ABSTRACT:
An improved exhaust cutout device is provided for an engine having a collector pipe from a header and an exhaust pipe to a muffler. The device consists of a mechanism for diverting exhaust gases. Elements are for fluidly coupling the diverting mechanism between the collector pipe and the exhaust pipe. A structure is for operating the diverting mechanism. In a first operable position, the exhaust gases can pass between the collector pipe and the exhaust pipe to pass through the muffler for a quiet exhaust for city and restricted areas. In a second operable position, the exhaust gases can exit directly into the atmosphere for open road, racing purposes and country driving when more speed, more power and gas economy is required.
