I would be curious what's the break down of hp gained by each.

As far as I remember from the tuning section it's all really from the exhaust. The tuning was to reduce lean points, among other minor things, from the less restrictive exhaust rather than any notable increase in power. Remember it adds 18 BHP which is about 14 WHP which is about right for the larger tubing and better H design.
