Abstract
A muffler for a motorcycle, the muffler including an outer tube and an inner tube disposed substantially within the outer tube. The inner tube includes a first end adapted to receive the exhaust gases from the engine, a second end opposite the first end adapted to release the exhaust gases to the environment, and first and second apertures positioned between the ends. The muffler also includes a mesh tube disposed between the outer tube and the inner tube. The mesh tube defines a chamber between the inner tube and the mesh tube such that the exhaust gases exit the inner tube through the first aperture into the chamber, and exit the chamber into the inner tube through the second aperture. The muffler also includes a noise attenuating material disposed between the mesh tube and the outer tube.
