This particular exhaust system is designed in such a way in order to be used along with the OEM waterbox according to the new Japanese regulation. Therefore, two times Pro freestyle champion Fumikazu Watanabe has rearranged the battery and the special fuel tank position in order to concentrate the masses around the engine and enhance the overall stability of the craft. The new Dry Pipe is specially designed for big bore engines and can be used for freestyle or close course applications. This exhaust system costs 152.000yen in Japan.
