This is the next intake manifold casting project.
Low profile. Fits under a low cowl.
Will come in two sizes 1-1/2 inch pipe and
1-1/4 inch pipe. Sched 40. Incorporates the necessary bell mouths.
Will work with a fabricated sheet metal plenum.

Schedule 40?  Why so heavy, sch 5 would work for intake tubes.  Are you
concerned about supporting the plenum and throttle body?  The injector
bodies need some meat to rest on, but, a couple of gussets and a doubler
should suffice for injector and fuel rail support.  (Of course I have not
actually compared the difference in total weight of the four tubes.)

Yes it would Mike. Sched 40 just happens to be cheaper at
about $15 a bend. When you bend aluminum on a two inch or three
inch inside radius it stretches the material. This can be done
without normalizing the Sched 40 aluminum pipe first then bending 
it and then heat treating it. That is the normal cycle for thin 
aluminum tube bends and why they are so expensive.

It is a cost trade off for a bit more weight. Also it is easier
to tig weld Sched 40.
