Audi R8 V10 - Exhaust Valve
This R8 like many new cars is equipped from the factory with a valved exhaust; meaning that the volume of the exhaust can be "adjusted" depending on whether the car is being driven in sport or comfort mode.
The customer wanted the exhaust to reamin in the louder mode at all times; no problem. The valves were forced to stay in the open position therefore achieving the desired result. This is 100% reversable, and has no adverse results such as any warning lights.
