The young side produced a sparkling second half performance for a victory that leaves them in pole position to qualify for the semi-finals.
Declan Cusack kicked two penalties and then added the conversion to captain Peter O'Mahony's try for Munster to edge ahead.
Tom Gleeson scored Munster's second try and although Cusack missed that conversion he made amends with his third penalty just before the end.
