The exhaust muffler includes a flat box-shaped body that underlies substantially the width of the motorcycle engine and frame. The rear end of the muffler body has exhaust vents that vent the exhaust downward or laterally from the motorcycle forward of the rear wheel. An inlet neck extending from the front end of the muffle body allows convenient and direct connection of the exhaust pipes from the motor to the muffler body without numerous or complicated bends in the exhaust pipers. The low profile of the muffle body allows the exhaust muffler to be mounted beneath the motorcycle frame without significantly effecting ground clearance.
