Abstract
A muffler includes a housing and one or more tubes secured in the housing. A valve member is engaged in each of the tubes for adjusting an opening size of the tube and for adjusting the pressure that may be generated in the housing such that the mufflers may be secured to various kinds of engines. The valve member includes a ball rotatably engaged in the tube and having an orifice for adjusting the opening size of the bore when the ball is rotated. A filter material is engaged in the housing and may be squeezed for adjusting the output noise of the muffler.
