Sandpaper, a wide assortment of sanding wheels for a dremel, and a shit ton of time and dedication.

Repeatedly move the sandpaper back and forth over the manifold?

It's just like polishing most cast metals. Sand down the roughness using rough paper, gradually change grade until complete. Dremel sanding wheels and an electric sander takes a lot of the hassle out of it.

It's pretty easy, just really time consuming. I must have spent about 8 hours to do the torque strut, 80% of that was just sanding. I used Mothers aluminum polish afterwards, but any quality brand would work.

I used too fine of a sandpaper so it took a whole lot longer than it should have, only had 600+ grit paper in the garage. Using the proper grit sandpaper would cut that time in at least half. A dremel really helps for the polishing, especially the tight little spaces.

Start with a coarse sand paper to smooth down all the high spots and casting marks...then gradually go up to a higher grit until you get it pretty well smooth enough to use a buffing wheel to polish it up to a mirror shine.

Afterwards I'd say clearcoat it but clearcoat has a tendency to flake off due to the inability to ad-hear to the smooth surface. Instead, look into having a clear powercoat applied to it to keep it from oxidizing so it remains shiny. You may also try something like this too...
