Malossi RX Exhaust for 250cc – 300cc Kymco Xciting COMPATIBILITY: Xciting 250 Xciting 300 Malossi is pleased to announce the new RX exhaust systems for maxi scooters! It’s a new line of homologated exhausts suitable for a wide range of engines (up to 400 cc). A genuine concentrate of technology, but a very reduced weight: an RX exhaust weights approximately 3.5 kg only! This weight reduction may even reach 3 kg depending on its application. Internal components and DB killer were completely re-designed in order to achieve the best performance, but keep the noise within law limits; three silent-blocks allow to reduce vibrations, while a shaped plate and three fasteners on the silencer ensure an easy and quick assembly. **
