*** SCROLL FOR MORE INFO ***
Comments:
This pipe should NOT be bent in a diameter that is less than 4 times the
radius of the pipe (44mm or 1.73")
Bends in the pipe should be as far as possible AWAY from the threaded part
of the pipe. Final adjustment should be made in steps of only 2-3 at
a time. Repeated adjustment to alter the shape of the pipe will weaken
the pipe and cause it to break.
It is recommended that you use the EX exhaust headers with this flex pipe
if you need a bend right at the exhaust outlet on the cylinder head.
These are available in a "within fuselage" configuration (OSMG2624) and
a "outside fuselage" configuration (OSMG2625).
