I would say the loop makes the exhaust more quiet as it provides some restriction and breaks up frequencies and stops drone. The Nismo has less turns, less restrictions so its a little louder. The aftermarket CBEs dont really have any sharp bends so thats one reason they are louder and get the drone but more power.
