Sport exhaust system type Cat-back by Capristo dedicated to Mercedes-Benz E63 AMG/S W213.
The system uses the original tips mounted in the rear bumper. No modifications are required for the installation of this exhaust; it is perfectly matched to the car.
The entire system is made of polished stainless steel marked T309. This is a type of heat-resistant steel, which significantly improves the exhaust's resistance to very high temperatures.
The end mufflers are equipped with vacuum valves, allowing sound adjustment. This allows changing the exhaust sound characteristics from comfortable to more aggressive.
The valve control is done via a module included in the kit and wireless remotes. An advantage of the Capristo module is the control of the valve openings depending on the engine load, which helps achieve maximum power. The system continuously monitors the pressure in the exhaust system and controls the valves depending on the selected mode:
- CRUISE - the valves open later, with a stronger push of the gas pedal, quieter and calmer system characteristics,
- SPORT - the valves open faster, with every acceleration, louder and more aggressive system characteristics,
- OPEN - the valves are always open.
The advantage of this solution is the adaptation of the valve operation to the driver's driving style. This means that during aggressive driving, the valves open almost instantly, while during calm driving, the system remains quieter and less aggressive (e.g., on the highway). Additionally, the module settings can be individually programmed. The operation of the valves is controlled via a wireless remote, while the module informs about the selected mode through the RDS display in the radio.
