World Pac line are pure crap, i have installed many and i had to start the
job over. Careful here, World Pac as some great parts for Vanagon.

World Pac is an American distributor with some warehouse in Canada. You
can't buy directly from them. They specialize mostly in German parts. In
general they have very good OEM part quality. But, lately, even stuff like
Bossal muffler are made in the Philippine... and that muffler is pure CRAP.
Use the Ernst muffler instead with a good Canadian made Emico Cat.

The best FI line i found so far are the one sold at Small Car. They are
German Mercedes FI line.

To your / the problem: those line crack on the outside layer, even if that
scary it's not critical. Not acceptable but not critical.... still.
