The REMUS cat-back solution fits within the original exhaust outlets, with integrated valve for the Audi RS6 / RS7 type 4G is designed to work in perfect cooperation with the stock catalytic converter of the engine. Reduced back pressure and optimized flow dynamics grant a significant increase in power and torque in combination with the well-known sonorous REMUS sound. Due to lightweight construction and sophisticated materials, a reduction in weight can be seen in comparison to the stock exhaust system.
The supplied actuators activate the valves to factory preset positions via the vehicle onboard electronics.
