A vehicle with a two-stroke engine includes a system for rapidly heating an exhaust pipe. The system may include a heating mode signal generator, a sensor, and a controller. Activation of the signal generator signals the controller, which, in turn, determines whether the engine RPM falls in a range such that the vehicle remains stationary. The controller may then set the engine ignition timing to a heating mode range that rapidly heats the exhaust pipe system. The ignition timing may be after top dead center in the heating mode. A method of rapidly heating an exhaust pipe is also disclosed.
