The REMUS sport exhaust for the BMW 3 Series G20 G21 M340i and BMW 4 Series F22 M440i xDrive offers a significant increase in performance and torque due to reduction of back pressure and flow optimisation. Less weight and the well-known sonorous REMUS sound are additional features, which distinguish the REMUS sport exhaust from the stock exhaust.

During testing and as part of Remus' extensive R&D process the Racing cat-back system huge gains of +19.3 HP / + 43.8 Nm and a 5.1 kg weight saving!

The system includes an additional original BMW actuator and a Y-cable for connecting both actuators with the onboard electronics of the vehicle. The activation of the valves is carried out using the original vehicle onboard electronics.
The use of racing products and products which do not have EC approval is generally not permitted on public roads.

When fitting REMUS sports silencers, cat-back systems and cat replacement pipes designed for use on closed tracks, it is advantageous to carry out an ECU remapping, in order to exploit the optimum performance of the exhaust system and to prevent the check engine from lighting up.
