An outer pipe is positioned around the inner pipe and has an end portion that extends beyond the upper opening in the inner pipe, said end portion defining an outlet through which exhaust gas exits the outer pipe. A mechanism is coupled with the inner pipe for blocking rain that has entered the outer pipe from falling through the opening in the inner pipe. A ledge mechanism is positioned beneath the upper opening in the inner pipe and between the inner and outer pipes for forming a chamber within which is held rainwater that has entered the outer pipe. A drainage mechanism allows rainwater in the chamber to pass to the exterior of the outer pipe.
