if ur after power fancy buying a lexmaul inlet??? Iv only had it a month and am very happy with it. However I may completely renew my inlet system with a velos plenum. or even go throtle boddies.
cost £430 would prob take £300 for it.
And to be honest if ur doine zaust manifold uv really should do the rest of the system.

Isn't the rear box the weak link on Corsas ?
Think I read that some years ago in revs so it may be wrong. Did'nt notice a big diff from mine replaced middle and back but got it faster from the other bits, s'only 1.2 16v though. That manifold is more bang for your buck. The inlet he mentioned for sale.

with the mods you've listed i would ave thought ur gonna get more back box pressure and not much performance gains as the exhaust gases will flow free'er and quicker from the manifold and de-cat pipe but get caughht up in the standard vauxhall system.
i might be wrong mate but i would have thought you'd be better off getting a full system first THEN get the de-cat and manifold.
