ABSTRACT:
A muffler has a muffler body within which is located an intermediate duct pipe colinear with the exhaust and tail pipes, so that exhaust gas from the exhaust duct pipe can pass through a main flow route in the intermediate duct pipe in a substantially straight line without reflecting. An inner or by-pass pipe forms a gas by-pass and has gas flow restriction elements.
