The first ever p'art of the day is the exquisite exhaust manifold from the Honda RA 273
Exhaust Manifolds are generally good looking, especially on high output N/A multi cylinder engines but the manifold and collector arrangement on the '66 - '67 F1 entry by Honda is a hard man to beat
The exhaust manifold's basic purpose is to transport exhaust gases out of the cylinders and away from the car, but in this case the exact length, shape and collection point (where the pipes meet) all effect the overall resonance of the system which if correctly tuned can scavenge leftover exhaust gas to maximise volumetric efficiency, in some cases to over 100%.
A few different configurations were tried throughout the season although each is beautiful in its own right
No wonder it was nicknamed the snakepit
(the silver bits on the end are just to stop potential dragoning, who could resist)
