Abstract

An exhaust system (10) includes an exhaust manifold (14) coupled to an engine (12), a decoupler (16) including an inlet coupled to exhaust manifold (14), an outlet extension (28) coupled to an outlet of decoupler (16), and various downstream components such as a catalytic converter (20), exhaust pipe (18), bottle resonator (22), and muffler (24). A resonator shell (30) is positioned to lie in outlet extension (28) to define a resonator chamber (42) in communication with airborne noise frequencies associated with exhaust gas passing through outlet extension (28).
