AWE SwitchPath Exhaust for Audi R8 4.2L Coupe Audi R8 2008-2012

Remember the first time you saw an R8? Your reaction was probably something along the lines of, "what is THAT?" Well, same for us. From that moment forward, our work was cut out for us ? we had to create a masterpiece for the masterpiece. The Audi R8 4.2L SwitchPath Exhaust by AWE sets a new standard. Beyond the handcrafted detail that is standard for every AWE 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. NOTE: Please note that due to the elimination of catalytic converters, this exhaust is legal only for racing vehicles which may never be used upon a highway.If you have an R8 4.2L and you're looking to make one of the most meaningful evolutions available, this is your move.
