Firpo rejected the offer. The members of CD Luis Ángel Firpo acquired land near Sergio Torres creek to develop and build a stadium. Their first football manager was Manuel "El Zancudo" Segurado. In 1941–42, they were named the best team in eastern El Salvador and were allowed to challenge for the national title. A year later, Luis Antonio Regalado brought the club further prestige when he was chosen for the El Salvador's national football team. After him came the Zamora brothers (Ricardo and Miguel), the Quinteros brothers (Leonidas and Lázaro), and Ramón and Mario Águila. Financial instability plagued Firpo in the 1950s and 1960s, and they dropped out of the top flight on three separate occasions. In 1972, Firpo became a permanent top-flight fixture. Golden generation In the 1988–89 season, the team hoisted the league title for the first time. The team finished third in the regular season, but the club nonetheless dismissed Argentinian coach Juan Quarterone before the playoffs. In his place, they hired former player Julio Escobar. Escobar justified the club's faith by leading the team through the championship round and into the finals. Their match against Cojutepeque was drawn 2–2 after extra time, setting up a penalty shootout. Firpo prevailed 4–3, with Leonel Carcamo scoring the winning penalty. In the 1990 final, the team lost to Alianza but won their second crown in 1991. That season saw Firpo go on a 30 match unbeaten streak and defeat Aguila 1–0 in the finals. Marlon Menjívar scored the only goal. The following year, Macedonian Kiril Dojčinovski took over the coaching reins of Firpo and led them to back to back titles. The stars of this run were Raúl Toro, Raúl Díaz Arce, Mauricio Cienfuegos, Celio Rodríguez, Leonel Cárcamo and Fernando de Moura. They defeated Alianza in both finals, giving the club four championships in five years. Soon after, Leonal Carcamo donned the captain's armband and the club continued to play at a high level. They reached either the semi-finals or finals every year from 1994 to 1997, then won the championship again in 1998. That win came over FAS 2–0, with the goals being scored by Raúl Toro and Abraham Monterrosa. Firpo won another championship in 1999, beating FAS 5–4 on penalty kicks. In 2000, Club president and owner Sergio Torres died the week before the final match against ADET, and the players dedicated the match to his memory.
