The ship exhaust pipe SAE j2006 R1 has a main body. An inner shell is integrally formed inside the main body. In the inner shell, four air inlets are arranged relative to the air outlet of the engine, and an air outlet is formed at one end. The main body is also provided with liquid inlet and outlet holes for the inflow and outflow of cooling liquid. The inner shell is a diversion pipe body extending from the air inlet to the air outlet respectively. The utility model is an exhaust pipe which improves the exhaust efficiency and engine output effect by changing the internal structure of the exhaust pipe, and increases the cooling liquid capacity in the exhaust pipe by about 30 to 40%, so as to improve the cooling effect of the overall exhaust pipe.
