Hi John,
I believe that the choice of plastic was to minimise weight (in common with the inlet manifold chamber) which isn't unusual.
I'm becoming increasingly convinced that the design is fine so long as the "herbie" clips on the straight pipe are positioned correctly. The criticism I have is that neither RAVE nor Haynes stresses the importance of this. As Christopher has pointed out, the factory assembly typically lasts thirteen years which reinforces this theory.
