How much of a difference would that really make on a 400? Im considering possibly upgrading mine but not sure if its really worth it or not. Also is it louder? (im guessing it is but the thing only said it made a different noise, not louder one)

You will get a performance gain but it will be so small that you wouldn't notice without a dyno machine.
