size is your exhaust?? if it's 3" piping, it's too big (for an NA) and you'll lose back pressure. most use 2.5" piping for their exhausts i believe, but even that with headers is not too much air flow. remember, on most stage charts, headers come after an uprgraded exhaust, so you won't have anything to worry about with them having too much airflow...
