The versions of tee(1) that I have allow output to multiple files.
But even if your version of tee(1) only goes to a file and 
standard output, one can redirect standard output to a file:

    dd if=/dev/floppy of=- | tee file1 > file2

or for those who like to throw in gratuitous processes

    dd if=/dev/floppy of=- | tee file1 | cat >file2

or for those with older versions of tee and who want to go to three files

    dd if=/dev/floppy of=- | tee file1 | tee file2  >file3
