not a bad idea at that Soren
i have a pair of cocktail shakers and having the problems with the noise 1 carnt call it a note
i used a lenth of exhaust pipe that fitted inside the muffler all the way to the header put a reducing cone at the header end at the other end i fitted a washer on the locating bolt for the original baffle i was amazed at how quiet it sounded and lost the tinny sound which comes from thin walled mufflers
something along the lines of this a good article on this web site about making baffles
