One of the things I remember about reading Kent Passer's book "Speed
with Economy" was that he trimmed his exhaust stack so that the end
of the exhaust was effectively right where the air exits the lower cowl.
This has the effect of ejecting the cooling air at a greater velocity
and hence eliminating a very small amount of cooling drag. Has anyone
done this with an RV? What effects were noted if so. I wonder if
this would help with CHT cooling. How much louder would the exhaust
note be in the cockpit. Would the floor boads rattle your legs off?
