Syncro Vanagon owners have been buying the S&S header exhaust systems from me
and have been pleased with the results.  The complete system (no cat
included) is $280 for the header setup and the turbo muffler.  The quality of
the systems is good and they come with a one year warranty.  The system is
supposed to also give you a horsepower boost (although the actual amount of
boost is unknown right now) by increasing the flow of the exhaust.
Let me know if you are interested.
