I drive  a perfectly functioning 1991 Multivan with about 72k miles.
Nothing wrong  with the motor, so I'm not considering an upgrade there. I
have a K&N  filter installed.

My question to you wise folks is this: what sort of  performance gain, if
any, might I expect from replacing the stock exhaust  system with
something 'better' (e.g. S&S headers, free flow  muffler,....). I'm
looking to increase mileage and, if possible, gain a bit  of power.

Joel, the _STEBRO/Vanagon Stainless Steel  Muffler_ (http://members.aol.
com/Fkc43/stebro.htm)  that I sell is a flow through design.  This reduces the
back pressure on the engine and allows for freer breathing.  Performance
increase about 5% we figure.  We have no access to a dynamometer so have  never done
any accurate testing.  Please consider my STEBRO/Vanagon  Stainless Steel
Exhaust System before making a decision.
