AWE Tuning 11-12 Audi R8 4.2L Spyder SwitchPath Exhaust 3025-31028

AWE Tuning 11-12 Audi R8 4.2L Spyder SwitchPath Exhaust The AWE Tuning 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. The SwitchPath™ Exhaust line has set a new bar. SwitchPath™ Exhaust highlights include: Designed and manufactured in-house at AWE Tuning Crafted from T304 stainless steel Uses Factory Tips No CEL with full system or straight pipes German Engineered control valves CNC machined V-Band connections One piece, full bolt on system means easy and reversible installation Programming optimized for R8 engine characteristics Lifetime Warranty
