Series tube Ø 70 mm - REMUS tube Ø 70 mm
The flap is controlled via the vehicle's standard electronics and standard actuator.
When installing REMUS sports silencers, cat-back systems and replacement cat pipes designed for use on closed tracks, it is advantageous to perform an ECU remapping in order to exploit the optimal performance of the exhaust system and prevent the check engine light from illuminating.
The use of racing products and products that do not have EC approval is not permitted on public roads or within the scope of the STVO/STVZO!
