Subject:      Fri. topic: Adding a resonator=Louder? how come?
Content-Type: text/plain; charset=ISO-8859-1

    Just curious.  I had an Ansa exhaust resonator tip kicking around from a
previous vehicle.  It's got a perforated inner core, sort of like those old
VW muffler tips off a bug, or what you might find on a motorcycle (other
than a Harley, they don't have mufflers, I don't think) grin!

  Putting this onto the end of my exhaust system made it louder.  Adding an
additional muffler makes more sound?

  I have an inline four in my van with a 21/8" ID custom exhaust that goes
though a big straight through (almost) SS Magnaflow oval muffler.  I stuck
this resonator on there, some further experimenting with power and fuel
economy as I am refining my motor transplant...testing.

 Firing it up, it now has a real 'snappy' tone, like a Kiddy Honda or a
Mexican bus...Doesn't make sense to me.  Anybody want to opine why adding a
second 'muffler'  makes it louder?  Friday topic..It is a Vanagon with a VW
motor, though.
