the rule book said that exhaust and intake were significant mods that wouldn't change your class. i don't think like basic stock replacements (ie. e-fan conversion) would be enough to put me in another class. i was just seeing what you guys thought. the only thing is that the exhaust they say is ok is cat-back and i don't have cats.
