The Naraku Crossover Exhaust is a performance-oriented replacement exhaust tailored specifically to the QMB139 4-stroke 50cc engine. The crossover pipe design targets top-end power gains over the stock exhaust, while the real carbon fiber silencer keeps the look clean and stealthy. Designed to European road standards — removing the manifold restrictor delivers a significant additional performance improvement.
