Abstract
A protective cap for an exhaust pipe. A U-shaped clamp is disposed around the exhaust pipe adjacent its outer end and an arm which carries a lid is pivoted to the free ends of the clamp. The lid is adapted to enclose the outer end of the exhaust pipe and can be moved to an open position by the pressure of the exhaust gas. A stop is mounted on the ends of the clamp at a position between the pivot and the exhaust pipe, and is adapted to be engaged by the lower thin edge of the arm to limited downward movement of the lid and space the lid from the end of the pipe to reduce noise.
