    Dont do it, thier on there for a purpose and you violate several federal and state laws if you do.
    This shouldnt even be a discussion.

    Don't remove them...

    Replace them with high flow CAT's...

    Best of both worlds.

    Not a good idea. It will void whatever warranty you have left, set off your ses light and really not improve your performance.

    It's also like a $25k fine if they catch you. :great:

    truck cats already are they are rated for high HP already, no need to go and buy "high flow", unless your cats are actually clogged there is no reason to replace them
