    Your ski came stock with a wet pipe. The dry pipe is an upgrade to what you have. The wet pipe injects water into the pipe to quickly cool the exhaust gases. The dry pipe helps add a boost in power by not cooling the expanded gases and the reflex action in the pipe pushes unburned gases back into the cylinder before the exhaust port closes. Kinda like super charging the cylinders for more power.

    It only injects a small amount of water (780 uses a 1mm orifice) into the exhaust chamber. Not enough to worry about having to expel that much.

    The wet pipe creates a good bottom end torque vs. the dry pipe that creates a good HP increase at higher RPM.

    For the best of both worlds, a dry pipe with a water injection unit would be ideal. MSD makes a WI piece for around $125 I believe.

    For an SLT, I'd suggest staying with a wet pipe for bottom end grunt.
