Two-piece trim apparatus for use with fluid regulators are described. In one described example, a fluid regulator has a regulator body and a first seat ring to provide a first flow characteristic disposed within the body and defining a fluid orifice. The first seat ring is interchangeable with a second seat ring that is to provide a second flow characteristic different from the first flow characteristic. The fluid regulator also includes a first cage to provide a third fluid characteristic and removably coupled to the first seat ring. The first cage is interchangeable with a second cage that is to provide a fourth fluid flow characteristic different from the third flow characteristic. The first cage can be selectively coupled to the first seat ring or the second seat ring and the first seat ring can be selectively coupled to the first cage or the second cage.
