but sheds even more weight over the stock exhaust system, for a total weight loss of 55 pounds -- because lighter is faster.
Be warned, though. The sound from the straight pipes is not for the faint of heart, small children, or small pets, and there are no “switching options” available with this addition.



Scared? Take a step back to the head-turning, yet sophisticated SwitchPath™ Exhaust.

AWE Tuning stands by this product with a lifetime warranty, however, the straight pipes cannot be returned or exchanged based upon sound satisfaction.

If you have an R8 4.2L and you're looking to make one of the most meaningful evolutions available, these are your options.
