new or used? if it's new than yeah, you'll be saving a few bucks (probably a little over $100-150 as far as i can tell.) if used... depends on the condition. if it's all in good repair (minor external blemishes, but all in working order with no leaks) than it might be worth looking into. be aware that the FC race header has a tendancy to rust, even the ceramic coated one.
Edit: also keep in mind that a race header is illegal in most states and will cause you to fail both visual and emmissions testing. meaning you're gonna have to swap it out come time for testing.
