Works on my system, both as individual calls and from a script

$ echo "test" > Test.dat
WS-XP-4960:/home/rthompso> 
$ tar -cf  Test.tar Test.dat
WS-XP-4960:/home/rthompso> 
$ cat Test.tar  | gzip - -c > Test.tar.gz
WS-XP-4960:/home/rthompso> 
$ rm Test.tar
WS-XP-4960:/home/rthompso> 
$ gunzip Test.tar.gz
WS-XP-4960:/home/rthompso> 
$
