Racing Exhaust System

This system represents a full step in exhaust tuning, balancing price with optimum performance gains. This exhaust system delivers measurable improvements in power and torque. It provides a gain of +3.0 kW at 11200 rpm and +4.9 Nm of torque at 4500 rpm. Furthermore, it significantly reduces weight by -2.4 kg compared to the stock exhaust, contributing to improved handling and performance. The system also produces a distinct racing sound output, measured at 103.7 dB at 5500 rpm. Installation is estimated to take 90 minutes. It is important to note that when installing this Racing Line exhaust system on Euro5+ motorbikes (equipped with 2 lambda sensors), the engine check light may appear due to deviations from stock catalytic converter parameters. Additionally, THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE. This exhaust system is specifically designed for the Aprilia RS 660 and Tuono 660 models, including E5+ variants from 2024 onwards. While some sources suggest it may fit earlier models or other variants, it is crucial to verify fitment for your specific motorcycle.
