What do they do to get the 317kw LS3 to 340kw? What is different about the 325kw to 340kw upgrade?

317kw version had the same exhaust midsection as SS, SSV, Redline.(Holden midsection, HSV mufflers)
325kw version had HSV 2.5" full exhaust.
340kw version added a Bimodal intake.

I was under the impression that all the clubsports had the bimodel exhausts? Am I wrong in assuming Bimodal intake and exhaust is the same thing?

Ssv only gets log exhaust manifolds,hsv gets the tri y headers,apparently the 340kw gets 2.5 inch collectors and cats as opposed to 2.25 for the others.
