    is there a diff in sound and power between the x-4 and x-6 also are those pipes good for 400EX's with no engine mods?

    The x-4 is good for a mostly stock engine, the x-6 is for heavily modified engines.

    If you put an X-6 on a non heavily modified engine will it hurt the stock engine?

    I'm not shure, you might want to check with Sparks on that one.
