The Blues have sold a total of 38,765 tickets for the first two Heineken Cup homes matches this season and are advising supporters who have not purchased tickets that no further tickets will be made available.
"Munster proved they were the best side in Europe last season by beating Biarritz in the final and they have won their opening two matches in this season's competition; they are very much a form side," said Blues captain Xavier Rush.
"Their top players were in good shape in the autumn internationals series, so as a team they will be a very hard prospect for us on Sunday.
"What is clear for anyone to see is that Munster are a very committed side and fly half Ronan O'Gara directs their game plan - he is a key man for them."
