definetaly a pip, i would also recommend a K&N air filter, remove the air box lid, then rejet

I did all of the above... new pipe, rejet, remove airbox lid... as well as... a new front sprocket... one tooth down... I have another completely stock 400ex and there's no comparison in performance between the two... the mods are worth it...
