Abstract
A high-performance muffler assembly for exhaust system of an internal combustion engine. The muffler assembly comprises an elongated casing having an inlet port and an exit port, a first pipe disposed within the casing and having an inlet end in fluid communication with the inlet port and an outlet end selectively fluidly connected to the exit port of the casing, and a first valve mounted within the casing. The first valve is selectively movable between a closed position and an open position for regulating an exhaust gas flow through the first pipe. The muffler assembly is operable in a number of different modes of operation including a high-performance mode, an exhaust braking mode, a reverse-flow mode, etc., determined by the positions of the first valve of the muffler assembly.

11. A muffler assembly for an internal combustion engine, said muffler assembly comprising:
-
an elongated casing having an inlet port and an exit port, said casing including a continuous outer wall extending along a central axis of said casing between a front wall defining said inlet port and a rear wall defining said exit port; a first pipe disposed within said casing and having an inlet end in fluid communication with said inlet port and an outlet end selectively fluidly connected to said exit port of said casing; a first valve mounted within said casing, said first valve being selectively movable between a closed position and an open position for regulating an exhaust gas flow through said first pipe; a pressure relief valve disposed inside said casing upstream of said first valve, said pressure relief valve is selectively movable between a closed position and an open position for selectively fluidly connecting said inlet end of said first pipe to said exit port by bypassing said first valve, and said pressure relief valve moves into said open position when a pressure of exhaust gas acting on said pressure relief valve is higher than a predetermined value. - View Dependent Claims (12, 13, 14, 15, 16, 18, 19, 20, 21, 43, 44, 45, 46, 47, 48, 78, 79, 80, 81)
