    I'm running the FMF MegaMax & I like it, it has the discs in it too, but it's not real quiet. Not much else I can tell ya about it though never rode it w/o it so I don't know what the power difference is,.
    Back to the ol' Kodiak 4x4 but at least it's a quad!

    I've got the Supertrapp IDS2 on mine and i like it very well.
    It's tunable also and look very clean.
    It'll smoke my buddy with the FMF everytime.

    hmf all the way. mot to expensive, awsome sound, not to loud, but not to quite. i can easily get the front end up in 2nd now, before i could not, i could probaly get the front end up in 3rd if i go back to stack gearing, and i got a white brothers header because the stock one sucks. here is a pic of it of the quad, i dont have a pic of it on the quad yet, but it looks like a shorty on it.

    White Brothers E-Series and header all the way, nice power gains and not that loud, you can also get the quiet-core insert for it too.

    Supertrapp

    I have a Supertrapp IDS2 also, I have no problems with it.
    It added some good power. For the price ($240) through Rocky Mtn. I find it hard to beat. It comes complete as a whole system, headpipe through silencer.
    That way you get a complete exhaust and still have $$$ left over for other mods.... for me it was a no-brainer......

    I honestly think whatever you choose over stock you will be happy with.... everything is so equal nowadays

    more power is always better
