A toilet has a trapway extending between a bowl opening and an outlet opening. The trapway defines a curved water dam region above the bowl opening, a down leg, and a straight out leg between the down leg and the outlet opening. The out leg has an air dam cavity such that the trapway has an increased cross-sectional area at the air dam.
