More Information
Summary:A muffler is described with a housing having an input and an output. At least one plate is disposed within the housing to divide it into at least a first and a second internal expansion chamber. At least one tube is disposed through the plate, the tube having first and second ends with a bend therebetween, the bend altering an orientation of the second end of the tube so that the second end faces an interior surface of the housing. The housing, the plate and the tube establish a path for the exhaust between the input and the output. In addition, the first and second internal expansion chambers cooperate to attenuate sound and the tube assists in sound attenuation and/or affects the path of the exhaust to arrest the discharge of sparks from the output.
