In Hamamatsu, we produce products that are used around the world! We aim to become the only company that manufactures mufflers.

We manufacture genuine mufflers (mufflers and exhaust systems) for Yamaha Motor motorcycles. In recent years, we have established original after-service parts “PRUNUS” and manufacture high-quality, low-cost after-service parts utilizing genuine know-how. We respond to overseas markets and local demand through 7 overseas subsidiaries (Indonesia, Thailand, Vietnam, India, and Brazil) in 5 countries.
We can produce a wide range of needs including mufflers for motorcycle, our original mufflers, metal honeycomb catalysts and four-wheel parts.
