The 2013+ 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.

SwitchPath™ Exhaust highlights include:

• Designed and manufactured in-house at AWE Tuning 
• Crafted from T304 stainless steel 
• Uses factory tips 
• No Check Engine Light - Guaranteed
• 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

Please note that due to the elimination of catalytic converters, these exhausts 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, these are your options.
