You shouldn't have any problems with the N55 mids, in fact with regard to getting into limp mode you shouldn't have problems with any of the alternative mids. Maybe if you have a tune which will give you more boost but you don't compliment it with additional cooling hardware then you might have this problem, not with mids or rear mufflers only.
