A high performance exhaust muffler which improves engine power and economy as well as providing a smoother engine performance. The muffler comprises an exhaust gas expansion section and a tubular baffle section closed or partially blocked at one end, its open end being attached within a smaller end of the exhaust gas expansion section to allow gas to pass directly into the exhaust gas expansion section and some to pass into the baffle section causing a weak back pressure to pulse back along the baffle tube.
