The race headers for aircooled VWs use a megaphone exhaust.  The primaries
are all equal length, then they all come together in a merged collector.
Bolted to the collector is a 2 foot long megaphone.  The problem with using
this setup on a watercooled VW is the exhaust would exit underneath the
middle of the car.  This isn't a problem with aircooled VWs because the
engine is in the back.
