Exhaust pipes for IOE engines

IOE means Inlet Over Exhaust, i.e. the inlet valve stands upright above the exhaust valve. This counts for most models 1903-1929. The pipes have a diameter of 1-1/4" up to 1924 and 1-3/8" from 1925 onwards. The ends on the cylinder side have a flare and seal on a nipple in the cylinder.
