   Better air flow, better design. The standard Manifold is designed with budget, emmisions, noise, manufacturing costs, material availability etc in mind where as a 4-2-1 is pretty much an all out performance mod.
   
   Anyone know that rover K type engines come with a 4-2-1 as standard? Amazing.

   Plus in mk2's. the cat converter is in the mani. And decatting gives a relatively large improvement in performance as it is. Not to mention the better design of the 4-2-1 in comparison with the standard fanimold.
