    Has anyone done such a tutorial? I started pulling the exhaust on my '09 to install a Delkevic de-cat system, but I'm not sure what to do with the decat adjustment cables/motor and O2 sensor?

    You can work off of these instructions they are pretty comprehensive.
    The EXUP cables get disconnected the O2 sensor needs to be reinstalled in the new pipe.

    To allow the cat to drop without a struggle make sure to loosen the front head bolts until they are only held by a few threads.

    Also a set of these are highly recommended to help get to the clamps.

    Thanks much. Those hex keys look good. I have a set of ball-end metric hex keys, but not any that you can put a ratchet on.

    Thanks much for the help! I got it sorted out, and now my 17" tri-oval Delkevic system is installed. That Cat weighs a lot---glad to be rid of it. The beast seems to run well, possibly a little better than stock; hard to say from seat of the pants. The only real complaint I have now is that "launch lag", which I understand requires ECU reflashing to cure. I was going to do that right away, but since I realized it's going to cost on the order of $600, I'm going to hold off and see if I get used to the throttle response as is.

    Well, after reading all the great reviews about Gurued Gear, I went ahead and placed the order for a reflash!

    That's a very good move, it's one of the best mods you can do to a Gen 2 VMax.
