    get rid of the cat = yes
    for that year ski, there is a chip/resistor readily avail, use that for the Cat/temp sensor...

    Yes do it for reliability but it won't give any extra HP. In fact the motor will drop 50 RPM because the D plate has a little less back pressure than the cat con.

    its a fairly easy mod...also a no brainer...they can be bought on here, less than 100 for plate and chip(not really a chip, just a sealed resister in male plug.) check the faqs for instructions, nice easy to follow tutorial by cajundude...also as mentioned, no real gain unless cat is severly restricting exhaust now.

    Here's the D-Plate. I believe the R&D plate is favorable over the Riva plate due to a slightly smaller hole size...

    And here's the Cat Temp Sensor.

    Use coupon code "Greenhulk" at checkout for 10% off.

    And finally, here's a step-by-step to get the stinger off. Once you get the stinger off, it's as simple as removing some bolts, putting the D-Plate in place, and bolting it in. You might also want to get some "Copper Spray A Gasket" to put on the gaskets of the stinger. Just to make sure everything is sealed well.
