Due to Bavaria neither having a league nor a rugby federation in those days, the club had to join the Regionalliga in neighbouring Baden-Württemberg in 1984.

In 1990, the club's long term coach, Rory Donoghue, signed up and a generation change was carried out within it.

MRFC finally obtained a home ground within Munich, Am Hedernfeld and was promoted to the 2nd Bundesliga South in 1992, where it only lasted for one season.

In 2000, the MRFC finally reached the top-tier of German rugby through a third place in the Bundesliga qualification round.

In the 2012-13 season the club competed in the 2nd Bundesliga, finishing in the upper half of the table and qualifying for the play-offs for the DRV-Pokal.

In the 2014–15 season the club finished first in the south-west Liga-Pokal group and lost to the reserve team of TSV Handschuhsheim n the final after a first round bye and victories over RC Dresden and TuS 95 Düsseldorf.

Munich RFC won both the 2nd Bundesliga South and the Bavarian Regionalliga for the first time in the club's history.
