[200q20v] source for header for NA I5?

[Fundsalo Racing]

Well, the 'has to be faster theory' (or at least as
fast as I remeber) is more than a theory. I read this
in one of the q books about the introduction of the
4KQ. I will try to dig up the source and report
back..... If I remember right the 4KQ's contemporary
CGT was 110HP and the 4KQ was 115HP due to the
improved exhaust at marketing's request. (sure, I
_could_ have just dreamed all this but.....)
