The Muffler is placed in the direction as shown in the main drawing of our link, and the exhaust port is on the right side, so it can be judged as the right exhaust pipe.
On the other hand, if the Muffler is placed in the direction shown in the main diagram, and the exhaust port is on the left side, it is the left Muffler.
Before placing an order, please carefully check the physical picture on the link to ensure that the exhaust pipe is suitable.
