rm has a "tubular intake manifold and exhaust manifold" (quote jabber)

I know a 3s exhaust manifold will bolt right on to the 5sfe; but what about the intake manifold? And whats a tubular intake manifold, does anyone have links?

--Sean

Well, if you look at stock exhaust and intake manifolds, they have ports that are one piece. But tubular manifolds have tubes or pipes that are separated. The concept between the tubular exhaust and intake manifold are basically the same, but on intake manfiolds its a little more complex.
