Leaving Atlante in 2000, he represented Chivas, Irapuato, and Veracruz in the closing years of his career.At international level, he earned 49 caps for the Mexico national team between 1991 and 1995. Ramírez Perales made his international debut against the United States on 12 March 1991.

Likewise, Ramírez Perales started all four games at the 1994 FIFA World Cup, lining up next to Claudio Suárez in the heart of the Mexico defense. He was recalled for the 1995 Copa América, but only appeared in the opening game. Ramírez Perales earned his final cap on 6 July 1995 in a 2–1 loss against Paraguay, and was replaced by Manuel Vidrio in central defense for Mexico's remaining matches in the competition.In addition, Ramírez Perales played three games for Mexico at the 1985 FIFA U-16 World Championship in China.
