REFLECTOR: turning the exhaust exit

[vance atkinson]

In the early days of the EZs we used the two into one pipe.  Then we 
discovered that a single pipe per cylinder gained us 100 RPM  so 
everyone changed over for the free horsepower. They just come straight 
back off the cylinders.  Within the last few years we have discovered 
leaving the pipes cut off inside the cowl, back a few inches from the 
cowl lip for a few more advantages such as Dave has mentioned.
