The sporty Cat-back exhaust system from Capristo is dedicated to the Mercedes-Benz GLA 45 AMG X159.
It is made entirely 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 system utilizes the original tips mounted in the rear bumper. No modifications are required for the installation of this exhaust; it is perfectly fitted to the car.
The end mufflers are equipped with vacuum-controlled valves, allowing for sound adjustment. This enables changing the exhaust sound characteristics from comfortable to more aggressive.
The valve control is done via a module included in the set and wireless remotes. An advantage of the Capristo module is the control of the valve openings based on engine load, which helps achieve the highest possible 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, resulting in a quieter and calmer system characteristic,
- SPORT - the valves open faster, with every acceleration, resulting in a louder and more aggressive system characteristic,
- OPEN - the valves are constantly open.
The advantage of this solution is the adjustment of valve operation to the driver's driving style. Thus, during aggressive driving, the valves open almost immediately, while during calm driving, the system remains quieter and less aggressive (e.g., on the highway). Additionally, the module settings can be programmed individually. 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.
