The stainless steel version of our Radical Racing GP Carbon offered here is one of the best known exhausts for 125cc mopeds. The aggressively shaped end cap, inspired by Moto-GP, stainless steel elements to prevent rust, as well as a dB-killer secured by a circlip are only a few of the quality features that distinguish our sport exhaust for the Aprilia RS4. The manifold pipes are split in two parts. So a catalytic converter can be installed for perfect legalization, this is available separately. The EG-BE certifications are noted on the exhaust silencer and the manifold pipes. So no official papers have to be carried along. To increase the engine performance the catalytic converter can be omitted and/or the dB-Killer can be removed. Idr. are then up to 5 % more power available. However, by such measures the EG-BE expires and you no longer legally drive on the road! The installation of the exhaust system and the catalytic converter is simple and can be done in about one hour.
