Extremely loud sound and comfortably quiet become one with iPE The Mercedes-AMG G63 V8 refined with an iPE Innotech Performance Exhaust system produces an extremely loud and aggressive sound as well as a comfortably quiet cruise by the push of a button when wished for. Our Valvetronic exhaust delivers both power and dynamic valve control to the driver's seat. The full system includes the remote capability to command 3 different modes: on, off, and auto. In on mode, the valves are fully open for maximum flow and power, releasing a unique and breathtaking sound. In off mode, the valves are closed and volume is reduced for a comfortable cruise. The auto mode enables the system to detect the engine RPM and fuel pedal signal to automatically adjust the valve movements for a dynamic driving experience. Each part of the exhaust system is individually designed to perfectly fit the Mercedes-AMG G63 Our unique design overcomes the limits set by the stock exhaust, so that performance, sound, and driving pleasure can be increased dramatically.
