REFLECTOR: IO 360 exhaust

[Tom]

As told to me it's the firing order that causes the 2 into 1 not to be 
as efficient. IE; when 3 is firing, there is still pressure in the pipe 
from when 1 had fired. Suppossedly, this is eliminated by dual 
crossovers and having front cyls on the same pipe and rear cyls on the 
other. Got a neighbor with a Tiger that got a one time STC to do this 
and it really helped his power output. Tom
