A muffler for reducing the sounds of combustion gases exhausted from an internal combustion engine including an elongated fluid passage extending between an inlet and an outlet such that the outlet is in fluid communication with the inlet. Further, the inlet being connectable with the gases exhausted from the engine and the outlet being connectable with the atmosphere. The muffler further including an outer tank surrounding the passage and a tubular connector having a first end in fluid connection with the passage and a second end in fluid connection with the tank such that the connector produces a fluid connection between the passage and the tank. The connectors having a perforated resistance plate to restrict the fluid flow between said passage and said sound chamber thereby reducing the severity of the sound or fluid pulses entering and exiting said sound chamber, perforations in said perforated plate forming an open portion of said plate and said open portion being less than 60 percent.

Exhaust muffler

A muffler for reducing the sounds of combustion gases exhausted from an internal combustion engine. The muffler including an elongated fluid passage extending between an inlet and an outlet such that the outlet is in fluid communication with the inlet. The inlet of the muffler being connectable with the gases exhausted from the engine and the outlet being connectable with the atmosphere. The passage having a first side region and a second side region circumferentially spaced from the first region with a fluid passage in at least one of the first and second side regions. The muffler further including a side attenuation sound chamber adjacent the at least one of the side regions wherein the chamber is circumferentially spaced from the other of the at least one side region.
