Show original supplier description
The Arrow Racing 71765MI is a high-performance stainless steel exhaust collector specifically engineered for the KTM Duke 390 (2021-2023) and RC 390 (2022-2023) motorcycles. It features a 74mm outlet diameter and is designed to eliminate the Original Equipment (O.E.) catalytic converter, allowing exhaust gases to flow more freely. This results in a noticeable increase in power, particularly at higher RPMs. The Arrow 71765MI collector is designed for direct fitment with your motorcycle's original silencer. For riders seeking further performance enhancements, it is compatible with Arrow's PRO-RACE, GP2, or INDY RACE silencer lines. The collector is supplied with all necessary components for installation. Key specifications include: Collector material: Steel, Outlet diameter: 74.00 mm, CO sensor: NO, Oxygen sensor: YES, Noise reducer: NO, Weight: 1.20 Kg. This product is not approved for road use.
