I made a short muffler because a long muffler comes from another company. The torque at low rpm becomes thicker and you can experience the power-up, which makes a clear difference from the normal. The boost pressure will also increase a little. Please judge the sound quality from the video.

It also makes it easier to get on and off from the passenger seat side.
