Blues make seven changes from the side beaten in Ravenhill last weekend, two of those positional and two forced by injury to Chris Czekaj (shoulder) and Tom James (calf) while Andries Pretorius returns from a knee injury to take over from Xavier Rush who slips to the bench.
"Similar to Ulster, all Munster sides are very disciplined and structured," said Blues coach Gareth Baber. "They will be physical and want to play in the right areas by implementing a good kicking game.
And in out-half Ian Keatley Munster have the ideal architect to implement Baber's prediction. He has looked particularly sharp in the opening games, particularly in Firhill when his raking touchfinds kept the Warriors pinned down in their own half for long periods.
Behind him Johne Murphy is enjoying a return to form and his booming clearances have also been a feature of Munster's impressive rearguard while the Peter O'Mahony led pack, with veterans Mick O'Driscoll and James Coughlan hugely influential, improve with each game.
Games between these two sides in recent times have been close run affairs and this one will follow suit.
Munster: J Murphy; D Howlett, D Barnes, L Mafi, D Hurley; I Keatley, D Williams; W du Preez, M Sherry, S Archer; B Holland, M O'Driscoll; P O'Mahony capt, T O'Donnell, J Coughlan. Replacements: D Fogarty, J Ryan, J Hayes, D Foley, N Ronan, P Stringer, S Deasy, T Gleeson.
