Here's the rpms when running at 65 mph in 6th - 3rd gear.
6th 3000
5th 3700
4th 4700
3rd 6400
I don't remember what the rpms were with the 5 speed.
Check out this post. BarracksSi and Burgh put some really informative info up about the ratios between the 5 and 6 speed. What Burgh found was the Type S has overall higher gearing in each gear except for 1st and 6th, that means you'll be running at higher rpms in 2nd to 5th. Sixth gear is lower overall than 5th in the Si, so that should benefit cruising. :)
