Mine leaked as well when I first installed them.  I found that they really
have to be installed on very clean pipes (if your pipes are original, they
are probably pitted/corroded a bit), not overtightened (that warps the
inside pipe and makes a real mess of things) and gooping them up with
muffler cement doesn't hurt.
