Exhaust

OK, time to start building the new header. That will be the only new part for the engine, rest will remain the same. This time we'll use all kinds of cool stuff found from Aalto University's art department's laboratory, like 3d scanner, cad programs and all the cutting and welding tools. Header may not be any better than the previous one but at least it's interesting enough to see what all those gizmos can do.

First we made a simple cutting template for the collector. It's 16 degree collector for saving space and it's also easier to weld than 12 deg.
