This exhaust system for the Aprilia RS4 125 of the Italian brand Arrow does not only look good, but without a catalytic converter it achieves an output of up to 14 hp at 12,800 rpm. The ABE of the exhaust system loses its validity in this case, however. The rear silencer is made of high-quality stainless steel as well as brushed, matt aluminium. The installation of the exhaust system is uncomplicated and can also be carried out by laymen: After removing the fairing, the exhaust system is simply attached to the original manifold. The corresponding mounting material is included in the scope of delivery. However, the catalytic converter (11013KZ) is not included. For this exhaust an EG-BE (type approval) is necessary.
