Abstract
A high performance muffler is used to modify sound waves of exhaust gases generated by a high performance internal combustion engine. The muffler has an inlet for connection to an internal combustion engine exhaust system. A muffler body is connected to the inlet. The muffler body has a shell which has a width greater than its height. The shell includes a pair of spaced apart opposed panels. An outlet is connected to the muffler body to receive exhaust gases from the body. The muffler body has a first expansion chamber adjacent to the inlet. The first expansion chamber extends across the width of the muffler body. A first reduced opening is in the muffler body extending across the width of the muffler body. A second expansion chamber is in the muffler body adjacent to the first reduced opening. The second expansion chamber also extends across the width of the muffler body. A second reduced opening extending across the width of the muffler body communicates with the second expansion chamber. The second reduced opening and first reduced opening cooperate to direct flow of the exhaust gases through the muffler body in a sinuous path. A third expansion chamber extends across the width …
