Geoff Moylan's men claimed the bragging rights when they turned on the style to beat the Cookies - despite having two players sin-binned at various stages in the game.
Team captain Fiach O'Loughlin blocked down a clearance kick to pave the way for Shannon's opening try after only eight minutes.
Centre John Clogan followed up to get the touchdown which Tadhg Bennett converted.
But Young Munster got back into the game when out-half Matthew Costelloe jinked past a couple of Shannon defenders for a well-taken 28th-minute try. He added the conversion and Shannon's half-time lead stood at 12-7.
Bennett put over his first penalty of the afternoon, five minutes into the second half, and Costelloe replied soon after with a similar effort for Young Munster.
While scrum half O'Loughlin was sin-binned, Shannon managed a third try. David O'Donovan, who had also been yellow carded just after the interval, was the scorer and winger Stephen Kelly put the icing on the cake with another try two minutes later.
With the bonus point secured, a late penalty from Bennett capped off a pleasing afternoon's work for Shannon.
