An exhaust gas temperature control system for a two-stroke engine, the exhaust gas temperature control system including an electronically controlled water injection system. The electronically controlled water injection system includes a water supply conduit section for supplying water to a solenoid valve, and a spraying conduit section for injecting water into an exhaust pipe to thereby control exhaust gas temperature, and hence sonic wave speed within the exhaust pipe. A through-filter is provided as a splitting junction to provide filtered water to the electronically controlled water injection system and unfiltered water to the engine for cooling. A smoothing device in the form of an elastomer hose made of low durometer material or a pressurized bladder is included within the spraying conduit section for maintaining smooth water pressure within the water injected into the exhaust pipe. Additionally, a capturing device in the form of a pressurized bladder and check valve is provided within the supply conduit section in order to maintain ample water pressure supplied to the solenoid valve.
