The AWE Tuning SwitchPath Exhaust System gives the best of both worlds: a Touring Edition exhaust note when exhaust gasses are routed through a central muffler and Helmholtz Resonator, and an aggressive Track Edition exhaust note when the valve system opens and exhaust gasses are routed straight through from the turbocharger.
The included SwitchPath Activator is located discreetly in the ashtray, on the center console. This placement allows the activator to be concealed and undetected to the untrained eye. Form and function, united.
The system changes personality by employing AWE Tunings proprietary mechanical valve system. In essence, the AWE Tuning SwitchPath system is a Track Edition and a Touring Edition all in one:
Option one: do nothing. The SwitchPath system changes volume from Touring to Track levels naturally based on boost levels. So when you hammer it, it hammers back.
Option two: press it: With a press of the included AWE Tuning SwitchPath Activator, you can be in Track from the word go, regardless of speed, throttle or boost. When you want to turn heads in traffic.
As exhaust gases exit they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.
The AWE Tuning SwitchPath Exhaust systems on-demand adaptability can take you from subtle to screaming in an instant. It truly is the most unique and versatile system on the market today.
