You cannot buy an exhaust system for an aircooled Vanagon that you cannot
hear at all.  The closest will be the stock setup for this year, which runs
$299.95, plus $100 more for the catalytic (or about $30 if you want a bypass
pipe instead).  Second closest (and actually very close) will be the system
sold in the U.S. as a stock '72-74 system (but sold in Europe thru '83).
This system does not allow the use of a catalytic converter or EGR valve.
Runs $119.95 for non-stainless, or $189.95 for stainless. Both systems will
be notably quieter than a header/extractor system like you have now, and
will also outlast it by a huge margin.  No other system besides these two
will be notably quieter than what you have now.
