摘要： An extendible exhaust system is disclosed for preventing exhaust gas seepage into the passenger compartment of a vehicle utilizing a pipe extender that slides along the tailpipe. The pipe extender has a retracted position and an extended position. The pipe extender moves from the retracted position to the extended position when the vehicle travels forward at a predetermined speed. When in the extended position, exhaust flows through the additional length of the pipe extender before exiting the exhaust system. Movement of the pipe extender from the retracted to the extended position may be by airflow traveling past the moving vehicle pushing on a flange acting as a sail against a tension spring. An electromagnet or motor drive system with a movement sensor may also be used to move the pipe extender from the retracted to the extended position.
